A 2021 geospatial dataset from the Bureau de Recherches Géologiques et Minières delineating areas exposed to flood hazard for risk prevention plans. The hazard map results from a study assessing hazard intensity, considering probability and intensity of dangerous phenomena. It includes areas protected by structures, which are still considered subject to hazard.
Use Cases
- Delineating flood-prone areas for land-use planning based on hazard zoning.
- Assessing risk for infrastructure and property based on hazard intensity levels.
- Incorporating protective structure data into hazard models based on the description of represented areas.
Strengths
- Hazard assessment considers both probability and intensity of flood events.
- Explicitly includes areas behind protective structures in the hazard analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
