The footings of the road bridge are formed of a solid concrete slab which acts as a weir, backing up flow. The height of the drop between the concrete slab and the water level was causing a barrier to fish passage. Previous work was undertaken to place rubble rock at the downstream extent of the concrete slab to enable fish migration; however, this began to function as an additional barrier. The aim of this project was to improve fish passage in one of the culverts, to allow free movement of fish upstream. In order to eliminate the barrier to fish passage, the water levels in the downstream weir pool were raised by the addition of a rock ramp structure.<br /> <br /> Preparation<br /> • The western channel was blocked using temporary dams and pumps to move water through the eastern side of the bridge.

The River Lossie drains an area of approximately 270km² to the sea at Lossiemouth. Flooding in Elgin is not a new problem. Around twenty flood events have been recorded since 1750, with 11 floods in the last 50 years. Most recently Elgin flooded in 1997, 2000, 2002, 2009 and 2014.&lt;/p&gt;<br /> &lt;p&gt;Until recently, during major flood events, key transport links that serve the north east of Scotland have been severed. In 1997 and 2002, the A96 trunk road was closed for more than 48 hours, whilst the Inverness to Aberdeen railway line suffered considerable damage and was closed for several weeks. Flooding has caused great disruption and distress to the community of Elgin. In 2002 over 200 households were evacuated and 10 people had to be airlifted to safety; while the number of flooded homes and businesses was substantially greater.&lt;/p&gt;<br /> &lt;p&gt;The Elgin Flood Alleviation Scheme (FAS) is the single largest to be promoted in Scotland to date. The scheme is designed to provide a current-day standard of defence of 1 in 200 years. The preferred scheme for Elgin was selected on 25 February 2004. A Flood Prevention Order was publicised in October 2007 and a planning application submitted in January 2008. Scottish Ministers confirmed the scheme in December 2010, with construction starting in April 2011. Construction is due to complete in 2015. The scheme protects around 750 residential properties and 250 businesses.&lt;/p&gt;<br /> &lt;p&gt;The scheme includes:&lt;br&gt;<br /> • The restoration of an expansive blue/green corridor through Elgin reflecting both the historic and natural setting of the watercourse.&lt;br&gt;<br /> • The creation of a two-stage channel within the flood corridor, through the centre of the town, by floodplain lowering allowing flood flows to pass safely through Elgin.&lt;br&gt;<br /> • The creation of a new flood relief channel opposite Elgin Cathedral and a new natural channel to move the Tyock confluence approximately 1.5km downstream to address flood risk in New Elgin.&lt;br&gt;<br /> • Setting back flood embankments and flood walls from Glen Moray Distillery in the west to the new confluence of the Tyock/Linkwood diversion channel with the River Lossie in the east.&lt;br&gt;<br /> • Replacement and construction of three bridges to increase flood resilience and improve access. The innovative Landshut Bridge was designed within the historic context of the area surrounding Elgin Cathedral and Pans Port providing an understated structure with high architectural merit.<br /> |Monitoring surveys and results=Integrated and science-based monitoring has illustrated positive change over the course of the project. Baseline geomorphology, ecology, and water chemistry surveying and repeat surveys during construction within and adjacent to the scheme footprint have enabled the design of the scheme to progress in a way which protects the existing characteristics of the area.&lt;/p&gt;<br /> &lt;p&gt;The scheme monitoring includes:&lt;br&gt;<br /> • Geomorphological surveys identified areas where bank protection was required and on-going monitoring will be undertaken to ensure that erosion is mitigated.&lt;br&gt; <br /> • Water chemistry sampling has proven that the water treatment feature has been successful in removing dieldrin from the Tyock Burn.&lt;br&gt; <br /> • Continued monitoring of the newly established areas of wetland, riparian and wildflower meadow planting will be required to ensure that these biodiverse habitats flourish.&lt;br&gt; <br /> • Large areas of giant hogweed and Japanese knotweed have been treated over the past seven years. On-going monitoring and action will be required to ensure that these do not return to the area.&lt;br&gt; <br /> • Bat and bird boxes will continue to be monitored and maintained as required.&lt;br&gt; <br /> • Aerial surveys will continue into the future to undertake wide scale assessments.<br /> |Lessons learn=The same integrated project team has worked on five separate flood alleviation schemes protecting four communities in Moray under the banner of Moray Flood Alleviation. These schemes represent an investment totaling £180 million over a fifteen year period. This has been key to the success of the project.&lt;/p&gt;<br /> &lt;p&gt;The project team operates a “continuous improvement” philosophy, using regular lessons learnt workshops to ensure that time and money is not wasted on avoidable mistakes in the future. Over the course of the project the team has developed a collaborative and efficient way of working. Currently the project is set to come in £10 million below budget. Four of the five schemes have been completed on time with Elgin scheduled to finish on time this year, 15 years after the start of the project. The project team has been co-located in the same open plan office throughout the scheme’s development and delivery ensuring matters are discussed easily and decisions are made quickly.&lt;/p&gt; <br /> <br /> &lt;p&gt;During the development of the design for the scheme, the implementation of the Water Framework Directive was in its infancy. Working closely with SEPA, the team were able to predict the implications of the Directive and design a scheme which complemented the requirements. Meeting with SEPA on a monthly basis has resulted in a sound relationship where issues have been discussed and resolved promptly.&lt;/p&gt; <br /> <br /> &lt;p&gt;The Elgin scheme has been shortlisted for the ACE/NCE 2015 Outstanding Achievement Award, which recognises schemes that have made a contribution to the reputation of consultancy and engineering. The team has also twice been commended by The Saltire Society at their Awards for Civil Engineering; in 2010 for the Forres FAS for a &lt;i&gt;“well managed and well executed FAS, constructed with high regard for the environment”&lt;/i&gt;, and in 2012 for the Rothes FAS for &lt;i&gt;“the co-operation, goodwill and ingenuity demonstrated by the team, coupled with the response elicited from the community.”&lt;/i&gt;&lt;/p&gt;<br /> <br /> &lt;p&gt;&lt;i&gt;“In more ways than one our community has been given a new lease of life and features have been created that complement the authentic architecture and public face of our village.”&lt;/i&gt;&lt;br&gt; <br /> Rev Bob Anderson, Rothes Parish Minister&lt;/p&gt;<br /> <br /> &lt;p&gt;&lt;i&gt;“I challenged the team to deliver flood alleviation and complement the environment. My measure of success was that the Scheme should be “invisible” and prevent flooding. Not only was the challenge met, but the Scheme was delivered ahead of programme and under budget.

These works have straightened the channel, increasing the width and depth in many places. <br /> The Spring meadow site is on the north eastern bank of the river at Sheffield Park, within the High Weald Area of Outstanding Natural Beauty (AONB). The site was acquired by the current landowner to increase wildlife value in the area. Since conception in 2010, works on site were finished in 16 weeks and the project was completed in 2012. Initially it had been hoped to complete works in 8 weeks, however heavy rainfall caused a relatively short delay. <br /> <br /> <br /> The Sheffield Park Meanders project involved the reinstatement of the historic meandering course of the Ouse at spring meadow to achieve the following aims:<br /> <br /> • Reinstate the historic course of the river through the re-excavation of the visible meander. The creation of a meandering channel allows a greater diversity of habitats to develop, specifically for multiple fish species. <br /> <br /> • Reduce flood risk by creating a longer meandering channel length, which slows the flow of water heading downstream. At the same time the new bank profiling aimed to encourage natural functioning of the floodplain. <br /> <br /> • The incorporation of a low flow channel which maintains sufficient water depth for fish migration in all flow conditions. <br /> <br /> • Restoration of existing wet meadow habitats at the site and creation of new woodland areas. <br /> <br /> <br /> Initially a 20 meter trial area was excavated, allowing adjustments to be made on expert on site recommendation. Banks were roughened up with a toothed bucket to ensure an undulating bank profile. Spoil from excavation was spread across a railway embankment close by to reduce the cost of disposal.<br /> <br /> The project was named the Professional category winner at the annual Wild Trout Trust (WTT) Conservation Awards 2013. The panel comprised two experts, Paul Gaskell (WTT) and Dr. Jenny Mant from the River Restoration Centre.<br /> <br /> The project is one of thirteen projects within the Middle Ouse Restoration of Physical Habitats (MORPH) project; led by the Environment Agency in partnership with the Ouse &amp; Adur Rivers Trust (OART) &amp; supported by Royal HaskoningDHV (design, engineering and environmental consultancy services) and C A Blackwell (contractor for the implementation works). Each of these projects is being considered individually but also in terms of how they will work in conjunction with each other to improve the diversity of the river and reduce flood risk. <br /> <br /> <br /> Several details were built into the design to meet the site specific requirements. A ford was constructed to give access to a newly created island area in the centre of the channel. Woody material was added to the new channel at five locations to encourage flow diversity and provide the channel with some shade. The existing channel and new meandering course are joined via a bund constructed at the upstream confluence of the two channels. At normal flow levels this directs all the flow down the mender, leaving the old course as a backwater. In times of flood the bund can be overtopped, allowing water to flow down both channels, increasing local flood capacity. <br /> <br /> The land surrounding the site is in Higher Level Stewardship scheme for floodplain hay meadow. The island at the centre of the site was no longer manageable as a hay meadow, therefore a Forestry Commission Woodland Creation Grant was approved to create 1.5Ha of floodplain woodland. This area would slow the flow of flood waters, help to trap sediment and increase biodiversity of the site. <br /> Promotion of the project included coverage on BBC South East today programme, local papers and area group websites.<br /> |Monitoring surveys and results=Working with University of Brighton, the project has set up a long term monitoring programme to look at and assess geomorphological changes, seed dispersal of Himalayan Balsam, and hay meadow restoration techniques.<br /> |Lessons learn=The design of the new two-stage channel (incorporating a low flow channel) has increased water depth during low flows. In combination with a greater variety of channel widths and depths, this has increased habitat diversity which should benefit fish populations. <br /> <br /> Within a year of the project works, native vegetation had begun to establish on the banks. This will provide shelter and feeding areas for fish during high flows and will increase habitat for invertebrate species such as dragonflies, beetles and fly species.<br /> <br /> The newly created backwater will provide refuge for juveile fish, create warmer conditions and shallow refugia as nursey areas for young amphibians and invertebrates which live in still water. The introduction of woody material provides shelter during low flows and marginal shelves will become vegetated and provide areas for feeding and resting.<br /> <br /> Out of channel habitat enhancement of floodplain woodland and additional lateral connectivity is expected to lead to improvements in the biodiversity value of the landscape (wet meadow habitats are nationally rare) &amp; reduce flood risk downstream by increasing capacity for floodwaters. <br /> <br /> The public have been consulted and kept informed of progress throughout the project, building local support for river restoration and its associated benefits.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=2013-10-24 12.26.30.jpg<br /> |Caption=Upstream part of the project where Himalayan Balsam will need to be managed - © Nick Elbourne (RRC), October 2013<br /> }}<br /> {{Case study image<br /> |File name=2013-10-24 12.44.15.jpg<br /> |Caption=Re-instated meander, looking downstream - © Nick Elbourne (RRC), October 2013<br /> }}<br /> {{Case study image<br /> |File name=2013-10-24 12.52.37.jpg<br /> |Caption=Constructed river crossing (Ford) - © Nick Elbourne (RRC), October 2013<br /> }}<br /> {{Case study image<br /> |File name=Sheffield Park Ouse Spring Meadow.jpg<br /> |Caption=River Ouse at Sheffield Park/Spring Meadow post restoration © Royal HaskoningDHV<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Ouse from Cockhaise Brook confluence to Spithurst<br /> }}<br /> {{Site<br /> |Name=River Ouse at Sheffield Green<br /> |WFD water body code=GB107041012710<br /> |WFD (national) typology=Low, Medium, Siliceous<br /> |WFD water body name=Ouse from Cockhaise Brook confluence to Spithurst<br /> |Pre-project morphology=Trapezoidal, Impounded, Over-widened, Uniform bed<br /> |Reference morphology=2-stage channel, <br /> |Desired post project morphology=Width and depth variation, 2-stage channel, <br /> |Heavily modified water body=Yes<br /> |Protected species present=No<br /> |Invasive species present=Yes<br /> |Species=Himalayan balsam (Impatiens glandulifera ), <br /> |River corridor land use=Wet meadow, Rough unimproved grassland/pasture, Woodland, <br /> }}<br /> {{Project background<br /> |Reach length directly affected=400<br /> |Works started=2012/09/01<br /> |Works completed=2012/12/24<br /> |Total cost category=100 - 500 k€<br /> |Total1 cost=150<br /> |Funding sources=DEFRA, <br /> |Investigation and design Lead organisation=Royal HaskoningDHV<br /> |Investigation and design Other contact forename=Ian<br /> |Investigation and design Other contact surname=Dennis<br /> |Stakeholder engagement Lead organisation=Ouse and Adur Rivers Trust<br /> |Stakeholder engagement Other contact forename=Peter<br /> |Stakeholder engagement Other contact surname=King<br /> |Works and supervision Lead organisation=Ouse and Adur Rivers Trust<br /> |Works and supervision Other contact forename=Peter<br /> |Works and supervision Other contact surname=King<br /> |Post-project management and maintenance Lead organisation=Ouse and Adur Rivers Trust<br /> |Post-project management and maintenance Other contact forename=Peter<br /> |Post-project management and maintenance Other contact surname=King<br /> |Monitoring Lead organisation=University of Brighton<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Barriers to fish migration, <br /> |Hydromorphological quality elements=Quantity &amp;

This Environment Agency owned and maintained structure on the Knepp estate on the Western arm of the Adur was preventing fish passage and impounding the river upstream. <br /> In partnership with the Ouse and Adur Rivers Trust (OART) the South Downs Fisheries and Biodiversity team led a project to remove the gate and stabilise the clay banks with brushwood terracing. This not only removed a significant barrier to fish passage but it has also helped restore natural river processes which will be beneficial to wider biodiversity as whole. <br /> The Arun and Adur operations field team with specialist help from the Ouse operations field team were the main contractors. Using their experience of the Knepp restoration project just downstream they carried out a very professional job and were praised by the designers, OART and everyone else involved with the project. <br /> The Arun and Adur Asset Performance Team helped with the engineering aspect as well as contractor management and finance. <br /> <br /> This project has achieved Water Framework Directive (WFD) objectives for this waterbody and is an excellent example of another successful partnership project with OART.<br /> |Monitoring surveys and results=A fish survey was carried out before the structure was completely removed and this data will be used to compare future surveys and monitor the effects this project has had on the existing fish communities and whether the work has increased the diversity of species present in this stretch of the Adur.<br /> |Lessons learn=Starting this project late in the year meant we had had to pull out when the weather turned. The welfare unit left on site was repeatedly flooded costing the project up to £40,000. Lesson learnt, try and secure funding as early as possible so you can programme the works to co-incide with the nice weather.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=R.

This extensive modification created a deep, uniform trapezoidal channel that supported very little flow or habitat diversity and was largely cut off from its floodplain in all but the largest floods. The extent of channel enlargement meant that flows became very low during dry summer periods, with parts of the river resembling a series of connected ponds rather than a flowing channel.

As a result, the rivers do not provide the full range of habitats expected and fish populations are not as good as they could be. Two hundred years on, the River Ouse and Adur catchment was selected as one of 10 Environment Agency-led pilot catchments in which to test different approaches for partnership working under the new Catchment Based Approach (CaBA) to collaborative Water Framework Directive (WFD) implementation. <br /> <br /> The £1 million MORPH project, which was funded through the Catchment Restoration Fund, was established to deliver significant improvements to the ecology of the catchment by renaturalising the watercourse and reversing the impact that historical modifications have had on the catchment. <br /> The project had two main aims:<br /> * To implement the objectives of the WFD by improving fish passage and the hydromorphology of the river.<br /> * To implement natural flood management actions identified within the River Ouse Catchment Flood Management Plan, by increasing floodplain water storage to alleviate flooding downstream.<br /> <br /> In order to deliver these aims, the project has so far:<br /> * Removed a redundant weir at Buxted Park, seeded gravel in the channel and allowed natural processes to operate on the river bed and banks in a controlled way.<br /> * Bypassed a second structure at Spring Meadow, creating a nature-like channel with a diverse range of habitats that is well connected to its floodplain. <br /> * Installed a rock ramp (the first of its kind in the UK) to allow fish to pass upstream of a culvert beneath a historic road bridge.<br /> <br /> The river restoration works have renaturalised the river and delivered significant benefits for the ecology of the river and floodplain. Improving fish passage has helped priority fish species listed in the UK Biodiversity Action Plan as needing conservation action, and more natural in-channel and floodplain habitats have contributed towards delivering WFD requirements. The Buxted Park and Sheffield Park schemes have also helped to reconnect the river to its floodplain and encourage more frequent flooding, contributing to a reduction in flood risk to sensitive areas downstream. <br /> <br /> In addition to these tangible on-the-ground achievements, the project has demonstrated that catchment partnerships can be extremely successful in delivering considerable results in a short period of time. This has galvanised local support, resulting in volunteers planting a wet woodland and other landowners actively exploring river restoration opportunities.<br /> |Monitoring surveys and results=The project is regarded by the partnership and other organisations as being extremely successful. Key evidence of this success includes:<br /> <br /> * alongside fisheries surveys, botanical and invertebrate surveys, the partnership is U. The geomorphological surveys have highlighted minor adjustments that demonstrate that natural processes are operating as intended. H, it is provide of the ecological<br /> * The project has enabled a sustainable partnership to be established between the different organisations that have been involved. The partnership continues to be very strong, with an established group of volunteers and several landowners (including the National Trust) expressing a strong interest in undertaking river restoration with the wider partnership on their land. The project team consider this to be an important indicator of a successful project. <br /> * The MORPH project was the winner of the Professional Category in the prestigious Wild Trout Trust Conservation Awards 2013. In addition, the project was Highly Commended in the Sustainability and Environment Category of the Institution of Civil Engineers South East Engineering Excellence Awards 2013. This recognition by two leading independent bodies clearly demonstrates the success of the project in delivering real environmental benefits on the ground, successfully restoring natural processes, and raising the local profile of river restoration. <br /> * This recognition is also reflected in the selection of the project to be showcased at the 2013 European River Restoration Conference and the 2013 River Restoration Centre Annual Networking Conference. <br /> * Furthermore, the project has received coverage in the national press, being featured heavily in an article in the February 2014 The Environment Magazine entitled “Partnership Pays” published by the Chartered Institution of Water and Environmental Management. <br /> * The project has been a high profile project in the Sussex area, receiving coverage in the local press, local blogs and websites along with being featured on the BBC News. Articles have also been published in the Mid Sussex Times and The Sunny Times for Buxted Park.<br /> * The BBC South East Today news programme covered the project in November 2012 and held interviews with project team members at Spring Meadow, focussing on river restoration and ecology. The segment also included flyovers of the site pre-works.<br /> * The Environment Agency and Royal HaskoningDHV have been presenting elements of the project to other areas of the Environment Agency South East region promoting the team’s achievements and promoting the good design, construction and programme management achievements.<br /> * Tand project implementation, .<br /> |Lessons learn=One of the key challenges of working at a catchment scale was rationalising catchment-wide WFD pressures and prioritising actions so that the greatest environmental and social benefits could be progressed. As in any catchment with a wide range of stakeholders, it has also been a great challenge to ensure that environmental requirements are balanced with the needs of local stakeholders. We have been able to overcome these challenges by working closely with stakeholders and developing a strategic plan which determines priorities and identifies “quick win sites” where limited constraints can allow construction to be progressed within a limited funding window.<br /> <br /> keyfor OARTthe<br /> The key lessons learned while addressing these challenges and delivering the project include:<br /> * The most important lesson is that pre project work in getting public and focused stakeholder support is vital in achieving the objectives. By working closely with landowners and other stakeholders at the beginning, listening to their concerns and incorporating these into initial designs, the projects run smoothly and at a faster pace as there is agreement right from the start.<br /> <br /> Effective partnership working can enable delivery in a short time when funding is secure. On the ground input from the OART catchment officer has greatly assisted the Environment Agency in building and maintaining partnerships.<br /> * The phased approach to design and construction allows lessons and best practice to be shared across sites. This ensures that the projects successfully deliver maximum benefits in an efficient and effective way. <br /> * Ensuring that the projects deliver wider environmental and social objectives has helped to guarantee the success of the project and maintain widespread support. <br /> * There is a clear requirement to manage stakeholder expectations through the project implementation stage so they are not surprised when sites get temporarily messy during construction. <br /> * Investment at the quick win sites has acted as a catalyst to encourage other groups to undertake improvement works at different sites in the catchment.<br /> <br /> The lessons learnt from these projects will be used by the Environment Agency and OART to guide their future catchment restoration activities in the Ouse and Adur catchments. The lessons can also be applied to other catchments as part of the Environment Agency’s Catchment Based Approach to WFD implementation.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Sharpsbridge rock ramp.jpg<br /> |Caption=Sharpsbridge rock ramp fish easement post construction © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=Sharpsbridge under construction 2.JPG<br /> |Caption=Sharpsbridge rock ramp under construction © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=Sheffield Park Ouse Spring Meadow.jpg<br /> |Caption=River Ouse at Sheffield Park/Spring Meadow post restoration © Royal HaskoningDHV <br /> }}<br /> {{Case study image<br /> |File name=Uck Buxted Park.jpg<br /> |Caption=River Uck at Buxted Park weir removal post works © Royal HaskoningDHV<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Uck Updtream of Buxted<br /> }}<br /> {{Site<br /> |Name=Middle Ouse<br /> |WFD (national) typology=Lowland, <br /> |Pre-project morphology=Straightened, <br /> |Heavily modified water body=Yes<br /> |Site designation=UK - Areas of Outstanding Natural Beauty<br /> |Local site designation=UK - Site of Special Scientific Interest, <br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> |Dominant substrate=Clay, <br /> |River corridor land use=Agriculture (Arable), Improved/semi-improved grassland/pasture, Broadleaf/mixed woodland (semi natural), Ancient woodland, Rough unimproved grassland/pasture, Urban, <br /> |Average bankfull channel width category=2 - 5 m<br /> |Average bankfull channel depth category=2 - 5 m<br /> }}<br /> {{Project background<br /> |Project started=2011/12/01<br /> |Works started=2012/07/09<br /> |Total cost category=100 - 500 k€<br /> |Investigation and design Lead organisation=Royal HaskoningDHV<br /> |Investigation and design Other contact forename=Alex<br /> |Investigation and design Other contact surname=Lee<br /> |Stakeholder engagement Lead organisation=Ouse and Adur Rivers Trust<br /> |Stakeholder engagement Other contact forename=Peter<br /> |Stakeholder engagement Other contact surname=King<br /> |Works and supervision Lead organisation=Environment Agency<br /> |Works and supervision Other contact forename=Lisa<br /> |Works and supervision Other contact surname=Twohig<br /> |Post-project management and maintenance Lead organisation=Ouse and Adur Rivers Trust<br /> |Post-project management and maintenance Other contact forename=Peter<br /> |Post-project management and maintenance Other contact surname=King<br /> |Monitoring Lead organisation=Ouse and Adur Rivers Trust<br /> |Monitoring Other contact forename=Peter<br /> |Monitoring Other contact surname=King<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Barriers to fish migration, Flood risk management, Impoundments (not hydropower),<br /> |Hydromorphological quality elements=Quantity &amp; dynamics of flow, Freshwater flow regime, Width &amp; depth variation, <br /> |Biological quality elements=Fish: Abundance, Fish: Species composition, Invertebrates: Abundance, <br /> |Other motivation=In-channel and Riparian habitat improvements<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Alteration in channel dimensions, Bank improvement, Weir removal, Reintroduction of natural features i.e. meanders and gravel bed, rock ramp construction<br /> |Floodplain / River corridor=Creation of wet woodland, Control of invasive species, <br /> |Planform / Channel pattern=Creation of fish pass, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> <br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

The London Borough of Croydon believes that the park is presently an underused asset and wishes to restore the park to reflect is original Victorian lay out.<br /> The main objectives of the project are as follows: Restore the river corridor through Wandle Park improving the habitat for local wildlife; Provide flood risk benefit for properties downstream to approximately 1 in 50 return period; Providethe local community with an opportunity to enjoy a high-quality environment and encourage people to care for, use, appreciate and enjoy the environment; Improve the water quality in the channel in support of the Water Framework Directive, helping to meet Good Ecological Potential (GEP) in the catchmentand; Provideflood storagethat will contribute to the London Rivers Action Plan.<br /> <br /> Update (July 2015)<br /> The London Borough of Croydon worked in partnership with Royal HaskoningDHV and LDA Design to oversee the design and implementation of an ambitious scheme to regenerate Wandle Park, improving an important green space into an asset for the local community and contributing towards the delivery of WFD objectives. At the heart of this ambitious £2 million scheme was the restoration of over 250m of the River Wandle, previously culverted below ground, into an open, naturally functioning meandering channel. This project was Highly Commended at the 2015 Landscape Institute Awards.<br /> |Lessons learn=This project had a range of key challenges that were overcome through the design process, including:<br /> • The restoration of natural hydromorphological processes whilst minimising the potential for large scale channel migration. This was resolved through the design of a multi-stage channel which allows the low flow channel to adjust within a more permanent high flow bank line. Seeded gravels were also allowed to rework naturally to create a wide range of in-channel habitat niches. The two stage channel safely accommodates both the low dry weather flows and the high flood flows.<br /> • Ensuring that the river could be re-meandered through contaminated land at the site without increasing remobilisation of in situ contaminated sediments and leachate. An uncontaminated capping layer using uncontaminated soils was used to protect the environment and park users from contaminated materials. <br /> • Minimising the need for expensive off-site disposal of contaminated materials and the need to import uncontaminated soils for capping. Soils on the site were categorized as contaminated and less contaminated (i.e. with contaminant concentrations below hazardous levels), and the former were used as a base layer for landscape features within the park. These were capped with less contaminated soils from the site to prevent exposure to the wider environment.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=During works.jpg<br /> |Caption=During works<br /> }}<br /> {{Case study image<br /> |File name=3665 140416 009.JPG<br /> |Caption=Post restoration, April 2014 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=DSC 0144.JPG<br /> |Caption=Post restoration, June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=2996 130605 River Pano (2).jpg<br /> |Caption=Post restoration panoramic, June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=DSC 0090.JPG<br /> |Caption=New river crossing, June 2013 June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Wandle (Croydon to Wandsworth) and the R.

This was resolved through the design of a multi-stage channel which allows the low flow channel to adjust within a more permanent high flow bank line. Seeded gravels were also allowed to rework naturally to create a wide range of in-channel habitat niches. The two stage channel safely accommodates both the low dry weather flows and the high flood flows.<br /> • Ensuring that the river could be re-meandered through contaminated land at the site without increasing remobilisation of in situ contaminated sediments and leachate. An uncontaminated capping layer using uncontaminated soils was used to protect the environment and park users from contaminated materials. <br /> • Minimising the need for expensive off-site disposal of contaminated materials and the need to import uncontaminated soils for capping. Soils on the site were categorized as contaminated and less contaminated (i.e. with contaminant concentrations below hazardous levels), and the former were used as a base layer for landscape features within the park. These were capped with less contaminated soils from the site to prevent exposure to the wider environment. <br /> <br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=During works.jpg<br /> |Caption=During works<br /> }}<br /> {{Case study image<br /> |File name=3665 140416 009.JPG<br /> |Caption=Post restoration, April 2014 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=DSC 0144.JPG<br /> |Caption=Post restoration, June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=2996 130605 River Pano (2).jpg<br /> |Caption=Post restoration panoramic, June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Case study image<br /> |File name=DSC 0090.JPG<br /> |Caption=New river crossing, June 2013 June 2013 © Royal HaskoningDHV<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Wandle (Croydon to Wandsworth) and the R.

As a result, the rivers do not provide the full range of habitats expected and fish populations are not as good as they could be. Two hundred years on, the River Ouse and Adur catchment was selected as one of 10 Environment Agency-led pilot catchments in which to test different approaches for partnership working under the new Catchment Based Approach (CaBA) to collaborative Water Framework Directive (WFD) implementation. <br /> <br /> The £1 million MORPH project, which was funded through the Catchment Restoration Fund, was established to deliver significant improvements to the ecology of the catchment by renaturalising the watercourse and reversing the impact that historical modifications have had on the catchment. <br /> The project had two main aims:<br /> * To implement the objectives of the WFD by improving fish passage and the hydromorphology of the river.<br /> * To implement natural flood management actions identified within the River Ouse Catchment Flood Management Plan, by increasing floodplain water storage to alleviate flooding downstream.<br /> <br /> In order to deliver these aims, the project has so far:<br /> * Removed a redundant weir at Buxted Park, seeded gravel in the channel and allowed natural processes to operate on the river bed and banks in a controlled way.<br /> * Bypassed a second structure at Spring Meadow, creating a nature-like channel with a diverse range of habitats that is well connected to its floodplain. <br /> * Installed a rock ramp (the first of its kind in the UK) to allow fish to pass upstream of a culvert beneath a historic road bridge.<br /> <br /> The river restoration works have renaturalised the river and delivered significant benefits for the ecology of the river and floodplain. Improving fish passage has helped priority fish species listed in the UK Biodiversity Action Plan as needing conservation action, and more natural in-channel and floodplain habitats have contributed towards delivering WFD requirements. The Buxted Park and Sheffield Park schemes have also helped to reconnect the river to its floodplain and encourage more frequent flooding, contributing to a reduction in flood risk to sensitive areas downstream. <br /> <br /> In addition to these tangible on-the-ground achievements, the project has demonstrated that catchment partnerships can be extremely successful in delivering considerable results in a short period of time. This has galvanised local support, resulting in volunteers planting a wet woodland and other landowners actively exploring river restoration opportunities.<br /> |Monitoring surveys and results=The project is regarded by the partnership and other organisations as being extremely successful. Key evidence of this success includes:<br /> <br /> * alongside fisheries surveys, botanical and invertebrate surveys, the partnership is U. The geomorphological surveys have highlighted minor adjustments that demonstrate that natural processes are operating as intended. H, it is provide of the ecological<br /> * The project has enabled a sustainable partnership to be established between the different organisations that have been involved. The partnership continues to be very strong, with an established group of volunteers and several landowners (including the National Trust) expressing a strong interest in undertaking river restoration with the wider partnership on their land. The project team consider this to be an important indicator of a successful project. <br /> * The MORPH project was the winner of the Professional Category in the prestigious Wild Trout Trust Conservation Awards 2013. In addition, the project was Highly Commended in the Sustainability and Environment Category of the Institution of Civil Engineers South East Engineering Excellence Awards 2013. This recognition by two leading independent bodies clearly demonstrates the success of the project in delivering real environmental benefits on the ground, successfully restoring natural processes, and raising the local profile of river restoration. <br /> * This recognition is also reflected in the selection of the project to be showcased at the 2013 European River Restoration Conference and the 2013 River Restoration Centre Annual Networking Conference. <br /> * Furthermore, the project has received coverage in the national press, being featured heavily in an article in the February 2014 The Environment Magazine entitled “Partnership Pays” published by the Chartered Institution of Water and Environmental Management. <br /> * The project has been a high profile project in the Sussex area, receiving coverage in the local press, local blogs and websites along with being featured on the BBC News. Articles have also been published in the Mid Sussex Times and The Sunny Times for Buxted Park.<br /> * The BBC South East Today news programme covered the project in November 2012 and held interviews with project team members at Spring Meadow, focussing on river restoration and ecology. The segment also included flyovers of the site pre-works.<br /> * The Environment Agency and Royal HaskoningDHV have been presenting elements of the project to other areas of the Environment Agency South East region promoting the team’s achievements and promoting the good design, construction and programme management achievements.<br /> * Tand project implementation, .<br /> |Lessons learn=One of the key challenges of working at a catchment scale was rationalising catchment-wide WFD pressures and prioritising actions so that the greatest environmental and social benefits could be progressed. As in any catchment with a wide range of stakeholders, it has also been a great challenge to ensure that environmental requirements are balanced with the needs of local stakeholders. We have been able to overcome these challenges by working closely with stakeholders and developing a strategic plan which determines priorities and identifies “quick win sites” where limited constraints can allow construction to be progressed within a limited funding window.<br /> <br /> keyfor OARTthe<br /> The key lessons learned while addressing these challenges and delivering the project include:<br /> * The most important lesson is that pre project work in getting public and focused stakeholder support is vital in achieving the objectives. By working closely with landowners and other stakeholders at the beginning, listening to their concerns and incorporating these into initial designs, the projects run smoothly and at a faster pace as there is agreement right from the start.<br /> <br /> Effective partnership working can enable delivery in a short time when funding is secure. On the ground input from the OART catchment officer has greatly assisted the Environment Agency in building and maintaining partnerships.<br /> * The phased approach to design and construction allows lessons and best practice to be shared across sites. This ensures that the projects successfully deliver maximum benefits in an efficient and effective way. <br /> * Ensuring that the projects deliver wider environmental and social objectives has helped to guarantee the success of the project and maintain widespread support. <br /> * There is a clear requirement to manage stakeholder expectations through the project implementation stage so they are not surprised when sites get temporarily messy during construction. <br /> * Investment at the quick win sites has acted as a catalyst to encourage other groups to undertake improvement works at different sites in the catchment.<br /> <br /> The lessons learnt from these projects will be used by the Environment Agency and OART to guide their future catchment restoration activities in the Ouse and Adur catchments. The lessons can also be applied to other catchments as part of the Environment Agency’s Catchment Based Approach to WFD implementation.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Uck Updtream of Buxted<br /> }}<br /> {{Site<br /> |Name=Middle Ouse<br /> |WFD (national) typology=Lowland, <br /> |Pre-project morphology=Straightened, <br /> |Heavily modified water body=Yes<br /> |Site designation=UK - Areas of Outstanding Natural Beauty<br /> |Local site designation=UK - Site of Special Scientific Interest, <br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> |Dominant substrate=Clay, <br /> |River corridor land use=Agriculture (Arable), Improved/semi-improved grassland/pasture, Broadleaf/mixed woodland (semi natural), Ancient woodland, Rough unimproved grassland/pasture, Urban, <br /> |Average bankfull channel width category=2 - 5 m<br /> |Average bankfull channel depth category=2 - 5 m<br /> }}<br /> {{Project background<br /> |Project started=2011/12/01<br /> |Works started=2012/07/09<br /> |Total cost category=100 - 500 k€<br /> |Investigation and design Lead organisation=Royal HaskoningDHV<br /> |Investigation and design Other contact forename=Alex<br /> |Investigation and design Other contact surname=Lee<br /> |Stakeholder engagement Lead organisation=Ouse and Adur Rivers Trust<br /> |Stakeholder engagement Other contact forename=Peter<br /> |Stakeholder engagement Other contact surname=King<br /> |Works and supervision Lead organisation=Environment Agency<br /> |Works and supervision Other contact forename=Lisa<br /> |Works and supervision Other contact surname=Twohig<br /> |Post-project management and maintenance Lead organisation=Ouse and Adur Rivers Trust<br /> |Post-project management and maintenance Other contact forename=Peter<br /> |Post-project management and maintenance Other contact surname=King<br /> |Monitoring Lead organisation=Ouse and Adur Rivers Trust<br /> |Monitoring Other contact forename=Peter<br /> |Monitoring Other contact surname=King<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Barriers to fish migration, Flood risk management, Impoundments (not hydropower),<br /> |Hydromorphological quality elements=Quantity &amp; dynamics of flow, Freshwater flow regime, Width &amp; depth variation, <br /> |Biological quality elements=Fish: Abundance, Fish: Species composition, Invertebrates: Abundance, <br /> |Other motivation=In-channel and Riparian habitat improvements<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Alteration in channel dimensions, Bank improvement, Weir removal, Reintroduction of natural features i.e. meanders and gravel bed, rock ramp construction<br /> |Floodplain / River corridor=Creation of wet woodland, Control of invasive species, <br /> |Planform / Channel pattern=Creation of fish pass, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> <br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

We have been able to overcome these challenges by working closely with stakeholders and developing a strategic plan which determines priorities and identifies “quick win sites” where limited constraints can allow construction to be progressed within a limited funding window.<br /> <br /> keyfor OARTthe<br /> The key lessons learned while addressing these challenges and delivering the project include:<br /> * The most important lesson is that pre project work in getting public and focused stakeholder support is vital in achieving the objectives. By working closely with landowners and other stakeholders at the beginning, listening to their concerns and incorporating these into initial designs, the projects run smoothly and at a faster pace as there is agreement right from the start.<br /> <br /> Effective partnership working can enable delivery in a short time when funding is secure. On the ground input from the OART catchment officer has greatly assisted the Environment Agency in building and maintaining partnerships.<br /> * The phased approach to design and construction allows lessons and best practice to be shared across sites. This ensures that the projects successfully deliver maximum benefits in an efficient and effective way. <br /> * Ensuring that the projects deliver wider environmental and social objectives has helped to guarantee the success of the project and maintain widespread support. <br /> * There is a clear requirement to manage stakeholder expectations through the project implementation stage so they are not surprised when sites get temporarily messy during construction. <br /> * Investment at the quick win sites has acted as a catalyst to encourage other groups to undertake improvement works at different sites in the catchment.<br /> <br /> The lessons learnt from these projects will be used by the Environment Agency and OART to guide their future catchment restoration activities in the Ouse and Adur catchments. The lessons can also be applied to other catchments as part of the Environment Agency’s Catchment Based Approach to WFD implementation.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Uck Updtream of Buxted<br /> }}<br /> {{Site<br /> |Name=Middle Ouse<br /> |WFD (national) typology=Lowland, <br /> |Pre-project morphology=Straightened, <br /> |Heavily modified water body=Yes<br /> |Site designation=UK - Areas of Outstanding Natural Beauty<br /> |Local site designation=UK - Site of Special Scientific Interest, <br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> |Dominant substrate=Clay, <br /> |River corridor land use=Agriculture (Arable), Improved/semi-improved grassland/pasture, Broadleaf/mixed woodland (semi natural), Ancient woodland, Rough unimproved grassland/pasture, Urban, <br /> |Average bankfull channel width category=2 - 5 m<br /> |Average bankfull channel depth category=2 - 5 m<br /> }}<br /> {{Project background<br /> |Project started=2011/12/01<br /> |Works started=2012/07/09<br /> |Total cost category=100 - 500 k€<br /> |Investigation and design Lead organisation=Royal HaskoningDHV<br /> |Investigation and design Other contact forename=Alex<br /> |Investigation and design Other contact surname=Lee<br /> |Stakeholder engagement Lead organisation=Ouse and Adur Rivers Trust<br /> |Stakeholder engagement Other contact forename=Peter<br /> |Stakeholder engagement Other contact surname=King<br /> |Works and supervision Lead organisation=Environment Agency<br /> |Works and supervision Other contact forename=Lisa<br /> |Works and supervision Other contact surname=Twohig<br /> |Post-project management and maintenance Lead organisation=Ouse and Adur Rivers Trust<br /> |Post-project management and maintenance Other contact forename=Peter<br /> |Post-project management and maintenance Other contact surname=King<br /> |Monitoring Lead organisation=Ouse and Adur Rivers Trust<br /> |Monitoring Other contact forename=Peter<br /> |Monitoring Other contact surname=King<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Barriers to fish migration, Flood risk management, Impoundments (not hydropower),<br /> |Hydromorphological quality elements=Quantity &amp; dynamics of flow, Freshwater flow regime, Width &amp; depth variation, <br /> |Biological quality elements=Fish: Abundance, Fish: Species composition, Invertebrates: Abundance, <br /> |Other motivation=In-channel and Riparian habitat improvements<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Alteration in channel dimensions, Bank improvement, Weir removal, Reintroduction of natural features i.e. meanders and gravel bed, rock ramp construction<br /> |Floodplain / River corridor=Creation of wet woodland, Control of invasive species, <br /> |Planform / Channel pattern=Creation of fish pass, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references<br /> |Link=www.therrc.co.uk/sites/default/files/files/Conference/2015/Outputs/presentations/6.1.3_ian_dennis.pdf<br /> |Description=Restoring Wandle Park - RRC Conference 2015 Presentation<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

A Tributary of the River Findhorn, it flows north through the town of Forres before entering Findhorn bay. The town of Forres has a long history of flooding from the burn, with six flood events causing serious damage to property or disruption in the last fifty years. <br /> The new Flood Alleviation Scheme (FAS) took two years to complete. It included the construction of an earth-filled embankment dam designed to allow for discharges up to 8.5 m3/s to flow through Forres, with excess floodwater temporarily stored behind the dam. <br /> <br /> In addition to this, the upstream storage area has been designed to create an extensive natural sediment accretion zone (for sand, gravel and large wood). This will reduce the risk of sediment or other debris blocking the dam control structure. The scheme also aimed to create a mosaic of river and floodplain habitats, by working with natural processes to develop a multi-thread (anabranched) system. <br /> This was achieved by breaching the existing embanked channel which ran around a field boundary at two points, allowing flow to spill out across the open field, before re-joining the original channel just upstream of the dam. Tress were planted across the site to create a wet woodland habitat. <br /> <br /> Since construction in 2008 the scheme is effectively storing large wood and sediment, with a large sediment outwash fan forming at the upstream breach. A small amount of adaptive management has been required at the upstream breach due to erosional events interacting with woody material in the channel.

As a result, the rivers do not provide the full range of habitats expected and fish populations are not as good as they could be. Two hundred years on, the River Ouse and Adur catchment was selected as one of 10 Environment Agency-led pilot catchments in which to test different approaches for partnership working under the new Catchment Based Approach (CaBA) to collaborative Water Framework Directive (WFD) implementation. <br /> <br /> The £1 million MORPH project, which was funded through the Catchment Restoration Fund, was established to deliver significant improvements to the ecology of the catchment by renaturalising the watercourse and reversing the impact that historical modifications have had on the catchment. <br /> The project had two main aims:<br /> * To implement the objectives of the WFD by improving fish passage and the hydromorphology of the river.<br /> * To implement natural flood management actions identified within the River Ouse Catchment Flood Management Plan, by increasing floodplain water storage to alleviate flooding downstream.<br /> <br /> In order to deliver these aims, the project has so far:<br /> * Removed a redundant weir at Buxted Park, seeded gravel in the channel and allowed natural processes to operate on the river bed and banks in a controlled way.<br /> * Bypassed a second structure at Spring Meadow, creating a nature-like channel with a diverse range of habitats that is well connected to its floodplain. <br /> * Installed a rock ramp (the first of its kind in the UK) to allow fish to pass upstream of a culvert beneath a historic road bridge.<br /> <br /> The river restoration works have renaturalised the river and delivered significant benefits for the ecology of the river and floodplain. Improving fish passage has helped priority fish species listed in the UK Biodiversity Action Plan as needing conservation action, and more natural in-channel and floodplain habitats have contributed towards delivering WFD requirements. The Buxted Park and Sheffield Park schemes have also helped to reconnect the river to its floodplain and encourage more frequent flooding, contributing to a reduction in flood risk to sensitive areas downstream. <br /> <br /> In addition to these tangible on-the-ground achievements, the project has demonstrated that catchment partnerships can be extremely successful in delivering considerable results in a short period of time. This has galvanised local support, resulting in volunteers planting a wet woodland and other landowners actively exploring river restoration opportunities.<br /> |Monitoring surveys and results=The project is regarded by the partnership and other organisations as being extremely successful. Key evidence of this success includes:<br /> <br /> * alongside fisheries surveys, botanical and invertebrate surveys, the partnership is U. The geomorphological surveys have highlighted minor adjustments that demonstrate that natural processes are operating as intended. H, it is provide of the ecological<br /> * The project has enabled a sustainable partnership to be established between the different organisations that have been involved. The partnership continues to be very strong, with an established group of volunteers and several landowners (including the National Trust) expressing a strong interest in undertaking river restoration with the wider partnership on their land. The project team consider this to be an important indicator of a successful project. <br /> * The MORPH project was the winner of the Professional Category in the prestigious Wild Trout Trust Conservation Awards 2013. In addition, the project was Highly Commended in the Sustainability and Environment Category of the Institution of Civil Engineers South East Engineering Excellence Awards 2013. This recognition by two leading independent bodies clearly demonstrates the success of the project in delivering real environmental benefits on the ground, successfully restoring natural processes, and raising the local profile of river restoration. <br /> * This recognition is also reflected in the selection of the project to be showcased at the 2013 European River Restoration Conference and the 2013 River Restoration Centre Annual Networking Conference. <br /> * Furthermore, the project has received coverage in the national press, being featured heavily in an article in the February 2014 The Environment Magazine entitled “Partnership Pays” published by the Chartered Institution of Water and Environmental Management. <br /> * The project has been a high profile project in the Sussex area, receiving coverage in the local press, local blogs and websites along with being featured on the BBC News. Articles have also been published in the Mid Sussex Times and The Sunny Times for Buxted Park.<br /> * The BBC South East Today news programme covered the project in November 2012 and held interviews with project team members at Spring Meadow, focussing on river restoration and ecology. The segment also included flyovers of the site pre-works.<br /> * The Environment Agency and Royal HaskoningDHV have been presenting elements of the project to other areas of the Environment Agency South East region promoting the team’s achievements and promoting the good design, construction and programme management achievements.<br /> * Tand project implementation, .<br /> |Lessons learn=One of the key challenges of working at a catchment scale was rationalising catchment-wide WFD pressures and prioritising actions so that the greatest environmental and social benefits could be progressed. As in any catchment with a wide range of stakeholders, it has also been a great challenge to ensure that environmental requirements are balanced with the needs of local stakeholders. We have been able to overcome these challenges by working closely with stakeholders and developing a strategic plan which determines priorities and identifies “quick win sites” where limited constraints can allow construction to be progressed within a limited funding window.<br /> <br /> keyfor OARTthe<br /> The key lessons learned while addressing these challenges and delivering the project include:<br /> * The most important lesson is that pre project work in getting public and focused stakeholder support is vital in achieving the objectives. By working closely with landowners and other stakeholders at the beginning, listening to their concerns and incorporating these into initial designs, the projects run smoothly and at a faster pace as there is agreement right from the start.<br /> <br /> Effective partnership working can enable delivery in a short time when funding is secure. On the ground input from the OART catchment officer has greatly assisted the Environment Agency in building and maintaining partnerships.<br /> * The phased approach to design and construction allows lessons and best practice to be shared across sites. This ensures that the projects successfully deliver maximum benefits in an efficient and effective way. <br /> * Ensuring that the projects deliver wider environmental and social objectives has helped to guarantee the success of the project and maintain widespread support. <br /> * There is a clear requirement to manage stakeholder expectations through the project implementation stage so they are not surprised when sites get temporarily messy during construction. <br /> * Investment at the quick win sites has acted as a catalyst to encourage other groups to undertake improvement works at different sites in the catchment.<br /> <br /> The lessons learnt from these projects will be used by the Environment Agency and OART to guide their future catchment restoration activities in the Ouse and Adur catchments. The lessons can also be applied to other catchments as part of the Environment Agency’s Catchment Based Approach to WFD implementation.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Uck Updtream of Buxted<br /> }}<br /> {{Site<br /> |Name=Middle Ouse<br /> |WFD (national) typology=Lowland, <br /> |Pre-project morphology=Straightened, <br /> |Heavily modified water body=Yes<br /> |Site designation=UK - Areas of Outstanding Natural Beauty<br /> |Local site designation=UK - Site of Special Scientific Interest, <br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> |Dominant substrate=Clay, <br /> |River corridor land use=Agriculture (Arable), Improved/semi-improved grassland/pasture, Broadleaf/mixed woodland (semi natural), Ancient woodland, Rough unimproved grassland/pasture, Urban, <br /> |Average bankfull channel width category=2 - 5 m<br /> |Average bankfull channel depth category=2 - 5 m<br /> }}<br /> {{Project background<br /> |Project started=2011/12/01<br /> |Works started=2012/07/09<br /> |Total cost category=100 - 500 k€<br /> |Investigation and design Lead organisation=Royal HaskoningDHV<br /> |Investigation and design Other contact forename=Alex<br /> |Investigation and design Other contact surname=Lee<br /> |Stakeholder engagement Lead organisation=Ouse and Adur Rivers Trust<br /> |Stakeholder engagement Other contact forename=Peter<br /> |Stakeholder engagement Other contact surname=King<br /> |Works and supervision Lead organisation=Environment Agency<br /> |Works and supervision Other contact forename=Lisa<br /> |Works and supervision Other contact surname=Twohig<br /> |Post-project management and maintenance Lead organisation=Ouse and Adur Rivers Trust<br /> |Post-project management and maintenance Other contact forename=Peter<br /> |Post-project management and maintenance Other contact surname=King<br /> |Monitoring Lead organisation=Ouse and Adur Rivers Trust<br /> |Monitoring Other contact forename=Peter<br /> |Monitoring Other contact surname=King<br /> }}<br /> {{Motivations<br /> |Specific mitigation=Barriers to fish migration, Flood risk management, Impoundments (not hydropower),<br /> |Hydromorphological quality elements=Quantity &amp; dynamics of flow, Freshwater flow regime, Width &amp; depth variation, <br /> |Biological quality elements=Fish: Abundance, Fish: Species composition, Invertebrates: Abundance, <br /> |Other motivation=In-channel and Riparian habitat improvements<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Alteration in channel dimensions, Bank improvement, Weir removal, Reintroduction of natural features i.e. meanders and gravel bed, rock ramp construction<br /> |Floodplain / River corridor=Creation of wet woodland, Control of invasive species, <br /> |Planform / Channel pattern=Creation of fish pass, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

The River Lossie drains an area of approximately 270km² to the sea at Lossiemouth. Flooding in Elgin is not a new problem. Around twenty flood events have been recorded since 1750, with 11 floods in the last 50 years. Most recently Elgin flooded in 1997, 2000, 2002, 2009 and 2014.&lt;/p&gt;<br /> &lt;p&gt;Until recently, during major flood events, key transport links that serve the north east of Scotland have been severed. In 1997 and 2002, the A96 trunk road was closed for more than 48 hours, whilst the Inverness to Aberdeen railway line suffered considerable damage and was closed for several weeks. Flooding has caused great disruption and distress to the community of Elgin. In 2002 over 200 households were evacuated and 10 people had to be airlifted to safety; while the number of flooded homes and businesses was substantially greater.&lt;/p&gt;<br /> &lt;p&gt;The Elgin Flood Alleviation Scheme (FAS) is the single largest to be promoted in Scotland to date. The scheme is designed to provide a current-day standard of defence of 1 in 200 years. The preferred scheme for Elgin was selected on 25 February 2004. A Flood Prevention Order was publicised in October 2007 and a planning application submitted in January 2008. Scottish Ministers confirmed the scheme in December 2010, with construction starting in April 2011. Construction is due to complete in 2015. The scheme protects around 750 residential properties and 250 businesses.&lt;/p&gt;<br /> &lt;p&gt;The scheme includes:&lt;br&gt;<br /> • The restoration of an expansive blue/green corridor through Elgin reflecting both the historic and natural setting of the watercourse.&lt;br&gt;<br /> • The creation of a two-stage channel within the flood corridor, through the centre of the town, by floodplain lowering allowing flood flows to pass safely through Elgin.&lt;br&gt;<br /> • The creation of a new flood relief channel opposite Elgin Cathedral and a new natural channel to move the Tyock confluence approximately 1.5km downstream to address flood risk in New Elgin.&lt;br&gt;<br /> • Setting back flood embankments and flood walls from Glen Moray Distillery in the west to the new confluence of the Tyock/Linkwood diversion channel with the River Lossie in the east.&lt;br&gt;<br /> • Replacement and construction of three bridges to increase flood resilience and improve access.

The River Lossie drains an area of approximately 270km² to the sea at Lossiemouth. Flooding in Elgin is not a new problem. Around twenty flood events have been recorded since 1750, with 11 floods in the last 50 years. Most recently Elgin flooded in 1997, 2000, 2002, 2009 and 2014.&lt;/p&gt;<br /> &lt;p&gt;Until recently, during major flood events, key transport links that serve the north east of Scotland have been severed. In 1997 and 2002, the A96 trunk road was closed for more than 48 hours, whilst the Inverness to Aberdeen railway line suffered considerable damage and was closed for several weeks. Flooding has caused great disruption and distress to the community of Elgin. In 2002 over 200 households were evacuated and 10 people had to be airlifted to safety; while the number of flooded homes and businesses was substantially greater.&lt;/p&gt;<br /> &lt;p&gt;The Elgin Flood Alleviation Scheme (FAS) is the single largest to be promoted in Scotland to date. The scheme is designed to provide a current-day standard of defence of 1 in 200 years. The preferred scheme for Elgin was selected on 25 February 2004. A Flood Prevention Order was publicised in October 2007 and a planning application submitted in January 2008. Scottish Ministers confirmed the scheme in December 2010, with construction starting in April 2011. Construction is due to complete in 2015. The scheme protects around 750 residential properties and 250 businesses.&lt;/p&gt;<br /> &lt;p&gt;The scheme includes:&lt;br&gt;<br /> • The restoration of an expansive blue/green corridor through Elgin reflecting both the historic and natural setting of the watercourse.&lt;br&gt;<br /> • The creation of a two-stage channel within the flood corridor, through the centre of the town, by floodplain lowering allowing flood flows to pass safely through Elgin.&lt;br&gt;<br /> • The creation of a new flood relief channel opposite Elgin Cathedral and a new natural channel to move the Tyock confluence approximately 1.5km downstream to address flood risk in New Elgin.&lt;br&gt;<br /> • Setting back flood embankments and flood walls from Glen Moray Distillery in the west to the new confluence of the Tyock/Linkwood diversion channel with the River Lossie in the east.&lt;br&gt;<br /> • Replacement and construction of three bridges to increase flood resilience and improve access. The innovative Landshut Bridge was designed within the historic context of the area surrounding Elgin Cathedral and Pans Port providing an understated structure with high architectural merit.<br /> |Monitoring surveys and results=Integrated and science-based monitoring has illustrated positive change over the course of the project. Baseline geomorphology, ecology, and water chemistry surveying and repeat surveys during construction within and adjacent to the scheme footprint have enabled the design of the scheme to progress in a way which protects the existing characteristics of the area.&lt;/p&gt;<br /> &lt;p&gt;The scheme monitoring includes:&lt;br&gt;<br /> • Geomorphological surveys identified areas where bank protection was required and on-going monitoring will be undertaken to ensure that erosion is mitigated.&lt;br&gt; <br /> • Water chemistry sampling has proven that the water treatment feature has been successful in removing dieldrin from the Tyock Burn.&lt;br&gt; <br /> • Continued monitoring of the newly established areas of wetland, riparian and wildflower meadow planting will be required to ensure that these biodiverse habitats flourish.&lt;br&gt; <br /> • Large areas of giant hogweed and Japanese knotweed have been treated over the past seven years. On-going monitoring and action will be required to ensure that these do not return to the area.&lt;br&gt; <br /> • Bat and bird boxes will continue to be monitored and maintained as required.&lt;br&gt; <br /> • Aerial surveys will continue into the future to undertake wide scale assessments.<br /> |Lessons learn=The same integrated project team has worked on five separate flood alleviation schemes protecting four communities in Moray under the banner of Moray Flood Alleviation. These schemes represent an investment totaling £180 million over a fifteen year period. This has been key to the success of the project.&lt;/p&gt;<br /> &lt;p&gt;The project team operates a “continuous improvement” philosophy, using regular lessons learnt workshops to ensure that time and money is not wasted on avoidable mistakes in the future. Over the course of the project the team has developed a collaborative and efficient way of working. Currently the project is set to come in £10 million below budget. Four of the five schemes have been completed on time with Elgin scheduled to finish on time this year, 15 years after the start of the project. The project team has been co-located in the same open plan office throughout the scheme’s development and delivery ensuring matters are discussed easily and decisions are made quickly.&lt;/p&gt; <br /> <br /> &lt;p&gt;During the development of the design for the scheme, the implementation of the Water Framework Directive was in its infancy. Working closely with SEPA, the team were able to predict the implications of the Directive and design a scheme which complemented the requirements. Meeting with SEPA on a monthly basis has resulted in a sound relationship where issues have been discussed and resolved promptly.&lt;/p&gt; <br /> <br /> &lt;p&gt;The Elgin scheme has been shortlisted for the ACE/NCE 2015 Outstanding Achievement Award, which recognises schemes that have made a contribution to the reputation of consultancy and engineering. The team has also twice been commended by The Saltire Society at their Awards for Civil Engineering; in 2010 for the Forres FAS for a &lt;i&gt;“well managed and well executed FAS, constructed with high regard for the environment”&lt;/i&gt;, and in 2012 for the Rothes FAS for &lt;i&gt;“the co-operation, goodwill and ingenuity demonstrated by the team, coupled with the response elicited from the community.”&lt;/i&gt;&lt;/p&gt;<br /> <br /> &lt;p&gt;&lt;i&gt;“In more ways than one our community has been given a new lease of life and features have been created that complement the authentic architecture and public face of our village.”&lt;/i&gt;&lt;br&gt; <br /> Rev Bob Anderson, Rothes Parish Minister&lt;/p&gt;<br /> <br /> &lt;p&gt;&lt;i&gt;“I challenged the team to deliver flood alleviation and complement the environment.
