Coastal Flood Maps for the UK with Climate Change Projections

Coastal flood hazard maps for the United Kingdom show flood extent and depth for three probability scenarios. The data includes a climate change projection for the 2080s based on the UKCP09 high emissions scenario. These maps were produced by the Government Digital Service for consistency with Scottish Planning Policy.

Use Cases

• Model flood risk for infrastructure planning based on the 10, 200, and 1000-year return period flood extents.
• Assess long-term climate change impacts on coastal zones using the 2080s high emissions scenario projection.
• Validate or calibrate hydrodynamic models using the provided flood depth and extent maps.

Strengths

• Includes three distinct flood probability scenarios (10, 200, and 1000-year return periods).
• Integrates a specific climate change projection for the 2080s using the UKCP09 high emissions model.
• Maps show both flood extent and, where appropriate, flood depth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
