Risk of Flooding from Multiple Sources: UK National Flood Risk Contribution

UK national-scale geospatial data indicating areas at risk of flooding from rivers, sea, and surface water. The dataset is produced by the Environment Agency using existing flood risk products and is available as GIS layers. This record has been retired, and users are directed to separate sources for current flood risk information.

Use Cases

• Assess regional flood risk from multiple sources based on the combined risk band data.
• Determine appropriate map scales for flood risk visualization based on the suitability band data.
• Analyze the primary contributing source to flood risk in an area based on the risk contribution data.

Strengths

• National-scale coverage of the UK.
• Derived from existing authoritative flood risk products (RoFRS and RoFSW).
• Provides three distinct spatial datasets for different analytical purposes.

Limitations

• Record is retired and not suitable for current analysis.
• Not appropriate for property-level assessment.
• Column-level documentation is absent; field semantics must be inferred after download.

Provenance
