Regulatory zoning reference profiles for flood risk management in the Vitry-le-François Marne-Blaise sector, published by the Bureau de Recherches Géologiques et Minières. The dataset contains reference water levels determined from hydraulic modeling of centennial flood hazards, expressed in NGF meters. Profiles are positioned with an altimeter deviation of about 20 cm and are used to define construction regulations.
Use Cases
- Determine regulatory construction heights for habitable floors based on reference ratings increased by 5 cm.
- Assess flood vulnerability for electrical installations based on reference ratings increased by 30 cm.
- Visualize centennial flood hazard water levels across the Marne-Blaise sector.
- Locate reference profiles upstream of a site for regulatory zoning compliance.
Strengths
- Reference profiles are linked to the General Level of France (NGF), providing a standardized vertical datum.
- The dataset is based on hydraulic modeling that determined centennial flood hazards.
- Regulatory ratings are defined with specific increments (5 cm and 30 cm) for different construction elements.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
