Flood Prevention Plan Hazard Zones for the Vienne River Downstream, Antran Area

BUREAU DE RECHERCHES GÉOLOGIQUES ET MINIÈRES provides geospatial data delineating flood hazard zones for the Vienne River downstream near Antran and Port-de-Pile. The dataset, last updated on 2021-09-16, represents the regulatory hazard map used for risk analysis in the Flood Prevention Plan (PPRI/PPRN). It includes areas exposed to flood hazards, graduated by intensity and probability, and incorporates zones behind protective structures.

Use Cases

• Modeling flood risk exposure for properties based on hazard intensity zoning.
• Informing land-use planning and development restrictions based on regulatory hazard maps.
• Validating hydrological models using synthesized hazard data from multiple calculated and observed sources.
• Assessing the impact of protective structures on hazard classification for emergency preparedness.

Strengths

• Data is based on a formal hazard study synthesizing multiple sources of calculated, modelled, or observed data.
• Includes areas protected by structures, representing them as subject to hazard to account for potential failure.
• Hazard zoning is graduated according to the level and probability of the dangerous phenomenon.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-09-16 00:00:00; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
