Andelle Valley Hazard Zones for Risk Prevention Plans

Hazard zones for the Andelle Valley, France, delineated by the Bureau de Recherches Géologiques et Minières. These zones represent areas exposed to one or more natural hazards, with levels graduated according to probability and intensity. The data was last updated on June 30, 2021.

Use Cases

• Assess land-use suitability based on hazard intensity levels described in the zoning.
• Model potential damage from natural hazards using the graduated hazard zones.
• Validate or update local risk prevention regulations based on the official hazard map.
• Analyze the spatial overlap of multiple hazards for multi-risk PPRs.

Strengths

• Hazard zones are defined by a formal study methodology specific to each hazard type.
• Includes areas protected by structures, which are still considered subject to hazard.
• Distinguishes between 'zero or insignificant hazard zones' and areas requiring representation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-06-30 00:00:00; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
