By restoring and emulating the natural functions of catchments and rivers, flooding could be reduced.
The Chartered Institution of Water and Environmental Management will give its third presentation of Working with Natural Processes: The Evidence Behind Natural Flood Management in Edinburgh on 14 March, following events in London and Leeds.
The event will help launch the Environment Agency’s Working with Natural Processes Evidence Base, which has been developed to boost the awareness and knowledge base of flood and coastal erosion risk management authorities regarding natural flood prevention solutions.
Environmental consultant JBA Consulting has helped develop the Evidence Base which includes a new set of strategic maps that identify potential areas for WWNP across England.
These maps highlight potential areas for implementing WWNP measures based on national datasets. This could be where rivers have been disconnected from their floodplains and areas of high accumulations. These risks could then be mitigated naturally by storing water, slowing water, increasing flow connectivity between rivers and floodplains, or increasing soil infiltration and storage.
More specifically, the map targets areas that would be suitable for floodplain reconnection, runoff attenuation features, gully blocking, woodland planting covering, floodplain planting, riparian planting, and planting on slowly permeable soils.
