PPRI 2013 Dordogne Basin: Flood Hazard Isocote Lines for 15 Communes in Corrèze

Lines and values of isocotes for the reference flood defined in the 2013 PPRI plan for the Dordogne basin and its tributaries. The dataset covers 15 municipalities in the Corrèze department of France, with hazard derived from modeling historical and centennial floods. It was published by the Bureau de Recherches Géologiques et Minières and last updated on January 14, 2022.

Use Cases

• Mapping flood hazard zones based on modeled isocote lines mentioned in the description.
• Informing land-use planning and construction regulations based on the defined red, dark blue, and blue zone classifications.
• Analyzing flood risk for specific rivers (Dordogne, Maronne, Souvigne, etc.) using the referenced historical and centennial flood events.

Strengths

• Covers 15 specific municipalities in the Corrèze department, providing localized hazard data.
• Hazard modeling is based on defined reference floods, including the historical October 1960 event for some rivers and calculated centennial floods for others.
• Explicitly linked to an approved regulatory plan (PPRI) from October 30, 2013, providing a legal and temporal context.

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 00:00:00; freshness should be verified.
