Flood Hazard Zones for the Charente River in Fontcouverte, France

Hazard maps from a French flood risk prevention plan detail zones exposed to overflow from the Charente River. The maps, produced by the Bureau de Recherches Géologiques et Minières, result from a study assessing hazard intensity and probability at each point. They include areas protected by structures, which are still considered at risk, and were last updated in September 2021.

Use Cases

• Model flood risk for property development based on hazard intensity zoning
• Plan emergency response routes based on graduated hazard level maps
• Assess the adequacy of protective structures based on their representation in hazard zones
• Integrate multi-hazard exposure analysis for areas identified with codes for multiple risks

Strengths

• Hazard zones are based on a synthesis of calculated, modelled, or observed data
• Includes areas behind protective structures, accounting for potential failure

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
