River Flood Maps: Hazard Extents, Depths, and Velocities for Scotland

Scottish flood hazard maps produced by SEPA under the Flood Risk Management (Scotland) Act 2009. The data shows river flood risk for high (10-year), medium (200-year), and low (1000-year) probability events, plus a 2080s climate change scenario. Maps include flood extent, depth, and velocity where appropriate.

Use Cases

• Modeling flood insurance risk based on probability and depth data.
• Planning infrastructure resilience based on projected 2080s climate change impacts.
• Assessing property development suitability based on flood extent and velocity bands.
• Calibrating hydrological models using the defined return period scenarios.

Strengths

• Maps are legally mandated, ensuring a formal production standard.
• Includes a specific future climate scenario (UKCP09 2080s high emissions 95%ile).
• Covers multiple probability levels (10, 200, and 1000-year return periods).
• Velocity data is provided in four confidence bands where appropriate.

Limitations

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