River Flood Maps: Flood Extent, Depth, and Velocity for Scotland

These maps show flood hazard from rivers in Scotland, produced by SEPA under the Flood Risk Management (Scotland) Act 2009. They cover three probability scenarios: high (10-year return), medium (200-year return), and low (1000-year return plus a 2080s climate change scenario). The maps likely contain flood extent, depth, and velocity data where available.

Use Cases

• Assess flood risk for property development based on flood extent and depth maps.
• Model potential flood damage based on flood velocity data.
• Plan climate change adaptation strategies based on the 2080s high-emissions scenario maps.
• Inform emergency response planning using maps of high-probability (10-year return) flood events.

Strengths

• Maps are produced under a statutory duty, suggesting an official and regulated data source.
• Covers three distinct flood probability scenarios, including a future climate change projection.
• Includes multiple hazard layers: extent, depth, and velocity where appropriate.

Limitations

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