RoFMS: UK Flood Risk Suitability from Multiple Sources

Environment Agency data provides a national-scale assessment of land areas at risk from combined flooding from rivers, the sea, and surface water. The dataset includes three spatial layers, with suitability information grouped into five bands indicating appropriate usage scales. This first version of the Risk of Flooding from Multiple Sources (RoFMS) is derived from existing RoFRS and RoFSW products.

Use Cases

• Assess regional flood risk exposure based on combined river, sea, and surface water sources.
• Determine appropriate map scales for planning studies based on the five-band suitability layer.
• Analyze the primary contributing source to combined flood risk using the risk contribution layer.

Strengths

• National-scale coverage of flood risk from three primary sources.
• Data is derived from existing, established Environment Agency flood risk products (RoFRS and RoFSW).
• Includes three distinct spatial datasets for risk, suitability, and contribution analysis.

Limitations

• Explicitly not suitable for property-level flood identification.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.

Provenance
