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

FRM_FH_RIVER_VELOCITY_M_CC maps were produced by SEPA to meet duties under the Flood Risk Management (Scotland) Act 2009. The maps show flood risk from rivers, depicting flood extent, depth, and velocity for high (10-year), medium (200-year), and low (1000-year & 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 based on flood velocity data where available.
• Plan climate adaptation strategies based on the 200-year return period plus climate change scenario.
• Inform emergency response planning using high-probability (10-year return period) flood maps.

Strengths

• Maps are produced under a statutory duty by the Scottish Environment Protection Agency (SEPA).
• Includes multiple flood probability scenarios, including a specific climate change projection for the 2080s.
• Velocity data is presented in four distinct bands where appropriate.

Limitations

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