Flood hazard classes for 15 municipalities in the Dordogne basin, derived from hydraulic modeling of historical and centennial flood events. The dataset was created by the Bureau de Recherches Géologiques et Minières and approved on 30 October 2013. It classifies land into red (non-constructible), dark blue (constructible with conditions for economic activities), and blue (constructible with conditions) zones based on water height and speed.
Use Cases
- Mapping flood-prone areas based on modeled water heights and speeds.
- Informing land-use planning and construction regulations using the defined hazard zones (red, dark blue, blue).
- Analyzing flood risk for specific rivers (Dordogne, Maronne, Souvigne, Sagne, Filèle, Malefarge, Ménoire, Cerou) mentioned in the description.
Strengths
- Hazard classification is based on specific hydraulic modeling for historical (1960) and centennial flood events.
- Covers a defined geographic area of 15 municipalities in the Corrèze department.
- Regulatory purpose is clearly defined for preventing risk to people and property.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2022-01-07 00:00:00; freshness should be verified.
- Row count and file format are unknown, which may limit suitability assessment.
