Flood risk mapping
Mapping defines the area at risk and should be the basis for all flood damage reduction programmes and subsequent actions. The maps often have a legal connotation in terms of zoning and other structural and nonstructural measures undertaken, so they need to be accurate and credible.
One of the key outputs of the flood risk management plans will be flood risk maps at river basin level. The purpose of a flood risk map is to:
- increase public awareness of the areas at risk of flooding
- Provide information of areas at risk by defining flood risk zones to give input to spatial planning.
- support the processes of prioritizing, justifying and targeting investments in order to manage and reduce the risk to people, property and the environment
