The red line shows flood defences that have been built to protect against flooding from rivers and the sea. Flood defences do not remove the risk of flooding however and can be overtopped or fail in extreme weather conditions.

The defences shown provide different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales map. Flood defences that are not yet shown, and the areas that benefit from them, will be gradually added.

Further information on flood defences and the level of protection they provide will be incorporated into planned improvements scheduled for Spring 2021.
