Flood zones in prescribed Natural Risk Prevention Plans (PPRNs) and Flood Risk Prevention Plans (PPRIs) for the Haute-Garonne department. The dataset conforms to the COVADIS standard with exceptions, consolidating flood hazards from all prescribed PPRs into a single departmental file. It was last updated on 2022-01-11 by the Bureau de Recherches Géologiques et Minières.
Use Cases
- Assess flood risk for property development based on prescribed hazard zoning.
- Model potential flood damage scenarios based on hazard intensity and probability levels.
- Plan civil engineering projects and protective structures considering areas represented as subject to hazard.
- Analyze land-use regulations by comparing hazard zones with 'no or insignificant hazard' areas excluded from the dataset.
Strengths
- Consolidates flood hazards from all prescribed PPRs in the Haute-Garonne department into a single file.
- Conforms to the COVADIS data standard (table ALEA_PPRX), suggesting a structured format.
- Includes areas protected by structures, representing them as subject to hazard in case of failure.
