Project summary

Edit project overview to modify the project summary.

Planned objectives:
• Potential to improve conveyance and reduce sedimentation and improve the ecology of the Beverley Brook.
• Potential to undertake river restoration in areas where the Beverley Brook has previously been re-sectioned or modified, and where it currently flows through areas of open space.
• Potential to remove areas of old or redundant bank protection/structures and re-naturalise the channel banks.
• Potential to undertake habitat creation or enhancement works.

Objectives carried out (2012):
Flood and coastal risk management scheme to repair tidal sluice incorporating fish pass and reedbed.

At the lower section of Beverley Brook the flow is diverted into a series of culvert which outfall into the Thames and only 20% of the flow continues down the main channel. As a result the flows are low and there is a lot of siltation and lack of inchannel processes. Drivers: Biodiversity Action Plan, Water Framework Directive.
