Linear flood defence

Flood risk management and land drainage activities

Activity and function

Potential hydromorphological change

Mitigation measures

Embankment

To prevent / reduce the inflow of river water to an area of low lying land

Change in surface/ground water interaction

Loss of structure and condition of the riparian zone

Change in sediment regime (rivers)

Loss of sediment transfer to the floodplain

Good Practice Vegetation Management

Modify or Enhance Structure

Manage and Restore Aquatic and Riparian Habitats

Remove Obsolete Structure

Revetment or wall

To prevent / reduce embankment erosion or to prevent / reduce the inflow of river water to an area of low lying land (often in combination with another main function such as traffic, building, navigation)

Change in surface/ground water interaction

Loss of structure and condition of the riparian zone

Loss of morphological diversity (rivers)

Change in sediment regime (rivers)

Good Practice Vegetation Management

Manage and Restore Aquatic and Riparian Habitats

Good Practice Sediment Management
