Flood Hazard Zones for Crazannes, France from the Charente River

PPRN hazard zone flooding data details areas exposed to overflow hazards from the Charente river in the commune of Crazannes, Charente-Maritime. The dataset is produced by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on 2021-09-17. It represents a graduated zoning of hazard levels based on the probability and intensity of flooding phenomena.

Use Cases

• Risk assessment for property development based on the graduated hazard zoning.
• Emergency preparedness planning based on the delimitation of areas exposed to overflow hazards.
• Environmental impact studies based on the synthesis of calculated, modelled, or observed hazard data.
• Regulatory compliance checking for construction in areas with specific hazard prescriptions.

Strengths

• Data is based on a formal hazard study assessing probability and intensity, as described.
• Includes areas protected by structures, representing a conservative risk assessment.
• Produced by the authoritative geological and mining research bureau (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 spatial resolution are unknown, which may limit suitability assessment.
