Flood Hazard Zones for the Avre River in Eure-et-Loir, France

A hazard map delineating areas exposed to flooding for the Avre River in the Eure-et-Loir department of France. The dataset was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and represents the result of a hazard study assessing the probability and intensity of dangerous phenomena. It was last updated on April 3, 2019.

Use Cases

• Risk assessment for property development based on mapped flood hazard zones.
• Land-use planning and zoning regulation enforcement based on the PPRN (Plan de Prévention des Risques Naturels) framework.
• Modeling potential flood damage by overlaying hazard intensity with asset data.
• Validating hydrological models using the synthesized hazard data from multiple sources.

Strengths

• Data is the result of a formal hazard study conducted by a national geological survey (BRGM).
• Hazard zones are graduated according to the level of hazard, indicating intensity and probability.
• Areas protected by structures are included, accounting for potential failure scenarios.

Limitations

• Last updated 2019-04-03 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
