It is this assessment that drives this restoration project. This project is funded by the Environment Agencies Catchment Restoration fund and is part of the Essex Healthy headwaters scheme. Physical earthworks are due to commence in Summer 2015.<br /> <br /> The site is an urban location and is designated as a local nature reserve. It is locally well loved, being popular with walkers, runners and cyclists. A majority of it is close mown grassland, however,there are significant wilder zones in places which are more typical of a Local Nature reserve. <br /> <br /> The main aspect of this project is to enhance the river banks by reducing erosion, poaching and silt inputs, the second is to improve riparian habitat and floristic diversity, as an added benefit there should also be an improvement in water quality produced by filtration of the newly established root network. <br /> <br /> The river banks will be restored using a mixture of bio engineering schemes including Coir rolls, willow spiling and bank re-profiling combined with Coir pallets. The Coir pallets and roles will be seeded with a combination of native species including flag iris, purple loosestrife and watermint among others. The current condition of the riverbank is floristically poor with either a monoculture of reeds, nettles or the invasive species Himalayan balsam.<br /> <br /> Whilst the project is not specifically targeted to deal with invasive species it is hoped that there will be some benefit derived from introducing increased floristic diversity and extra competition. <br /> <br /> The final major element of the project is to protect and enhance a deeply eroded section of riverbank. As this is a steep and heavily degraded slope the use of coir rolls and pallets would not be appropriate. Therefore the design solution decided on was to use willow spilling and use the spoil created from the bank reprofiling works to backfill behind the spiling. The idea is then that overtime the willow roots would bind the bank together preventing erosion and offer shading reducing river temperatures in the river over the summer months. <br /> <br /> There is some potential to enhance a wetland area, known locally as the spreads by creating a series of ponds and redirecting an existing drain. This will allow any water to be filtered and settled before entering the river. The ponds overtime will develop into fine habitat and support a number of specialist species. <br /> <br /> All the above should add up to the an overall improvement of the local Riverine habitat and an improvement in the general water quality and hydro morphological condition of the river.<br /> |Monitoring surveys and results=Fixed point photography will be used to monitor physical changes both post and pre work. In addition a baseline survey of macrophytes, invertebrates and water quality surveys – data gathered will include – turbidity, sediment, Ammonia/Dissolved Oxygen/Phosphate using field phosphate sampling equipment. This project site will be resurveyed against baseline at the conclusion of the project in 2015.<br /> |Lessons learn=There is significant Archaeological interest on the site. With an identified Roman Villa remains in the local area. This adds a significant cost element to the project. Investigations are currently underway to identify the implications for this project but this may make the pond and wetland enhancement uneconomic. Early contact with the local Archaeological unit is recommended.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Heavily eroded site at Bocking Blackwater .jpg<br /> }}<br /> {{Case study image<br /> |File name=Typical riverbank at Bocking Blackwater.jpg<br /> }}<br /> {{Case study image<br /> |File name=Wetland site at Bocking Blackwater.jpg<br /> }}<br /> {{Case study image<br /> |File name=Proposed location of pond.jpg<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Blackwater Pant<br /> }}<br /> {{Site<br /> |Name=Bocking Blackwater LNR<br /> |Heavily modified water body=No<br /> |Protected species present=No<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Reach length directly affected=450<br /> |Project started=2012/08/01<br /> |Works started=2016/08/07<br /> |Investigation and design Lead organisation=Essex Wildlife Trust<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren <br /> |Works and supervision Other contact surname=Alexander<br /> }}<br /> {{Motivations<br /> |Hydromorphological quality elements=Structure &amp; condition of riparian/lake shore zones, <br /> |Biological quality elements=Invertebrates, Macrophytes, <br /> |Physico-chemical quality elements=Specific non-synthetic pollutants, <br /> |Other motivation=Improvement of a local park and local resources<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Soft engineering solutions, Bank improvement, Channel reprofiling, Bank reprofiling, <br /> |Floodplain / River corridor=Erosion protection, Creation of backwater and ponds, Creation of wetland, <br /> |Social measures=Awareness campaigns, Citizen participation in the restoration project, Increase awareness of flood issues, <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.essexrivershub.co.uk<br /> |Description=For more information on this and other projects in Combined Essex catchment<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

The aim of all three projects is to target an improvement in the River Pant under the Water Framework Directive. <br /> <br /> Currently the river is failing under the Water Framework directive. There are a number of overriding issues in this waterbody most notably a heavily modified water body that has become disconnected from the floodplain, phosphate and diffuse pollution input, point source and fish passage. <br /> <br /> Whilst it is impossible that this project will single handedly turn around this assessment, it will along with the other projects begin to make a difference to this waterbody and start to improve it ecologically and with multi benefits such as flood alleviation seeing improvements. <br /> <br /> This is a fairly simple intervention and is focused around enhancing existing geomorphological processes such as riffle creation, and sediment deposition. Both are of major benefits to invertebrates, spawning fish and fish fry, which are arguably the key components in any river's ecosystem.<br /> <br /> We aim to improve the river by opening up an old meander bend. Historically the river would have flowed around this bend but at some point in the past this has been straightened. This has left a relict channel which is partially open at one end. This floods but only infrequently, we aim to connect at one end to allow increased wetting up. This will have a series of effects, it will promote aquatic and emergent vegetation in the derelict channel, it will provide a fish fry refuge at time of high flows and offer some flood alleviation by increasing connectivity with the floodplain and allow silt to settle out of the floodplain.<br /> <br /> In addition to the above, three pieces of woody debris will be installed which will further kick start geomorphic processes, in this case riffles, bank and bottom erosion and deposition. The woody debris allow pollutants to be filtered out, berms to be created and river flow to be more dynamic. Beyond the works on the river there will also be some hedge planting to connect up the landscape and the river and allow birds and other animals to move freely around the project site and other <br /> <br /> Work has now been consented and has received planning permission and once the bird breeding season is complete, work will commence.

Currently the River Pant is failing under Water Framework Directive for a number of reasons including diffuse pollution, fish passage, point source and physical modification. It should be noted that this area does suffer from low flows during the summer months, especially if the Abberton scheme which transfers water from the Ouse to Abberton is closed.<br /> <br /> There are some local issues with the river in this area, that are largely typical of those found elsewhere in Essex. Namely the disconnection of the river from the surrounding floodplain, this has led to a reduction in quality and type of Riparian habitat, in this case specifically wet woodland which is drying out and fen meadows which are decreasing in number and quality. Interestingly and of some note, the site at Ironbridge Farm and the surrounds are a Local Wildlife Site (LoWS) this means they have been recognised as an outstanding site in the context of Essex. Largely the site is notified for its mosaic of habitat but a key element of this is the presence of wet woodland and Fen meadow. So, besides contributing to raising the WFD status of the site, it is also contributing to the rehabilitation of the LoWS in the shape of an enhanced wet woodland and and enhanced Fen meadow. <br /> <br /> In order to achieve this, a plan has been designed which will increase the seasonal inundation and flooding of the woodland and fen meadow. This will have the multi benefits of reconnecting the floodplain, reducing flooding and improving water quality. <br /> <br /> A simple pipe will be installed which has been set to a level which will not only protect low flows but achieve the desired ecological effects. The level of the pipe was calculated by taking measurements on days of known flows and supported by Mannings equation. <br /> <br /> It is hoped that the pipe level (nominally 44.30OD) will allow the site to flood 4 or 5 times during the winter months, an existing land drain will also be diverted to feed into the woodland. <br /> <br /> In addition to the installation of a pipe there will also be some limited earthworks to help the water move around the site in an effective manner and also to provide further enhancement of the local wildlife site. There will be around 15 to 20cm's taken off the existing field surface to delineate a channel and hold water. The spoil created by this will then be used to create a small bund which will stop any uncontrolled water spreading across the floodplain. <br /> <br /> A number of considerations had to be considered before undertaking this work, most notably in this case the presence of trees on the site. This resulted in a number of tree assessments being undertaken in order to manage and mitigate any impact on the tree's including HERAS fencing, root protection tracks and a number of arrangements put in place to protect these trees. <br /> <br /> Work should be undertaken in August 2015, all the necessary consents are in place and a contractor has been appointed to undertake the works.<br /> |Monitoring surveys and results=A key component of this project is to rehabilitate and enhance the LoWs including Fen Meadow and Wet woodland. Therefore any monitoring will focus on any improvement is this habitat. There will also be fixed point photography, before, after and as the site develops.<br /> |Lessons learn=There are some significant limitations to Manning's equation, especially in waters that are heavily impounded as most Essex rivers are. This means that any attempts to use this equation to work out the flow and height of the water is limited, this adds a degree of complication to any water height and flow calculations. If this is the case, then water heights from specific days or contact with the local EA hydrologist is recommended to allow real time calculations to be taken at times of known flow.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Ironbridge.JPG<br /> }}<br /> {{Case study image<br /> |File name=Ironbridge Farm.JPG<br /> }}<br /> {{Case study image<br /> |File name=Ironbridge Far,.JPG<br /> }}<br /> {{Case study image<br /> |File name=River.JPG<br /> }}<br /> <br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Pant<br /> }}<br /> {{Site<br /> |Name=Ironbridge Farm<br /> |Heavily modified water body=Yes<br /> |Protected species present=No<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Reach length directly affected=250<br /> |Project started=2012/04/01<br /> |Works started=2016/08/07<br /> |Investigation and design Lead organisation=Essex Wildlife Trust<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren <br /> |Works and supervision Other contact surname=Alexander<br /> |Post-project management and maintenance Lead organisation=Essex Wildlife Trust<br /> |Post-project management and maintenance Other contact forename=Kieren <br /> |Post-project management and maintenance Other contact surname=Alexander<br /> |Monitoring Lead organisation=Essex Wildlife Trust<br /> |Monitoring Other contact forename=Kieren <br /> |Monitoring Other contact surname=Alexander<br /> }}<br /> {{Motivations<br /> |Hydromorphological quality elements=Structure &amp; condition of riparian/lake shore zones, Channel pattern/planform, <br /> |Biological quality elements=Invertebrates, Macrophytes, Fish, <br /> |Physico-chemical quality elements=Specific non-synthetic pollutants, <br /> |Other motivation=Habitat creation, Landscape enhancement,<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Habitat restoration, <br /> |Floodplain / River corridor=Creation of backwaters, BAP habitat creation, Creation of wetlands, Creation of backwater and ponds, <br /> |Planform / Channel pattern=Introduction of backwaters, Reconnect and restore aquatic habitats, <br /> |Management interventions=Ensuring biodiversity, Woodland management, Promoting riparian vegetation, <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.essexrivershub.org.uk<br /> |Description=For more information on this and other projects in Combined Essex catchment<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

All the projects are linked both thematically and geographically and are focused on improving the status of the river under the water framework.<br /> <br /> Currently the river Pant is failing under WFD, a number of issues have been identified including physical modification, fish passage and both point source and diffuse pollution. This manifests itself in a manner of ways, most notably with a heavily modified channel which has been deepened and in places straightened but most importantly disconnected from its floodplain by large artificial bunds. The land use is predominantly arable and this can lead to some pollution events both diffuse and one of such as oil and other contaminants. It should be noted that Essex and Suffolk water have done a huge amount to improve the status of this river by landowner interaction and education and this project aims to build on this.<br /> <br /> After a period of consultation and a professional assessment looking at the feasibility of the project a plan was designed to start improving the water body. This will involve installing a pipe at the mouth of an old channel, we do not know exactly know what the original purpose of this channel was but it is likely to be an old mill race that due to historical management has been increasingly separated from the original channel. However, it now offers a unique chance to reconnect the floodplain and contribute to water quality via the installation of a new 300mm culvert and simple pipe. <br /> <br /> This will allow the back channel to go from being inundated a handful of times a year to up to 15 or 16 times. This will only be transitory inundation, we are not planning on installing anything that will hold water back but it should be enough to kick start some changes in the vegetation structure promoting semi-aquatic and marginal vegetation. It will be this vegetation as it develops that allows the water to be filtered, silt will also be given the chance to settle out on the floodplain, further improving the condition of the river and its value to invertebrates and fish.<br /> <br /> In addition to the back channel connection there will also be installation of several bits of woody debris further downstream to kick start geomorphological processes in the river such as riffle creation, berms, flow dynamics and some bank erosion. It also has a part to play in diffuse pollution removal by pushing water through soil which removes nitrate via dentrification. <br /> <br /> All the consents are now in place for this project and earthworks as due to commence in August 2015, completing soon after. Once complete, we should start to see the benefits in the following winter.<br /> |Monitoring surveys and results=There will be low key monitoring surrounding this project. Fixed point photography will be utilised to monitor any changes in vegetation and land forming.<br /> <br /> There will be regular monitoring of riverflies in these reach, an improvement in these may point to an improvement in the water quality in this reach.<br /> |Lessons learn=The River Pant has low flow issues during the summer, and is also a conduit for the Ely-Ouse transfer system, these must be protected at all costs. Therefore any connection to the floodplain must take this into account. Also, due to the constraints of having to ensure that the landowner can keep access to the surrounding fields we have had to go for a formal connection, in an ideal world we would go for a more informal connection that would offer additional benefits to fish fry and avoid the need for an eel screen to prevent eels from being deposited in the new back channel.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Old derelict channel.JPG<br /> }}<br /> {{Case study image<br /> |File name=Mouth of derelict channel.JPG<br /> }}<br /> {{Case study image<br /> |File name=Heavily incised channel.JPG<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Pant<br /> }}<br /> {{Site<br /> |Name=Millfield Plantation<br /> |WFD water body code=GB105037041180<br /> |WFD water body name=Pant<br /> |Heavily modified water body=No<br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Project started=2012/04/01<br /> |Works started=2014/08/11<br /> |Investigation and design Lead organisation=Ess<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren<br /> |Works and supervision Other contact surname=Alexander<br /> |Post-project management and maintenance Lead organisation=Essex Wildlife Trust<br /> |Post-project management and maintenance Other contact forename=Kieren<br /> |Post-project management and maintenance Other contact surname=Alexander<br /> |Monitoring Lead organisation=Essex Wildlife Trust<br /> |Monitoring Other contact forename=Kieren<br /> |Monitoring Other contact surname=Alexander<br /> }}<br /> {{Motivations}}<br /> {{Measures<br /> |Bank and bed modifications measure=Creation of wooden deflectors, <br /> |Floodplain / River corridor=Floodplain reconnection, <br /> |Planform / Channel pattern=Introducing large woody debris, silt depositon on the flood plain<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.essexrivershub.org.uk<br /> |Description=For more information on this and other projects in Combined Essex catchment<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

There is a strong argument to suggest that any river restoration project must be worth the consenting process and smaller projects may not offer value for money. <br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site}}<br /> {{Project background}}<br /> {{Motivations}}<br /> {{Measures}}<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>

All the projects are linked both thematically and geographically and are focused on improving the status of the river under the water framework.<br /> <br /> Currently the river Pant is failing under WFD, a number of issues have been identified including physical modification, fish passage and both point source and diffuse pollution. This manifests itself in a manner of ways, most notably with a heavily modified channel which has been deepened and in places straightened but most importantly disconnected from its floodplain by large artificial bunds. The land use is predominantly arable and this can lead to some pollution events both diffuse and one of such as oil and other contaminants. It should be noted that Essex and Suffolk water have done a huge amount to improve the status of this river by landowner interaction and education and this project aims to build on this.<br /> <br /> After a period of consultation and a professional assessment looking at the feasibility of the project a plan was designed to start improving the water body. This will involve installing a pipe at the mouth of an old channel, we do not know exactly know what the original purpose of this channel was but it is likely to be an old mill race that due to historical management has been increasingly separated from the original channel. However, it now offers a unique chance to reconnect the floodplain and contribute to water quality via the installation of a new 300mm culvert and simple pipe. <br /> <br /> This will allow the back channel to go from being inundated a handful of times a year to up to 15 or 16 times. This will only be transitory inundation, we are not planning on installing anything that will hold water back but it should be enough to kick start some changes in the vegetation structure promoting semi-aquatic and marginal vegetation. It will be this vegetation as it develops that allows the water to be filtered, silt will also be given the chance to settle out on the floodplain, further improving the condition of the river and its value to invertebrates and fish.<br /> <br /> In addition to the back channel connection there will also be installation of several bits of woody debris further downstream to kick start geomorphological processes in the river such as riffle creation, berms, flow dynamics and some bank erosion. It also has a part to play in diffuse pollution removal by pushing water through soil which removes nitrate via dentrification. <br /> <br /> All the consents are now in place for this project and earthworks as due to commence in August 2015, completing soon after. Once complete, we should start to see the benefits in the following winter.<br /> |Monitoring surveys and results=There will be low key monitoring surrounding this project. Fixed point photography will be utilised to monitor any changes in vegetation and land forming.<br /> <br /> There will be regular monitoring of riverflies in these reach, an improvement in these may point to an improvement in the water quality in this reach.<br /> |Lessons learn=The River Pant has low flow issues during the summer, and is also a conduit for the Ely-Ouse transfer system, these must be protected at all costs. Therefore any connection to the floodplain must take this into account. Also, due to the constraints of having to ensure that the landowner can keep access to the surrounding fields we have had to go for a formal connection, in an ideal world we would go for a more informal connection that would offer additional benefits to fish fry and avoid the need for an eel screen to prevent eels from being deposited in the new back channel.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Old derelict channel.JPG<br /> }}<br /> {{Case study image<br /> |File name=Mouth of derelict channel.JPG<br /> }}<br /> {{Case study image<br /> |File name=Heavily incised channel.JPG<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Blackwater Pant<br /> }}<br /> {{Site<br /> |Name=Millfield Plantation<br /> |WFD water body code=GB105037041180<br /> |WFD water body name=Pant<br /> |Heavily modified water body=No<br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Project started=2012/04/01<br /> |Works started=2014/08/11<br /> |Investigation and design Lead organisation=Ess<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren<br /> |Works and supervision Other contact surname=Alexander<br /> |Post-project management and maintenance Lead organisation=Essex Wildlife Trust<br /> |Post-project management and maintenance Other contact forename=Kieren<br /> |Post-project management and maintenance Other contact surname=Alexander<br /> |Monitoring Lead organisation=Essex Wildlife Trust<br /> |Monitoring Other contact forename=Kieren<br /> |Monitoring Other contact surname=Alexander<br /> }}<br /> {{Motivations}}<br /> {{Measures<br /> |Bank and bed modifications measure=Creation of wooden deflectors, <br /> |Floodplain / River corridor=Floodplain reconnection, <br /> |Planform / Channel pattern=Introducing large woody debris, silt depositon on the flood plain<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.essexrivershub.org.uk<br /> |Description=For more information on this and other projects in Combined Essex catchment<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

All the projects are linked both thematically and geographically and are focused on improving the status of the river under the water framework.<br /> <br /> Currently the river Pant is failing under WFD, a number of issues have been identified including physical modification, fish passage and both point source and diffuse pollution. This manifests itself in a manner of ways, most notably with a heavily modified channel which has been deepened and in places straightened but most importantly disconnected from its floodplain by large artificial bunds. The land use is predominantly arable and this can lead to some pollution events both diffuse and one of such as oil and other contaminants. It should be noted that Essex and Suffolk water have done a huge amount to improve the status of this river by landowner interaction and education and this project aims to build on this.<br /> <br /> After a period of consultation and a professional assessment looking at the feasibility of the project a plan was designed to start improving the water body. This will involve installing a pipe at the mouth of an old channel, we do not know exactly know what the original purpose of this channel was but it is likely to be an old mill race that due to historical management has been increasingly separated from the original channel. However, it now offers a unique chance to reconnect the floodplain and contribute to water quality via the installation of a new 300mm culvert and simple pipe. <br /> <br /> This will allow the back channel to go from being inundated a handful of times a year to up to 15 or 16 times. This will only be transitory inundation, we are not planning on installing anything that will hold water back but it should be enough to kick start some changes in the vegetation structure promoting semi-aquatic and marginal vegetation. It will be this vegetation as it develops that allows the water to be filtered, silt will also be given the chance to settle out on the floodplain, further improving the condition of the river and its value to invertebrates and fish.<br /> <br /> In addition to the back channel connection there will also be installation of several bits of woody debris further downstream to kick start geomorphological processes in the river such as riffle creation, berms, flow dynamics and some bank erosion. It also has a part to play in diffuse pollution removal by pushing water through soil which removes nitrate via dentrification. <br /> <br /> All the consents are now in place for this project and earthworks as due to commence in August 2015, completing soon after. Once complete, we should start to see the benefits in the following winter.<br /> |Monitoring surveys and results=There will be low key monitoring surrounding this project. Fixed point photography will be utilised to monitor any changes in vegetation and land forming.<br /> <br /> There will be regular monitoring of riverflies in these reach, an improvement in these may point to an improvement in the water quality in this reach.<br /> |Lessons learn=The River Pant has low flow issues during the summer, and is also a conduit for the Ely-Ouse transfer system, these must be protected at all costs. Therefore any connection to the floodplain must take this into account. Also, due to the constraints of having to ensure that the landowner can keep access to the surrounding fields we have had to go for a formal connection, in an ideal world we would go for a more informal connection that would offer additional benefits to fish fry and avoid the need for an eel screen to prevent eels from being deposited in the new back channel.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Blackwater Pant<br /> }}<br /> {{Site<br /> |Name=Millfield Plantation<br /> |WFD water body code=GB105037041180<br /> |WFD water body name=Pant<br /> |Heavily modified water body=No<br /> |Protected species present=Yes<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Project started=2012/04/01<br /> |Works started=2014/08/11<br /> |Investigation and design Lead organisation=Ess<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren<br /> |Works and supervision Other contact surname=Alexander<br /> |Post-project management and maintenance Lead organisation=Essex Wildlife Trust<br /> |Post-project management and maintenance Other contact forename=Kieren<br /> |Post-project management and maintenance Other contact surname=Alexander<br /> |Monitoring Lead organisation=Essex Wildlife Trust<br /> |Monitoring Other contact forename=Kieren<br /> |Monitoring Other contact surname=Alexander<br /> }}<br /> {{Motivations}}<br /> {{Measures<br /> |Bank and bed modifications measure=Creation of wooden deflectors, <br /> |Floodplain / River corridor=Floodplain reconnection, <br /> |Planform / Channel pattern=Introducing large woody debris, silt depositon on the flood plain<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>

This manifests itself in a manner of ways, most notably with a heavily modified channel which has been deepened and in places straightened but most importantly disconnected from its floodplain by large artificial bunds. The land use is predominantly arable and this can lead to some pollution events both diffuse and one of such as oil and other contaminants. It should be noted that Essex and Suffolk water have done a huge amount to improve the status of this river by landowner interaction and education and this project aims to build on this.<br /> <br /> After a period of consultation and a professional assessment looking at the feasibility of the project a plan was designed to start improving the water body. This will involve installing a pipe at the mouth of an old channel, we do not know exactly know what the original purpose of this channel was but it is likely to be an old mill race that due to historical management has been increasingly separated from the original channel. However, it now offers a unique chance to reconnect the floodplain and contribute to water quality via the installation of a new 300mm culvert and simple pipe. <br /> <br /> This will allow the back channel to go from being inundated a handful of times a year to up to 15 or 16 times. This will only be transitory inundation, we are not planning on installing anything that will hold water back but it should be enough to kick start some changes in the vegetation structure promoting semi-aquatic and marginal vegetation. It will be this vegetation as it develops that allows the water to be filtered, silt will also be given the chance to settle out on the floodplain, further improving the condition of the river and its value to invertebrates and fish.<br /> <br /> In addition to the back channel connection there will also be installation of several bits of woody debris further downstream to kick start geomorphological processes in the river such as riffle creation, berms, flow dynamics and some bank erosion. It also has a part to play in diffuse pollution removal by pushing water through soil which removes nitrate via dentrification. <br /> <br /> All the consents are now in place for this project and earthworks as due to commence in August 2015, completing soon after. Once complete, we should start to see the benefits in the following winter. <br /> <br /> <br /> <br /> <br /> |Monitoring surveys and results=There will be low key monitoring surrounding this project.

Currently the River Pant is failing under Water Framework Directive for a number of reasons including diffuse pollution, fish passage, point source and physical modification. It should be noted that this area does suffer from low flows during the summer months, especially if the Abberton scheme which transfers water from the Ouse to Abberton is closed.<br /> <br /> There are some local issues with the river in this area, that are largely typical of those found elsewhere in Essex. Namely the disconnection of the river from the surrounding floodplain, this has led to a reduction in quality and type of Riparian habitat, in this case specifically wet woodland which is drying out and fen meadows which are decreasing in number and quality. Interestingly and of some note, the site at Ironbridge Farm and the surrounds are a Local Wildlife Site (LoWS) this means they have been recognised as an outstanding site in the context of Essex. Largely the site is notified for its mosaic of habitat but a key element of this is the presence of wet woodland and Fen meadow. So, besides contributing to raising the WFD status of the site, it is also contributing to the rehabilitation of the LoWS in the shape of an enhanced wet woodland and and enhanced Fen meadow. <br /> <br /> In order to achieve this, a plan has been designed which will increase the seasonal inundation and flooding of the woodland and fen meadow. This will have the multi benefits of reconnecting the floodplain, reducing flooding and improving water quality. <br /> <br /> A simple pipe will be installed which has been set to a level which will not only protect low flows but achieve the desired ecological effects. The level of the pipe was calculated by taking measurements on days of known flows and supported by Mannings equation. <br /> <br /> It is hoped that the pipe level (nominally 44.30OD) will allow the site to flood 4 or 5 times during the winter months, an existing land drain will also be diverted to feed into the woodland. <br /> <br /> In addition to the installation of a pipe there will also be some limited earthworks to help the water move around the site in an effective manner and also to provide further enhancement of the local wildlife site. There will be around 15 to 20cm's taken off the existing field surface to delineate a channel and hold water. The spoil created by this will then be used to create a small bund which will stop any uncontrolled water spreading across the floodplain. <br /> <br /> A number of considerations had to be considered before undertaking this work, most notably in this case the presence of trees on the site. This resulted in a number of tree assessments being undertaken in order to manage and mitigate any impact on the tree's including HERAS fencing, root protection tracks and a number of arrangements put in place to protect these trees. <br /> <br /> Work should be undertaken in August 2015, all the necessary consents are in place and a contractor has been appointed to undertake the works.<br /> |Monitoring surveys and results=A key component of this project is to rehabilitate and enhance the LoWs including Fen Meadow and Wet woodland. Therefore any monitoring will focus on any improvement is this habitat. There will also be fixed point photography, before, after and as the site develops.<br /> |Lessons learn=There are some significant limitations to Manning's equation, especially in waters that are heavily impounded as most Essex rivers are. This means that any attempts to use this equation to work out the flow and height of the water is limited, this adds a degree of complication to any water height and flow calculations. If this is the case, then water heights from specific days or contact with the local EA hydrologist is recommended to allow real time calculations to be taken at times of known flow.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Ironbridge.JPG<br /> }}<br /> {{Case study image<br /> |File name=Ironbridge Farm.JPG<br /> }}<br /> {{Case study image<br /> |File name=Ironbridge Far,.JPG<br /> }}<br /> {{Case study image<br /> |File name=River.JPG<br /> }}<br /> <br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Blackwater Pant<br /> }}<br /> {{Site<br /> |Name=Ironbridge Farm<br /> |Heavily modified water body=Yes<br /> |Protected species present=No<br /> |Invasive species present=Yes<br /> }}<br /> {{Project background<br /> |Reach length directly affected=250<br /> |Project started=2012/04/01<br /> |Works started=2016/08/07<br /> |Investigation and design Lead organisation=Essex Wildlife Trust<br /> |Investigation and design Other contact forename=Kieren<br /> |Investigation and design Other contact surname=Alexander<br /> |Stakeholder engagement Lead organisation=Essex Wildlife Trust<br /> |Stakeholder engagement Other contact forename=Kieren<br /> |Stakeholder engagement Other contact surname=Alexander<br /> |Works and supervision Lead organisation=Essex Wildlife Trust<br /> |Works and supervision Other contact forename=Kieren <br /> |Works and supervision Other contact surname=Alexander<br /> |Post-project management and maintenance Lead organisation=Essex Wildlife Trust<br /> |Post-project management and maintenance Other contact forename=Kieren <br /> |Post-project management and maintenance Other contact surname=Alexander<br /> |Monitoring Lead organisation=Essex Wildlife Trust<br /> |Monitoring Other contact forename=Kieren <br /> |Monitoring Other contact surname=Alexander<br /> }}<br /> {{Motivations<br /> |Hydromorphological quality elements=Structure &amp; condition of riparian/lake shore zones, Channel pattern/planform, <br /> |Biological quality elements=Invertebrates, Macrophytes, Fish, <br /> |Physico-chemical quality elements=Specific non-synthetic pollutants, <br /> |Other motivation=Habitat creation, Landscape enhancement,<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Habitat restoration, <br /> |Floodplain / River corridor=Creation of backwaters, BAP habitat creation, Creation of wetlands, Creation of backwater and ponds, <br /> |Planform / Channel pattern=Introduction of backwaters, Reconnect and restore aquatic habitats, <br /> |Management interventions=Ensuring biodiversity, Woodland management, Promoting riparian vegetation, <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.essexrivershub.org.uk<br /> |Description=For more information on this and other projects in Combined Essex catchment<br /> }}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

Currently the River Pant is failing under Water Framework Directive for a number of reasons including diffuse pollution, fish passage, point source and physical modification. It should be noted that this area does suffer from low flows during the summer months, especially if the Abberton scheme which transfers water from the Ouse to Abberton is closed.<br /> <br /> There are some local issues with the river in this area, that are largely typical of those found elsewhere in Essex. Namely the disconnection of the river from the surrounding floodplain, this has led to a reduction in quality and type of Riparian habitat, in this case specifically wet woodland which is drying out and fen meadows which are decreasing in number and quality. Interestingly and of some note, the site at Ironbridge Farm and the surrounds are a Local Wildlife Site (LoWS) this means they have been recognised as an outstanding site in the context of Essex. Largely the site is notified for its mosaic of habitat but a key element of this is the presence of wet woodland and Fen meadow. So, besides contributing to raising the WFD status of the site, it is also contributing to the rehabilitation of the LoWS in the shape of an enhanced wet woodland and and enhanced Fen meadow. <br /> <br /> In order to achieve this, a plan has been designed which will increase the seasonal inundation and flooding of the woodland and fen meadow. This will have the multi benefits of reconnecting the floodplain, reducing flooding and improving water quality. <br /> <br /> A simple pipe will be installed which has been set to a level which will not only protect low flows but achieve the desired ecological effects. The level of the pipe was calculated by taking measurements on days of known flows and supported by Mannings equation. <br /> <br /> It is hoped that the pipe level (nominally 44.30OD) will allow the site to flood 4 or 5 times during the winter months, an existing land drain will also be diverted to feed into the woodland. <br /> <br /> In addition to the installation of a pipe there will also be some limited earthworks to help the water move around the site in an effective manner and also to provide further enhancement of the local wildlife site. There will be around 15 to 20cm's taken off the existing field surface to delineate a channel and hold water. The spoil created by this will then be used to create a small bund which will stop any uncontrolled water spreading across the floodplain. <br /> <br /> A number of considerations had to be considered before undertaking this work, most notably in this case the presence of trees on the site. This resulted in a number of tree assessments being undertaken in order to manage and mitigate any impact on the tree's including HERAS fencing, root protection tracks and a number of arrangements put in place to protect these trees. <br /> <br /> Work should be undertaken in August 2015, all the necessary consents are in place and a contractor has been appointed to undertake the works.<br /> |Monitoring surveys and results=A key component of this project is to rehabilitate and enhance the LoWs including Fen Meadow and Wet woodland.

Currently the River Pant is failing under Water Framework Directive for a number of reasons including diffuse pollution, fish passage, point source and physical modification. It should be noted that this area does suffer from low flows during the summer months, especially if the Abberton scheme which transfers water from the Ouse to Abberton is closed.<br /> <br /> There are some local issues with the river in this area, that are largely typical of those found elsewhere in Essex. Namely the disconnection of the river from the surrounding floodplain, this has led to a reduction in quality and type of Riparian habitat, in this case specifically wet woodland which is drying out and fen meadows which are decreasing in number and quality. Interestingly and of some note, the site at Ironbridge Farm and the surrounds are a Local Wildlife Site (LoWS) this means they have been recognised as an outstanding site in the context of Essex. Largely the site is notified for its mosaic of habitat but a key element of this is the presence of wet woodland and Fen meadow. So, besides contributing to raising the WFD status of the site, it is also contributing to the rehabilitation of the LoWS in the shape of an enhanced wet woodland and and enhanced Fen meadow. <br /> <br /> In order to achieve this, a plan has been designed which will increase the seasonal inundation and flooding of the woodland and fen meadow. This will have the multi benefits of reconnecting the floodplain, reducing flooding and improving water quality. <br /> <br /> A simple pipe will be installed which has been set to a level which will not only protect low flows but achieve the desired ecological effects. The level of the pipe was calculated by taking measurements on days of known flows and supported by Mannings equation. <br /> <br /> It is hoped that the pipe level (nominally 44.30OD) will allow the site to flood 4 or 5 times during the winter months, an existing land drain will also be diverted to feed into the woodland. <br /> <br /> In addition to the installation of a pipe there will also be some limited earthworks to help the water move around the site in an effective manner and also to provide further enhancement of the local wildlife site. There will be around 15 to 20cm's taken off the existing field surface to delineate a channel and hold water. The spoil created by this will then be used to create a small bund which will stop any uncontrolled water spreading across the floodplain. <br /> <br /> A number of considerations had to be considered before undertaking this work, most notably in this case the presence of trees on the site. This resulted in a number of tree assessments being undertaken in order to manage and mitigate any impact on the tree's including HERAS fencing, root protection tracks and a number of arrangements put in place to protect these trees. <br /> <br /> Work should be undertaken in August 2015, all the necessary consents are in place and a contractor has been appointed to undertake the works.<br /> |Monitoring surveys and results=A key component of this project is to rehabilitate and enhance the LoWs including Fen Meadow and Wet woodland.

Currently the River Pant is failing under Water Framework Directive for a number of reasons including diffuse pollution, fish passage, point source and physical modification. It should be noted that this area does suffer from low flows during the summer months, especially if the Abberton scheme which transfers water from the Ouse to Abberton is closed.<br /> <br /> There are some local issues with the river in this area, that are largely typical of those found elsewhere in Essex. Namely the disconnection of the river from the surrounding floodplain, this has led to a reduction in quality and type of Riparian habitat, in this case specifically wet woodland which is drying out and fen meadows which are decreasing in number and quality. Interestingly and of some note, the site at Ironbridge Farm and the surrounds are a Local Wildlife Site (LoWS) this means they have been recognised as an outstanding site in the context of Essex. Largely the site is notified for its mosaic of habitat but a key element of this is the presence of wet woodland and Fen meadow. So, besides contributing to raising the WFD status of the site, it is also contributing to the rehabilitation of the LoWS in the shape of an enhanced wet woodland and and enhanced Fen meadow. <br /> <br /> In order to achieve this, a plan has been designed which will increase the seasonal inundation and flooding of the woodland and fen meadow. This will have the multi benefits of reconnecting the floodplain, reducing flooding and improving water quality. <br /> <br /> A simple pipe will be installed which has been set to a level which will not only protect low flows but achieve the desired ecological effects. The level of the pipe was calculated by taking measurements on days of known flows and supported by Mannings equation. <br /> <br /> It is hoped that the pipe level (nominally 44.30OD) will allow the site to flood 4 or 5 times during the winter months, an existing land drain will also be diverted to feed into the woodland. <br /> <br /> In addition to the installation of a pipe there will also be some limited earthworks to help the water move around the site in an effective manner and also to provide further enhancement of the local wildlife site. There will be around 15 to 20cm's taken off the existing field surface to delineate a channel and hold water. The spoil created by this will then be used to create a small bund which will stop any uncontrolled water spreading across the floodplain. <br /> <br /> A number of considerations had to be considered before undertaking this work, most notably in this case the presence of trees on the site. This resulted in a number of tree assessments being undertaken in order to manage and mitigate any impact on the tree's including HERAS fencing, root protection tracks and a number of arrangements put in place to protect these trees. <br /> <br /> Work should be undertaken in August 2015, all the necessary consents are in place and a contractor has been appointed to undertake the works.<br /> |Monitoring surveys and results=A key component of this project is to rehabilitate and enhance the LoWs including Fen Meadow and Wet woodland. Therefore any monitoring will focus on any improvement is this habitat.
