PPRi MOSELLE AVAL: Flood Hazard Zones for Risk Prevention Plans

Hazard zones for the Moselle Aval area, representing areas exposed to one or more hazards as defined for French Risk Prevention Plans (PPR). The dataset was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated on May 11, 2021. It includes zones protected by structures, which are still considered subject to hazard, and excludes areas where the hazard study concluded the risk is zero or insignificant.

Use Cases

• Modeling flood risk exposure based on hazard intensity and probability zoning.
• Land-use planning and regulation based on multi-hazard zone identification.
• Assessing the impact of protective structures on hazard representation.
• Integrating hazard data with other geospatial layers for environmental analysis.

Strengths

• Data is derived from a synthesis of multiple calculated, modeled, or observed hazard sources.
• Explicitly includes areas behind protective structures, acknowledging residual risk.
• Last update date (2021-05-11) is provided.

Limitations

• Row count and file size are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-05-11 00:00:00; freshness should be verified for current applications.
