Flood zones from approved Natural Risk Prevention Plans (PPRN) and Flood Risk Prevention Plans (PPRI) in the Haute-Garonne department of France. The dataset conforms to the COVADIS standard and aggregates flood hazards from all approved plans into a single file. It was last updated on January 11, 2022, by the Bureau de Recherches Géologiques et Minières.
Use Cases
- Assess flood risk for property development based on the hazard zoning maps.
- Model potential flood damage scenarios based on hazard intensity and probability levels.
- Plan emergency response routes and infrastructure based on areas protected by structures that are still considered at risk.
- Analyze land-use regulations by comparing hazard zones with areas classified as having 'no or insignificant hazard'.
Strengths
- Aggregates flood hazards from all approved PPRs in the Haute-Garonne department into a single file.
- Conforms to the standardized COVADIS data model (table ALEA_PPRX) for interoperability.
- Explicitly includes areas protected by structures, representing them as subject to hazard.
