National Flood Risk Assessment
The National Flood Risk Assessment (NFRA) provides the underpinning evidence for the risk-based approach in the flood risk management plans. The NFRA considers the likelihood of flooding from rivers, the sea, and surface water, alongside the estimated impact on people, the economy, cultural heritage, and the environment.
To make best use of new techniques and available data, this assessment is reviewed every 6 years. The last NFRA was carried out in 2018.
