15 municipalities in Corrèze, France, are covered by flood hazard classifications from the 2013 PPRI (Plan for the Prevention of Natural Flood Risk) for the Dordogne basin and its tributaries. The dataset, managed by the Bureau de Recherches Géologiques et Minières, classifies land into red (non-constructible), dark blue (constructible under conditions for economic activities), and blue (constructible under conditions) zones based on hazard intensity. The hazard is derived from modeling, using historical floods for some rivers and calculated centennial floods for others.
Use Cases
- Assess flood risk for property development based on the hazard class zoning (red, dark blue, blue).
- Model potential flood damage and plan emergency responses using the hazard classification derived from flood heights and speeds.
- Analyze land-use restrictions and construction feasibility across the 15 municipalities covered by the PPRi.
- Validate or compare flood hazard models using the historical and calculated reference floods mentioned in the description.
Strengths
- Covers 15 specific municipalities in Corrèze, providing localized hazard data.
- Hazard classification is based on modeled flood heights and speeds, offering a structured risk assessment.
- Explicitly defines three regulatory land-use zones (red, dark blue, blue) based on hazard intensity.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2022-01-07; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
