Wales Flood Map: Areas Benefiting from Flood Defences

Wales is the geographic scope of this spatial dataset showing areas that could be affected by flooding from rivers or the sea. It includes flood defences and the areas that benefit from them during a 1 percent fluvial or 0.5 percent tidal flood event. The dataset is produced by the Government Digital Service and has been archived, replaced by a newer version.

Use Cases

• Assess community flood risk based on the areas benefiting from flood defences.
• Plan urban development and infrastructure by identifying zones protected from 1% fluvial flood events.
• Model coastal flood impact scenarios using the 0.5% tidal flood event layer.
• Raise public awareness of flood likelihood using the spatial layers for communication.

Strengths

• Dataset is spatially explicit, designed for mapping and geographic analysis.
• Includes a specific layer for areas benefiting from flood defences during defined flood probabilities.

Limitations

• Dataset is archived and replaced, indicating it is not the current version.
• Row count, file formats, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
