Description
National Flood Hazard and Risk Maps for Wales, created to comply with EU Directive 2007/60/EC and the Flood Risk Regulations (2009). The maps cover three flooding sources—rivers, the sea, and surface water—and categorize risk to people, economic, and environmental receptors at a community scale. The dataset was published by the Government Digital Service under the OGL-UK-3.0 license.
Use Cases
Assess community-scale flood risk to people, economic assets, and the environment based on the three defined flooding sources.
Compare flood risk probability thresholds (e.g., 1 in 30 year for high risk) between river, sea, and surface water sources.
Inform regional flood risk management strategies based on the aggregated risk categories described.
Study the application of EU flood directives (2007/60/EC) in national mapping efforts.
Strengths
Maps are based on three distinct flooding sources: rivers, the sea, and surface water & small watercourses.
Risk is categorized into High, Medium, and Low based on specific Annual Exceedance Probability thresholds (e.g., 1 in 30 year for high river risk).
Risk information is aggregated and displayed for three receptor categories: People, Economic, and Environment.
Limitations
The description explicitly states the maps have no official status for Planning or Insurance purposes and advises using more up-to-date sources.
