The Plan for the Prevention of Natural Risks of Field Movements (PPRMT) for the northwest sector of Saint-Viance, Corrèze, was approved on 3 November 2009. It was created by the Bureau de Recherches Géologiques et Minières after analyzing soil instability based on geological formations, hydrogeology, and morphology. The regulatory mapping defines three hazard zones dictating construction permissions based on hazard intensity and existing stakes.
Use Cases
- Assess land suitability for construction based on defined hazard zones.
- Model risk exposure for existing infrastructure based on the hazard classification.
- Inform regional land-use policy and development regulations.
- Visualize spatial distribution of ground movement hazards for public awareness.
Strengths
- Regulatory mapping approved by a specific date (3 November 2009).
- Hazard analysis based on three concrete factors: geological formations, hydrogeology, and morphology.
- Defines three specific regulatory zones with clear construction implications.
