Background

Through its Flood and Coastal Erosion Risk Management Research and Development Programme, the Environment Agency has funded the development of a new design of self-regulating tide gate (SRT). This new, patented SRT helps to restore intertidal habitats behind flood embankments. These help to reduce / reverse the decline in important habitats, whilst maintaining flood protection to people and property.

Approach

This report provides information on two case studies and describes how the first installation operated in its first year. It shows how the design was adapted to suit the second site following the first trial and how the design could be adapted to suit other sites. It also describes how the new designs meet the original criteria set out for the project. It helps users decide whether a SRT should be considered when they are creating or improving an intertidal habitat.

This report is intended for:

  • Environment Agency staff
  • local authority staff
  • landowners
  • environmental bodies - the National Trust, Natural England, the RSPB and internal drainage boards (IDBs).

This project ran from 2007 to 2012.
