Flood Hazard Zones for the Charente River in Port-d'Envaux, France

Geospatial hazard zones for flooding by overflow of the Charente River in the commune of Port-d'Envaux, Charente-Maritime. The dataset was produced by the Bureau de Recherches Géologiques et Minières and last updated in September 2021. It represents areas exposed to hazard, synthesized from multiple calculated, modelled, or observed hazard data sources.

Use Cases

• Modeling flood risk and potential damage based on hazard intensity and probability levels described.
• Informing land-use planning and building regulations using the graduated hazard zoning.
• Assessing the impact of protective structures by analyzing areas represented as subject to hazard despite protections.
• Cross-referencing multi-hazard exposure where zones are identified by codes for each hazard.

Strengths

• Data is based on a formal hazard study assessing intensity and probability, as described.
• Includes areas behind protective structures, representing a conservative risk assessment.
• Produced by a recognized geological and mining research organization (BRGM).

Limitations

• Last updated 2021-09-17 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
