|Project summary=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.

|Monitoring surveys and results=For each scheme we monitor the impacts of restoration on fish, invertebrates, aquatic macrophytes, and protected species (e.g. water vole). Fixed point photography is also undertaken.

|Project summary=The River Test is a chalk stream renowned worldwide for its excellent trout fly fishing. The reaches of the Test flowing through the Bossington Estate have been dredged and impounded by weirs leaving them wide, deep and silty with resulting low velocities and poor fish stocks.

Cain Bio-Engineering Ltd. produced designs for the five reaches that flow through the Bossington Estate. In partnership with the Estate and the Environment Agency, Cain Bio-Engineering Ltd. supervised the installation, based on 450m of channel narrowing on the Old Station Beat. The restoration was constructed using a variety of techniques, including woody deflectors and gravel fronted berms.
|Monitoring surveys and results=The restored reach provides a range of flow velocities and habitats with a reported increase in wild brown trout and a reduction in the Estate’s necessity to stock. The pre and post-restoration macro-invertebrate communities have been monitored by Southampton University, with results expected in Autumn 2014.

|Project summary=The River Test is a chalk stream renowned worldwide for its excellent trout fly fishing. The reaches of the Test flowing through the Bossington Estate have been dredged and impounded by weirs leaving them wide, deep and silty with resulting low velocities and poor fish stocks.

Cain Bio-Engineering Ltd. produced designs for the five reaches that flow through the Bossington Estate. In partnership with the Estate and the Environment Agency, Cain Bio-Engineering Ltd. supervised the installation, based on 450m of channel narrowing on the Old Station Beat. The restoration was constructed using a variety of techniques, including woody deflectors and gravel fronted berms.
|Monitoring surveys and results=The restored reach provides a range of flow velocities and habitats with a reported increase in wild brown trout and a reduction in the Estate’s necessity to stock. The pre and post-restoration macro-invertebrate communities have been monitored by Southampton University, with results expected in Autumn 2014.

|Project summary=The Test and Itchen River Restoration Strategy is a collaborative project between the Environment Agency, Natural England, local fisheries and riparian owners.

Presently the SSSI status of the Test and Itchen is in unfavourable condition. This is due to historic dredging, the number of structures, industry and historic management. The aim of the Strategy is to collaboratively work with landowners to restore both rivers so that they reach favourable condition in the future.

Up to June 2014, approximately 2km has been improved by bed raising, narrowing and encouraging a change in management. Five restoration projects were completed in 2013 and a further six are planned for 2014.

Project 1: Old Station Beat restoration, River Test at Bossington (completed 2013) 
At the Bossington Estate, the Environment Agency and Natural England have worked with Cain Bio-engineering to narrow the channel considerably (up to 40-60% in some sections) to restore a more natural river which has already led to significant improvement in the variety of river bed heterogeneity and in-channel habitats observed. The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was approximately £40,000 for 450m of restoration.

Project 2: River Test, Houghton Estate, close to Stockbridge (completed 2013) 
The Houghton Club, one of the first fisheries to establish in England if not the world, has been open-minded. They agreed to modify historic bank management practices to enhance the channel and side channel scrapes have been created to reconnect the river to its floodplain in strategic areas. Selective channel narrowing has also taken place. Flooding in winter 2013/4 immediately showed the benefits of reconnecting the river with the surrounding land (which is designated SSSI). From a flood risk management perspective, holding water on this land prior to the river reaching Stockbridge was noted to have had a positive influence on flood risk reduction in the village. The project was jointly funded by the Environment Agency and the Houghton Estate.
|Monitoring surveys and results=Students at the University of Southampton are monitoring the Bossington Estate project, and are working with the Environment Agency on other sites too.
|Lessons learn=The sections of river that have been restored demonstrate the contrasting approaches of contractors working on different sites (see Image Gallery). The extent of channel narrowing and restoration works take into account varying views of the landowners, the aspirations of the fishery and the requirement to improve the SSSI.

The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was approximately £40,000 for 450m of restoration.

Project 2: River Test, Houghton Estate, close to Stockbridge (completed 2013) 
The Houghton Club, one of the first fisheries to establish in England if not the world, has been open-minded. They agreed to modify historic bank management practices to enhance the channel and side channel scrapes have been created to reconnect the river to its floodplain in strategic areas. Selective channel narrowing has also taken place. Flooding in winter 2013/4 immediately showed the benefits of reconnecting the river with the surrounding land (which is designated SSSI). From a flood risk management perspective, holding water on this land prior to the river reaching Stockbridge was noted to have had a positive influence on flood risk reduction in the village. The project was jointly funded by the Environment Agency and the Houghton Estate.
|Monitoring surveys and results=Students at the University of Southampton are monitoring the Bossington Estate project, and are working with the Environment Agency on other sites too.
|Lessons learn=The sections of river that have been restored demonstrate the contrasting approaches of contractors working on different sites (see Image Gallery). The extent of channel narrowing and restoration works take into account varying views of the landowners, the aspirations of the fishery and the requirement to improve the SSSI.

|Project summary=The Test and Itchen River Restoration Strategy is a collaborative project between the Environment Agency, Natural England, local fisheries and riparian owners.

Presently the SSSI status of the Test and Itchen is in unfavourable condition. This is due to historic dredging, the number of structures, industry and historic management. The aim of the Strategy is to collaboratively work with landowners to restore both rivers so that they reach favourable condition in the future.

Up to June 2014, approximately 2km has been improved by bed raising, narrowing and encouraging a change in management. Five restoration projects were completed in 2013 and a further six are planned for 2014.

Project 1: River Test, Bossington Estate, close to Bossington Park (completed 2013)

|Project summary=The River Test is a chalk stream renowned worldwide for its excellent trout fly fishing. The reaches of the Test flowing through the Bossington Estate have been dredged and impounded by weirs leaving them wide, deep and silty with resulting low velocities and poor fish stocks.

Cain Bio-Engineering Ltd. produced designs for the five reaches that flow through the Bossington Estate. In partnership with the Estate and the Environment Agency, Cain Bio-Engineering Ltd. supervised the installation, based on 450m of channel narrowing on the Old Station Beat. The restoration was constructed using a variety of techniques, including woody deflectors and gravel fronted berms.
|Monitoring surveys and results=The restored reach provides a range of flow velocities and habitats with a reported increase in wild brown trout and a reduction in the Estate’s necessity to stock. The pre and post-restoration macro-invertebrate communities have been monitored by Southampton University, with results expected in Autumn 2014.

|Project summary=The Test and Itchen River Restoration Strategy is a collaborative project between the Environment Agency, Natural England, local fisheries and riparian owners.

Presently the SSSI status of the Test and Itchen is in unfavourable condition. This is due to historic dredging, the number of structures, industry and historic management. The aim of the Strategy is to collaboratively work with landowners to restore both rivers so that they reach favourable condition in the future.

Up to June 2014, approximately 2km has been improved by bed raising, narrowing and encouraging a change in management. Five restoration projects were completed in 2013 and a further six are planned for 2014.

Project 1: River Test, Bossington Estate, close to Bossington Park (completed 2013) 
At the Bossington Estate, the Environment Agency and Natural England have worked with Cain Bio-engineering to narrow the channel considerably (up to 40-60% in some sections) to restore a more natural river which has already led to significant improvement in the variety of river bed heterogeneity and in-channel habitats observed. The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was £65,000 for approximately 450m of restoration.

Project 2: River Test, Houghton Estate, close to Stockbridge (completed 2013) 
The Houghton Club, one of the first fisheries to establish in England if not the world, has been open-minded. They agreed to modify historic bank management practices to enhance the channel and side channel scrapes have been created to reconnect the river to its floodplain in strategic areas. Selective channel narrowing has also taken place. Flooding in winter 2013/4 immediately showed the benefits of reconnecting the river with the surrounding land (which is designated SSSI). From a flood risk management perspective, holding water on this land prior to the river reaching Stockbridge was noted to have had a positive influence on flood risk reduction in the village. The project was jointly funded by the Environment Agency and the Houghton Estate.
|Monitoring surveys and results=Students at the University of Southampton are monitoring the Bossington Estate project, and are working with the Environment Agency on other sites too.
|Lessons learn=The sections of river that have been restored demonstrate the contrasting approaches of contractors working on different sites (see Image Gallery). The extent of channel narrowing and restoration works take into account varying views of the landowners, the aspirations of the fishery and the requirement to improve the SSSI.

|Project summary=The Test and Itchen River Restoration Strategy is a collaborative project between the Environment Agency, Natural England, local fisheries and riparian owners.

Presently the SSSI status of the Test and Itchen is in unfavourable condition. This is due to historic dredging, the number of structures, industry and historic management. The aim of the Strategy is to collaboratively work with landowners to restore both rivers so that they reach favourable condition in the future.

Up to June 2014, approximately 2km has been improved by bed raising, narrowing and encouraging a change in management. Five restoration projects were completed in 2013 and a further six are planned for 2014.

Project 1: River Test, Bossington Estate, close to Bossington Park (completed 2013) 
At the Bossington Estate, the Environment Agency and Natural England have worked with Cain Bio-engineering to narrow the channel considerably (up to 40-60% in some sections) to restore a more natural river which has already led to significant improvement in the variety of river bed heterogeneity and in-channel habitats observed. The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was £65,000 for approximately 450m of restoration.

Project 2: River Test, Houghton Estate, close to Stockbridge (completed 2013) 
The Houghton Club, one of the first fisheries to establish in England if not the world, has been open-minded. They agreed to modify historic bank management practices to enhance the channel and side channel scrapes have been created to reconnect the river to its floodplain in strategic areas. Selective channel narrowing has also taken place. Flooding in winter 2013/4 immediately showed the benefits of reconnecting the river with the surrounding land (which is designated SSSI). From a flood risk management perspective, holding water on this land prior to the river reaching Stockbridge was noted to have had a positive influence on flood risk reduction in the village. The project was jointly funded by the Environment Agency and the Houghton Estate.
|Monitoring surveys and results=Students at the University of Southampton are monitoring the Bossington Estate project, and are working with the Environment Agency on other sites too.
|Lessons learn=The sections of river that have been restored demonstrate the contrasting approaches of contractors working on different sites (see Image Gallery). The extent of channel narrowing and restoration works take into account varying views of the landowners, the aspirations of the fishery and the requirement to improve the SSSI.

|Project summary=The Test and Itchen River Restoration Strategy is a collaborative project between the Environment Agency, Natural England, local fisheries and riparian owners.

Presently the SSSI status of the Test and Itchen is in unfavourable condition. This is due to historic dredging, the number of structures, industry and historic management. The aim of the Strategy is to collaboratively work with landowners to restore both rivers so that they reach favourable condition in the future.

Up to June 2014, approximately 2km has been improved by bed raising, narrowing and encouraging a change in management. Five restoration projects were completed in 2013 and a further six are planned for 2014.

Project 1: River Test, Bossington Estate, close to Bossington Park(completed 2013)
At the Bossington Estate, the Environment Agency and Natural England have worked with Cain Bio-engineering to narrow the channel considerably (up to 40-60% in some sections) to restore a more natural river which has already led to significant improvement in the variety of river bed heterogeneity and in-channel habitats observed. The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was £65,000 for approximately 450m of restoration.

Project 2: River Test, Houghton Estate, close to Stockbridge(completed 2013)
The Environment Agency and Natural England have worked with Cain Bio-Engineering to narrow the channel considerably (up to 40-60% in some sections) to restore a more natural river which has already led to significant improvement in the variety of river bed heterogeneity and in-channel habitats observed. The Estate have supported the project as they would like to attract anglers who prefer fly fishing in a more ‘challenging’ environment, than on other sections of the middle River Test, to offer this in the Test Valley. The total cost of the scheme was £65,000 for approximately 450m of restoration.

Project 2: River Test close to Stockbridge (completed 2013)
The Houghton Club, one of the first fisheries to establish in England if not the world, has been open-minded. They agreed to modify historic bank management practices to enhance the channel and side channel scrapes have been created to reconnect the river to its floodplain in strategic areas. Selective channel narrowing has also taken place.

Flooding in winter 2013/4 immediately showed the benefits of reconnecting the river with the surrounding land (which is designated SSSI). From a flood risk management perspective, holding water on this land prior to the river reaching Stockbridge was noted to have had a positive influence on flood risk reduction in the village.
|Monitoring surveys and results=Students at the University of Southampton are monitoring the Bossington Estate project, and are working with the Environment Agency on other sites too.
|Lessons learn=The sections of river that have been restored demonstrate the contrasting approaches of contractors working on different sites (see Image Gallery). The extent of channel narrowing and restoration works take into account varying views of the landowners, the aspirations of the fishery and the requirement to improve the SSSI.

|Project summary=The Sussex River Ouse near Slaugham, West Sussex has historically been managed for navigation. These works have straightened the channel, increasing the width and depth in many places.
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.

The Sheffield Park Meanders project involved the reinstatement of the historic meandering course of the Ouse at spring meadow to achieve the following aims:

• 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.

• 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.

• The incorporation of a low flow channel which maintains sufficient water depth for fish migration in all flow conditions.

• Restoration of existing wet meadow habitats at the site and creation of new woodland areas.

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.

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.

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 & Adur Rivers Trust (OART) & 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.

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.

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.
Promotion of the project included coverage on BBC South East today programme, local papers and area group websites.
|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.
|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.

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.

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.

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) & reduce flood risk downstream by increasing capacity for floodwaters.

The public have been consulted and kept informed of progress throughout the project, building local support for river restoration and its associated benefits.

|Project summary=The Sussex River Ouse near Slaugham, West Sussex has historically been managed for navigation. These works have straightened the channel, increasing the width and depth in many places.
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.

The Sheffield Park Meanders project involved the reinstatement of the historic meandering course of the Ouse at spring meadow to achieve the following aims:

• 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.

• 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.

• The incorporation of a low flow channel which maintains sufficient water depth for fish migration in all flow conditions.

• Restoration of existing wet meadow habitats at the site and creation of new woodland areas.

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.

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.

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 & Adur Rivers Trust (OART) & 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.

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.

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.
Promotion of the project included coverage on BBC South East today programme, local papers and area group websites.
|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.
|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.

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.

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.

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) & reduce flood risk downstream by increasing capacity for floodwaters.

The public have been consulted and kept informed of progress throughout the project, building local support for river restoration and its associated benefits.
