RPRI Hazard Zones in the Baracci Watershed, Corsica

The Baracci watershed in Corsica contains areas exposed to one or more hazards, as represented on a hazard map used for risk analysis. The hazard map resulted from a flood risk study conducted by BCEOM in November 1998, leading to the first PPRI approved on 18/11/2004. Hazard levels are zoned based on the probability and intensity of dangerous phenomena, including areas behind protective structures.

Use Cases

• Modeling flood risk exposure based on hazard probability and intensity zoning.
• Informing land-use planning and development restrictions within the Baracci watershed.
• Assessing the effectiveness of existing protective structures against flood hazards.

Strengths

• Hazard zones are based on a specific 1998 study by BCEOM, providing a documented origin.
• Zoning incorporates both the probability of occurrence and the intensity of hazardous phenomena.
• Areas behind protective structures are included, accounting for potential failure.

Limitations

• The underlying hazard study dates from 1998; conditions may have changed since.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• The data format is WMS, which may require specific geospatial tools for analysis.
