The River Torne Catchment Partnership is a group of stakeholders working towards the revitalisation of the River Torne to the east of Doncaster in South Yorkshire (Map 1) for people and wildlife. The Inspiring Water Action in the Torne (iWAIT) project has multiple outcomes including the restoration of 46.5ha of wet woodland – a rare and threatened priority habitat (Photo 1), natural flood risk benefits, education and community engagement. +

The River Traisen, one of the largest Danube tributaries in Lower Austria along the largest alluvial forest in Austria. However, the River Traisen is a heavily modified water body following the construction of the hydropower plant, Altenwörth, in 1976.
The regulated river is missing aquatic and terrestrial habitats that are usually found on flood plains. The connection between the river and the surrounding riparian forest is cut off. This situation leads to an unfavourable conservation status for the whole Natura 2000 site. High waters of the regulated Traisen rarely reach the surrounding habitats because of flood protection dams.
This project aimed to restore the River Traisen into a meandering river that is connected with the nearby wetlands of the Natura-2000 area of the Tullnerfeld floodplains, increasing habitats diversity and accessibility for fish.
Restoration actions involved: the (1) establishment of a meandering river to increase diversity of flow and habitats, the(2) creation of manifold structures in the water-land transition section of the river banks, the (3) creation of a floodplain along the new course of the river with frequently flooded sites, (4) to restore large-scale flooding zones and maintain the alluvial forest, connecting connect numerous floodplain, (5) construction of free passages in the river and cross-links on the floodplain area for fish and other water species. +

The River Trent rises at Kynpersley and flows through the heart of Stoke-on-Trent. It has had a chequered history and has been subjected to man-made interventions and high levels of pollution. As a consequence of this Environment Agency monitoring data shows this section of the River Trent is failing UK environmental standards for phosphate levels and the low presence of invertebrates and fish. Additionally, man-made structures within the watercourse act as barriers to habitat connectivity and prevent free passage for fish migration.
The River Trent flows through Bucknall Park, a popular recreational green space in Stoke-on-Trent. There is a partially collapsed weir within the watercourse at this site which is the last remaining barrier in the headwaters of the Trent. Removal of this weir would remove this barrier and also address health and safety concerns held by Stoke-on-Trent City Council and the Friends of Bucknall Park, a community group affiliated with the site.
In 2017 funding was provided by the Environment Agency under its Water Environment Improvement Fund to allow for the removal of this weir. The design of the scheme was carried out by Staffordshire Wildlife Trust on behalf of the Staffordshire Trent Valley Catchment Partnership. A number of partners have been involved through the design and delivery of this project and are credited below.
Summary of the Scheme Delivery Objectives
• Removal of the partially collapsed weir to restore the natural dynamic processes of the river and remove the physical barrier to aid fish passage. <br>
• Improve in channel habit by introducing woody debris which will act as a sediment trap and hold fine gravel both of which are important requirements, for example, for brown trout and brook lamprey.<br>
• Provide access to the river for local residents and visitors to be able to enjoy and reconnect to their waterways. To also allow access for local schools and other non-uniform groups to provide an educational resource.<br>
• Provide access to the watercourse for the Friends of Bucknall Park to be able to undertake RiverLife monitoring on site as part of ongoing monitoring of invertebrates.
Consents / Constraints / Other Issues
Flood risk consent was required from the Environment Agency to undertake the in channel work.
There was a very small window of time in which to complete the work as we had to avoid bird nesting season, trout spawning season plus spend the money within the required financial period of the Environment Agency. This timing meant that there was a likelihood of high water levels which may have prevented the project delivery.
Non native species. The river has been colonized by a large population of American signal crayfish. The banks also have some stands of Himalayan balsam and Japanese knotweed. The method statement and risk assessment for the scheme delivery ensured strict disinfection routines and Check, Clean, Dry to avoid the risk of accidentally spreading these species (and/or crayfish plague) to other sites.
Summary of other project benefits – social, economic, etc.
• Removal of a physical barrier has improved the habitat along a 10km stretch of the Trent <br>
• Improved access to the river for schools and non-uniform groups for educational purposes <br>
• Re-connecting local people to the river within a popular greenspace <br>
• Access to be able to undertake invertebrate monitoring with the Friends of Bucknall Park <br>
• New WFD demonstration site in Staffordshire Trent Valley Catchment area <br>
The River Wandle is located in the southeast of England. It is approximately 14km long with two sources, one at Waddon Ponds (Croydon) and the other at Carshalton Ponds (Sutton). It flowsnorth-eastthrough Croydon, Sutton, Lambeth, Merton and Wandsworth to then join the Tidal Thames.
The River Wandle runs under the Wandle Park, in the London Borough of Croydon, for approximately 350mand is only evident by the presence of two man-hole access chambers located within the park’s playing fields. The parkis located at OSgrid reference TQ31681,65563 and covers anarea of 8.5 hectares.
Wandle Park is owned and managed by Croydon Council. It is surrounded byamultitude of land-use types including residential, industrial and commercial.
The London Borough of Croydon in partnership with the Environment Agency is developing a scheme to restore the River Wandle at Wandle Park, Croydon. 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.
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.
Update (July 2015)
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.

The River Waveney through Bressingham has historically been diverted into what is colloquially referred to as the "New Cut". This linear, steep-sided channel was in much need of enhancement and following conversations with various local landowners, a scheme was put together to improve the river's form and function.
The lack of gradient through the site limits the effectiveness of restoration techniques aimed at increasing flow velocity. This is exacerbated by long-term maintenance that has seen the river routinely de-silted to a substantial depth, exceeding 1.5m in some places. Consequently the work that was undertaken aimed to increase habitat availability and diversity. Specifically, more shelter was created for fish and small in-stream organisms by constructing brushwood mattresses. Shallow berms were installed to soften the edge between the aquatic and terrestrial environment, providing an area of transitional plants to establish. In some locations a two-stage channel was formed using old spoil embankments, maintaining conveyance but increasing flow velocity at low flows.
Over the course of two weeks in October 2014 and with a budget of under £15,000, approximately 1.5km of river channel was enhanced. +

The River Wensum Restoration Strategy is a long-term project with the vision to restore all 71km of the River Wensum SSSI/SAC. The project is lead by the Environment Agency, working in partnership with a range of organisations and individuals including Natural England, the Water Management Alliance, Atkins, riparian landowners and anglers. We intend to restore the river and floodplain to a more naturally functioning ecosystem so that it can support the wildlife and fisheries typical of a Norfolk chalk stream. We aim to ensure that the river is sustainably managed to meet the needs of all river users, providing ecosystem services to benefit wildlife, water quality, water resources, flood risk management, agriculture and leisure activities.
The Wensum is a chalk river of great importance for its wildlife, as well as being a notable landscape feature of rural Norfolk. Its conservation interest is recognised nationally and internationally through its notification as a Site of Special Scientific Interest (SSSI) and Special Area of Conservation (SAC). However, the river is in unfavourable ecological condition and failing its Water Framework Directive targets due to past physical modifications for land drainage and milling. In essence parts of the river are too wide, too deep and too straightened, as well as being heavily impounded by mill structures and disconnected from its floodplain by spoil banks resulting from historical dredging.
For the first time we have looked at a whole river scale to see what action needs to be taken to restore each section of the river. The main recommendations of the strategy include narrowing the channel, restoring the gravel bed, reducing impoundment, reconnecting the floodplain, improving channel sinuosity and increasing the amount of large woody material in the channel.
Our over-arching philosophy is to implement integrated schemes that deliver multiple benefits, including river restoration, floodplain biodiversity enhancements, reduced flood risk to people and property, and improved angling and water quality. We work closely with a wide range of other projects and initiatives within the Wensum catchment to achieve these objectives.
As of March 2014 we had completed 6 major restoration schemes on the river. A total of 12.46km of river has been restored.

The River Wylye was historically dredged at Seven hatches and is over sized compared to flow. In the top part of the site, large hatches used to control flow between channels results in slow flows. Below the hatches major dredging combined with the presence of various structures downstream means the channel has no slope, little or no flow speed in summer and heavy siltation. The object of the work is to modify the channel to a more appropriate width, shape and slope, and to re-introduce woody debris resulting in increased and varied low speed and sediment movement. The works were understaken with the parterns listed above and the local stakeholders where the local landowners, tenant farmers and the fishing clubs that owned the fishing rights.
The work was completed in November 2007 and involved:
*reducing impounding effect of sluices
*narrowing channel width in suitable locations, using hazel coppice bundles and pre-planted coir
*reinstating the historic river bed to create spawning habitat and increase physical habitat diversity
*introducing large woody debris by selectively felling/pollarding non-native trees, replanting with suitable riparian species
==introduction==
The Hampshire Avon catchment is on of the most bio diverse catchments in the UK, with over 180 species of aquatic plants, 37 species of fish and a wide range of aquatic invertebrates. The river has a high input from chalk-rich water from springs in the headwaters. Therefore the catchment is a Special Area of Conservation (SAC), which is part of the Natura 2000 network. As a calcareous river, it is an important habitat for several endangered species like Atlantic salmon (Salmo salar), bullhead (Cottus gobio), brook lamprey (Lampetra planeri), sea lamprey (Petromyzon marinus) and Desmoulin’s whorl snail (Vertigo moulinsiana). The vegetation community consists of a Ranunculion fluitantis /Callitricho-Batrachion community.
Location Seven Hatches is located close to the confluence of the river Wylye and the Nadder. Several impoundments are present on the site. First it is characterized by the presence of a large radial sluices replacing the original hatches that gave this location its name. Just above the sluices, the river splits into two channels, the main Wylye also known as the ‘Union’ and the ‘Butcher Stream’. Next to the sluices, the footings of a railway bridge upstream and a tractor bridge downstream are present. A small chalk stream called Law’s Ditch flows into the Wylye below the railway crossing, but it is culverted underneath the Butcher Stream for 600 meters.
==Pressures and Drivers==
A conservation strategy has been written for the Avon River and its tributaries in 2003. In this document, the main pressures on the ecosystem of the Avon are pollution, fisheries (both commercial and recreational) and flood defence. These pressures come from a variety of drivers, namely agriculture, industry, fisheries, recreation and flood protection. Historical dredging has damaged the river ecosystem by destruction of habitats, loss of lateral connectivity, silting up of clean gravel habitats and unnatural river flows. At location Seven Hatches, the impoundments caused by the sluices, the footing of the railway bridge and the footing of the tractor bridge have resulted in siltation due to slower flows. In combination with the historical dredging, this has lead to a loss of hard bed structures, over widening of the channel and the creation of raised floodplains. The hydrological connectivity with the floodplain has been lost and the grazing pressure of livestock has damaged riparian vegetation structures and caused erosion at some sites.
==Global objectives==
The global objective of the STREAM demonstration project is to restore the River Avon Special Area of Conservation (SAC) and Special Site of Scientific Interest (SSSI) to favourable conditions while addressing wider biodiversity issues outside the protected areas. Another important objective is increasing public awareness for the importance of the river and valley as natural heritage by improving public access.
==Specific objectives==
The location of Seven Hatches had several specific objectives:
* Modify the operation of the Seven Hatches sluices, reducing height by an average of 0.15 metres, thus increasing ecological connectivity between reaches and improving upstream habitat quality.
* Restore the historic bed level and increase the heterogeneity of bed morphology in previously dredged reaches by the reclamation and re-introduction of excavated gravel/stone bed material
* Narrow overwide channels where necessary, in order to re-establish a sinuous channel of appropriate cross-sectional area with respect to present day hydrographs
* Increase the amount of large woody debris in the channel in order to increase both the availability of this habitat type and morphological diversity of the channel
* Break out and remove the tractor bridge footings and replace with a single span bridge. To remove the impounding effect of the structure
* Enhance the availability and quality of habitat for SAC species and habitats, in particular:
** Bullhead (Cottus gobio) (increased diversity of hard bed, particularly pools during winter and riffle/fast glides during summer and increased large woody debris for, particularly, juveniles)
** Brook lamprey (Lampetra planeri) (increased availability of well sorted, fine sediment in shaded, marginal areas with large woody debris for ammocoetes and gravel/sand dominated shallows <40 cm deep for spawning adults)
** Salmon parr (Salmo salar) (increased availability of coarse substrate, with overhead cover and woody debris lodged in the channel)
** Desmoulin’s whorl snail (Vertigo moulinsiana) in the marginal zone of the channel
** The Ranunculus community as a result of increased heterogeneity in velocity and bed morphology
==Measures selection==
The Seven Hatches restoration site was divided in 7 reaches. No measures were planned for reach 1 and 7. In reach 2, 4 and 6, deflectors are installed to narrow the channel. The deflector in reach 2 will be based on a D-shaped outlined with wooden stakes and then filled with brushwood. In reach 4, the deflector is made with large woody debris and in reach 6, tree deflectors are constructed. Next to the deflectors, gravels are also imported in reach 4 and trees are removed. It was planned to re-grade existing banks, but this was later cancelled due to the limited machine access and minimal effect on the hydrology. Fences are used to prevent grazing of the banks by livestock. Native trees are planted to compensate for the removal of unsuitable tree species. It was planned to replace the tractor bridge, but this was later cancelled due to limited effect on the hydrology. It was planned to lower the sluices at Seven Hatches (reach 3) with an average of 0.15 meters, but this was later cancelled to protect salmon habitat upstream and fear for flooding problems in the Witton area.
==Funding==
The total costs of the project were £1 million pounds. 40% of this total costs was paid for by the European Union via LIFE subsidies. The rest of the costs were paid for by the state, a water company and 2 wild life trusts.
==Communication==
During the planning phase, the public was informed via public meetings and press releases in the newspapers and magazines. The stakeholders had to accept the concept design in the project bid and during the project there was constant contact with the stakeholders. Concerns or criticisms were investigated and the project changed when the criticisms were verified. At the end of the project a conference was held for all stakeholders and general public to show them the end results of the project in their area.

The River catchment was dominated by invasive non-native species, specifically American mink and Himalayan Balsam, as well as Japanese Knotweed and Giant Hogweed. Their presence in the catchment was having a significant effect not only on ecology, but also access for recreational activities such as walking and fishing.
Project objectives included:
• The identification of bankside areas affected by invasive non-native species
• Achieve catchment wide eradication of Himalayan Balsam (HB), Japanese Knotweed (JK) and Giant Hogweed (GHW)
• Maintain mink free status of the catchment (developed by the game and wildlife conservation trust) to monitor and control mink and reintroduce water voles to the River Dore
• Educate children, local community and other catchments about invasive non-native species and the River Monnow project
All sites with GHW and JK were mapped in 2007, as well as an estimation of the upper extent of HB sites on tributaries. Volunteers were used to spray and hand pulled large areas of HB which was repeated 3 or 4 times before the first frost. All HB sites were revisited several times to ensure no plants went to seed, and the control area was extended, again with the use of volunteers. After year 3 of treatments HB had been eradicated.
This process of HB eradication was rolled out catchment wide using paid contractors, with follow up by volunteers. By Autumn 2012 70km of previously effected area will have had the initial treatment phase, with 25km of the catchment now HB free.
GNW and JK was sprayed in the spring and treated in the autumn annually, however these were not widespread in the catchment.
Costs for the last three years of work amount to £60,000 with 4,600 paid-for man hours and 1,200 voluntary hours. This equates to a figure so far of £822 per kilometre with an effort of 87 man hours per kilometre. Two more years of work are estimated (mainly hand-pulling and largely by volunteers), which would add a further 20% to those figures.
The project has been funded by Environment Agency, Natural England and Tidy Towns Wales. Generous private donations from fishery owners and fund-raising by the association has added to the project budget.
Mink have been monitored by volunteers, with captured numbers reducing to just 5 in 2007. Volunteers also annually monitor areas where water voles have been reintroduced, numbers and range are increasing.
Two schools have been introduced to “the joys of Mayfly in the classroom”, to introduce children to the importance of healthy rivers and the connection between fishing and conservation.
Produced and erected 100 signs on footpaths identifying the problem of Himalayan Balsam.
By 2014 the project aims to have eradicated Himalayan Balsam from the catchment. Natural bankside vegetation is already re-established in many areas, significantly reducing erosion and sediment release.
The Roer river forms a potential habitat for fish species that migrate between the Meuse and the Roer. The Dutch section of the Roer also forms a route for fish that migrate between the North Sea and the Meuse to their spawning.
The main aim of the project was to facilitate improved habitat access and migratory conditions in the Roer Delta for Atlantic salmon (Salmo salar) and other Annex II species, namely asp (Aspius aspius), bullhead (Cottus gobio), river lamprey (Lampetra fluviatilis), brook lamprey (Lampetra planeri), sea lamprey (Petromyzon marinus), bitterling (Rhodeus sericeus susbsp. amarus)and weatherfish (Misgurnis fossilis).
A new fish ladder was built in Roermond and the existing fish ladder at Hambeek was improved to increase its effectiveness. These two structures overcome the last remaining obstacles for fish migration between the river Meuse and the Dutch part of the river Roer, thus opening up an improved migratory route for fish from the North Sea to Germany.
Monitoring has confirmed that three of the species targeted by the project (salmon, sea lamprey and European bullhead are using the new Roermond fish ladder. Salmon and sea lamprey have also been recorded using the improved Hambeek migratory facilities and ongoing monitoring by the beneficiary will continue to measure the project’s long term impact on fish populations in the Roer. +
The Rookhope Burn is in the North Pennine orefield, and mining has been carried out in the valley for over 200 years - mainly for lead and fluorspar along with small deposits of copper and iron. This has left a legacy of mine water drainage adits and spoil heaps throughout the area. The last working fluorspar mine in the north of England, at Grove Rake, closed in 1999. In 2007, a new mine water breakout occurred, thought to be due to a blockage within the Tail Race level, which drains the abandoned mines further up the valley. This caused a large hole and a new discharge near to the old Rispey mine.
Water quality monitoring by the Environment Agency found there were high concentrations of cadmium, lead and zinc in the Rookhope Burn where it joins the River Wear. These high metal levels damage river life (insects and fish) and exceed the Environmental Quality Standards (EQS) for the Rookhope Burn, meaning that the watercourse isn't achieving the 'good status' for water quality that is set out in our Northumbria River Basin Plan. We found there are inputs of metals from disused adits and diffuse sources along the whole length of the Rookhope Burn but the largest single source is from the new breakout, which if cleaned up could improve over 8km of river. Fish surveys carried out by the Environment Agency in 2009 found reasonably good numbers of brown trout in the upper reaches of the Rookhope Burn and downstream of Rookhope Village but very poor numbers in the middle section - this was attributed to the impact of the Rispey mine discharge.
We're continuing to investigate and monitor the water quality in the Rookhope Burn, and with funding from Defra we set up a partnership with the Coal Authority and the North Pennines Area of Outstanding Natural Beauty Partnership (AONB) to look at options for removing the metals from the Rispey discharge to improve the water quality of the watercourse. Newcastle University are carrying out trials of treatment technologies which we could use to remove the heavy metals from the Rispey discharge, preventing the problem at the source and helping the Rookhope Burn to meet the EQS and return to 'good' ecological status.
• The Rookhope Burn fails its EQS for cadmium, lead and zinc.
• In times of low flow the Rispey discharge is contributing more zinc than reaches the River Wear indicating metals are being retained in the river sediments.
• When the river flows increase, a greater load of metals reaches the end of the catchment than enters the Rookhope Burn from the Rispey discharge. Additional metals are being washed into the river from mining spoil by rainfall, and from mobilising the metals previously retained within the river sediments.
• Treating the mine water discharge to remove the metals could enable 8km of river to pass the EQS and help the waterbody improve to good ecological and chemical status.
Impact of the minewater discharge
• Length of watercourse affected is 8km (one water body)
• Average metal concentration: Zinc 1.5 mg/l
Cadmium 1.5 ug/l
• Average flow 35 l/sec
• Load of zinc discharged per annum 1.5 Tonnes
• Water body ecological status is Moderate
Benefits of remediation
• The River Wear will be protected from a major pollution source
• We are using compelling evidence to drive our decisions
• We are developing partnerships with important stakeholders and using our position as an influential advisor to deliver shared environmental outcomes
• Contribute towards achieving Good Ecological and Chemical status
• 1.5 Tonnes of zinc would be prevented from entering River Wear every year

The SCRIP project is a partnership that will use CRF funds to manage restoration work to deliver habitat improvements on the rivers that drain South Cornwall and the St Austell bay area. The partnership, led by the Westcountry Rivers Trust, has been carrying out river restoration and addressing the causes of Water Framework Directive issues together for many years.
Through restoration work, the project will address issues including:
*flow modifications and habitat degradation;
*diffuse pollution from agriculture;
*barriers to fish migration;
*interrupted conveyance of river gravels reducing spawning habitats for salmonids;
*impacts from china clay extraction and historic mining
'''Description of Works
To tackle issues in the South Cornwall and St Austel Bay area, the SCRIP project will manage delivery of the following activities:
* Weir & Culvert Easements – Direct physical action to improve the connectivity of the river for multiple migrating species (fish and/or eels), therefore removing the factor that is causing the waterbody to fail for fish;
* Habitat creation – Creation of in-stream flow deflectors to create riffle/pool sequences in the long channelised section of river which lack habitat heterogeneity
* Gravel introduction - Restoration of fish spawning habi- tat by means of gravel intro-duction will increase spawning rates, and sur-vival of the early stages of salmonid and other fishes life cycle
* Fencing – Where agricultural input is a causative issue of failure under WFD (phosphate), target-ed riparian fencing along with associated drinking points will be constructed by working with key farmers and landowners within the catchment. There are multiple benefits which include reduced poaching of banks caused by livestock, it also allows a patchwork mosaic of different riparian habitat growth (when done well). Fencing also acts as a partial capture system to in- cept land and road run off and increases in stream ecological diversity.
* Culvert mitigation - Culverts to be adjusted to improve river continuity including bed load and mi-gratory fish.
* Nutrient management – Soil tests will be available for farmers in key catchments to help reduce diffuse pollution and phosphate loss and improve nutrient management on farm.
* Interpretation/Geocache - Boards-Interpretation areas will be installed to disseminate information and engage and educate local users
'''What will success look like?
Success in the rivers of South Cornwall will include the direct delivery of the above WFD targeted actions but will also include the development of a strong partnership that brings together local communities and encourages them to take pride and ownership of the issues affecting the catchment they live in. By promoting this awareness and ensuring that the local community understands their de-pendence on these natural resources, we aim to ensure the project is not only successful in the short term, but will be sustainable and continued into the future.
