All about Flood Defences
Flood defences include walls, dams, embankments and wetlands that help control rising water. Good planning protects homes and farms from flooding.
Wetlands can absorb floodwater naturally.
Some flood defences work by holding water back, while others guide it safely away. Natural features such as marshes and forests can also slow the flow of water, which makes flood defences more effective and better for wildlife.
