Approved on 30/10/2013, this dataset contains flood hazard classes for the Dordogne river basin and its tributaries in the Corrèze department of France. It was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and covers 15 municipalities, including Argentat-sur-Dordogne and Monceaux-sur-Dordogne. The hazard mapping is based on modeling, using historical floods and calculated centennial events to define water height and flow velocity classes.
Use Cases
- Land-use planning and zoning based on flood hazard classes (red, dark blue, blue) defined in the regulation.
- Risk assessment for properties and infrastructure based on modeled water heights and flow velocities.
- Historical flood analysis by comparing the modeled reference floods (e.g., October 1960 event) with current conditions.
Strengths
- Hazard mapping is based on specific hydrological modeling for the Dordogne basin and its tributaries.
- The regulatory scope is clearly defined, covering 15 specific municipalities in Corrèze.
- The dataset references specific historical and calculated flood events (e.g., October 1960 flood, centennial flood).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2022-01-14 00:00:00; freshness should be verified.
- Row count and file format are unknown, which may limit suitability assessment.
