Val de Nevers in the Nièvre department of France is the geographic scope of this dataset. It contains areas exposed to one or more natural hazards, as defined by the hazard map used for risk analysis in the Natural Flood Risk Prevention Plan (PPRi). The dataset was produced by the Bureau de Recherches Géologiques et Minières and was last updated on May 4, 2021.
Use Cases
- Model flood risk exposure based on hazard intensity and probability levels described in the dataset.
- Delineate land-use planning zones based on regulatory hazard zoning.
- Assess the impact of protective structures on hazard representation, as areas behind them are still included.
- Identify areas of 'no or insignificant hazard' for comparative analysis within the study perimeter.
Strengths
- Data is based on a formal hazard study that synthesizes multiple sources of calculated, modeled, or observed data.
- Hazard zones are graduated according to the level of hazard, providing a nuanced risk assessment.
- The dataset includes areas protected by structures, acknowledging their potential failure or inadequacy.
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.
