Risk Zone of the PPRN Rhone Aval: Flood Hazard Areas

A hazard map delineating areas exposed to one or more natural hazards, specifically for the Rhone Aval region. The dataset, produced by the Bureau de Recherches Géologiques et Minières, was last updated on July 31, 2020. It includes zones where hazard levels are graduated based on the probability and intensity of dangerous phenomena.

Use Cases

• Modeling flood risk and exposure based on hazard intensity levels mentioned in the description
• Informing land-use planning and development restrictions based on regulatory hazard zoning
• Assessing the impact of protective structures on hazard representation as described
• Conducting multi-hazard analysis for areas identified by specific hazard codes

Strengths

• Data is based on a formal hazard study assessing probability and intensity of phenomena
• Includes representation of areas behind protective structures, as mandated
• Last update date of 2020-07-31 is explicitly provided

Limitations

• Row count and specific file formats are unknown, limiting suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Freshness should be verified as the data is from 2020
