Flood hazard maps for Scotland produced by SEPA to meet the Flood Risk Management (Scotland) Act 2009. The maps show flood risk from rivers, including extent, depth, and velocity for high (10-year), medium (200-year), and low (1000-year and 200-year plus climate change) probability events. The climate change scenario uses UKCP09 high emissions predictions for the 2080s.
Use Cases
- Assess flood risk for property development based on flood extent and depth maps.
- Model potential flood damage and emergency response using flood velocity data.
- Evaluate long-term climate change impacts on floodplains using the 2080s high emissions scenario.
- Inform land-use planning and insurance risk assessment based on defined return period probabilities.
Strengths
- Maps include three defined flood probability scenarios: 10-year, 200-year, and 1000-year return periods.
- Includes a specific climate change projection for the 2080s based on the UKCP09 high emissions scenario.
- Hazard maps show multiple attributes where available: flood extent, depth, and velocity.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to uk_data, being specific to Scotland.
