Natural Flood Risk Prevention Plan Hazard Zones for Val de La Charité-sur-Loire, Nièvre

A 2021 geospatial dataset from the French Geological Survey delineating areas exposed to natural hazards for flood risk planning. It represents hazard zones based on a graduated analysis of probability and intensity for phenomena like flooding. The dataset includes areas protected by structures, which are still considered subject to hazard.

Use Cases

• Assessing flood risk for property development based on the graduated hazard zoning.
• Modeling potential damage from protective structure failure based on areas represented as 'always subject to hazard'.
• Prioritizing infrastructure investment based on multi-hazard exposure codes mentioned for multi-risk zones.
• Validating hydrological models against the study's synthesis of calculated, modelled, and observed hazard data.

Strengths

• Hazard assessment is based on a specific methodology for each hazard type, as described.
• Dataset explicitly includes areas behind protective structures, accounting for failure scenarios.
• Produced by the authoritative BUREAU DE RECHERCHES GÉOLOGIQUES ET MINIÈRES organization.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-05-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
