This dataset has now been superseded and replaced with the Flood Defence Structures dataset

This dataset shows flood defences that have been built to protect against flooding from rivers and the sea. The defences shown provide different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales (FRAW) map. Flood defences that are not yet shown, and the areas that benefit from them, will be gradually added

Flood defences do not remove the risk of flooding however and can be overtopped or fail in extreme weather conditions.
