Hazard zones for marine submersion defined for the Lower Bresle Valley's Risk Prevention Plan (PPRN). The dataset, produced by the French Geological Survey (BRGM), represents areas exposed to a centennial marine submersion hazard, incorporating considerations for protective structures. It was last updated on March 25, 2019.
Use Cases
- Modeling coastal flood risk based on hazard intensity and probability levels described.
- Creating regulatory land-use maps for the PPRN based on the defined hazard zones.
- Assessing the impact of protective structures on hazard exposure as referenced in the description.
- Integrating multi-hazard risk analysis where zones are coded for multiple hazards.
Strengths
- Produced by the authoritative French Geological Survey (BRGM).
- Explicitly includes areas behind protective structures, acknowledging failure scenarios.
- Hazard levels are defined by both probability of occurrence and intensity of the phenomenon.
Limitations
- Last updated 2019-03-25 00:00:00; freshness should be verified.
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
