The Loire Valley's Val de Briare area in France is covered by this dataset of zones exposed to natural hazards, used for risk prevention plans (PPR). The dataset was published by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated in September 2021. It represents a synthesis of hazard studies, mapping areas according to the probability and intensity of dangerous phenomena, including zones behind protective structures.
Use Cases
- Modeling flood risk exposure for infrastructure planning based on hazard intensity zoning.
- Assessing the adequacy of existing protective structures based on their representation in hazard zones.
- Delineating areas for regulatory land-use prescriptions based on multi-hazard analysis.
Strengths
- Hazard zones are defined by a formal study assessing probability and intensity of phenomena.
- Includes areas behind protective structures, accounting for potential failure scenarios.
- Published by a recognized geological and mining research bureau (BRGM).
