PPRI 2013 Dordogne Basin: Flood Hazard Contours for 15 Municipalities

Approved on 30/10/2013, this dataset contains the lines and values of flood elevation contours (isocotes) for the reference flood event in the Dordogne basin and its tributaries. It covers 15 municipalities in Corrèze, France, including Argentat-sur-Dordogne and Beaulieu-sur-Dordogne, and was produced by the Bureau de Recherches Géologiques et Minières. The data was last updated on 2022-01-14.

Use Cases

• Delineate flood-prone construction zones based on the defined red, dark blue, and blue hazard classifications.
• Model floodwater elevation and extent for the reference flood event based on the isocote lines and values.
• Assess regulatory compliance for new constructions in the 15 covered municipalities based on the PPRI rules.
• Analyze flood hazard for specific rivers like the Maronne, Souvigne, and Sagne based on the modeled reference events.

Strengths

• Covers 15 specific municipalities in Corrèze, France.
• Based on modeled flood hazards for multiple rivers, including the Dordogne and Maronne.
• Defines specific regulatory zones (red, dark blue, blue) for construction.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last updated 2022-01-14; freshness should be verified.
