UK Flood Risk Planning Extents for Surface Water Under Climate Change

Three annual exceedance probability scenarios (0.1%, 1%, 3.3%) for surface water flooding in the United Kingdom, produced by the Environment Agency. The data incorporates climate change projections based on UKCP18 using the RCP 8.5 pathway for the 2070s epoch (2061-2125). These datasets are designed to indicate flood risk to land areas for long-term planning, not for assessing individual property risk.

Use Cases

• Assess regional land suitability for development based on surface water flood risk extents.
• Model long-term climate change impacts on flood risk using the RCP 8.5 scenario for the 2070s.
• Compare flood risk across different annual probability thresholds (0.1%, 1%, 3.3%).

Strengths

• Includes three defined annual exceedance probability (AEP) scenarios: 0.1%, 1%, and 3.3%.
• Incorporates climate change projections based on the latest UK Climate Projections (UKCP18) for the 2070s epoch.
• Produced by the authoritative Environment Agency for the United Kingdom.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data is explicitly not suitable for assessing flood risk to individual properties.
