Five hazard zones classify low coastal areas in South Corsica based on projected water heights from marine submersion. The atlas, produced by the Bureau de Recherches Géologiques et Minières (BRGM), was revised in 2020 and distributed to local mayors in January 2022. It provides static offshore sea levels for current and projected 2100 centennial events, incorporating climate change impacts.
Use Cases
- Prioritize land-use planning decisions based on the five defined hazard zones (red, blue, green, purple hatched, red hatched)
- Model coastal flood risk for infrastructure projects using the provided static offshore sea levels for current and 2100 centennial events
- Inform the development of Coastal Risk Prevention Plans (PPRL) with the hazard knowledge base from this atlas
Strengths
- Defines five distinct hazard zones with specific water height thresholds (e.g., >50 cm, <50 cm) for baseline and 2100 scenarios
- Includes specific precautionary band distances (25 m and 50 m) for areas behind wave impact zones
- Provides sea level projections for both a current centennial event and a 2100 centennial event, factoring in climate change
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
