Coastal Flood Maps: UK Hazard Extent and Depth for Multiple Probabilities

Coastal flood hazard maps from the Scottish Government show flood extent and depth for three probability scenarios. The scenarios include a high-probability 10-year return period, a medium-probability 200-year return period, and a low-probability 1000-year return period plus a 200-year return period with a UKCP09 high-emissions climate change scenario for the 2080s. The data was last updated on 2026-07-08.

Use Cases

• Modeling property and infrastructure risk based on flood extent and depth maps.
• Assessing future climate change impacts on coastal flooding using the UKCP09 high-emissions scenario for the 2080s.
• Informing land-use planning and policy based on high, medium, and low-probability flood events.
• Calibrating flood simulation models with observed event data referenced in the high-probability scenario.

Strengths

• Provides three distinct probability scenarios (10-year, 200-year, 1000-year return periods).
• Includes a forward-looking climate change scenario based on UKCP09 high emissions 95th percentile predictions for the 2080s.
• Maps show both flood extent and flood depth where available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-07-08).
