Preliminary Flood Risk Assessment Map for Thames River Basin District

An interactive map and supporting guidance inform flood risk understanding across the Thames River Basin District. The dataset shows the district, component river basins, coastline, and layers for land use and topography. It was produced by the Environment Agency to meet the requirements of the Flood Risk Regulations (2009) and supports the Preliminary Flood Risk Assessment for England report.

Use Cases

• Assess regional flood risk based on river basin and topography layers
• Plan land use and development considering flood hazard zones
• Model water flow and floodplain extent using topographic data

Strengths

• Includes multiple geospatial layers: river basins, coastline, land use, and topography
• Produced by the authoritative Environment Agency to meet statutory requirements
• Part of a national framework with equivalent datasets for each River Basin District

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 the Thames River Basin District
