Hazard zones representing the centennial flood risk for the Orconte sector in Frignicourt, based on hydraulic modelling from 2018. The data includes areas considered hydraulically transparent, where protective structures are present but risk of failure is accounted for. The dataset was produced by the hydratec design office for the BUREAU DE RECHERCHES GÉOLOGIQUES ET MINIÈRES.
Use Cases
- Flood risk zoning for land-use planning based on the graduated hazard levels.
- Infrastructure vulnerability assessment based on the concept of hydraulic transparency for protected areas.
- Validating or comparing flood models using the 2018 hydraulic modelling results mentioned in the description.
Strengths
- Based on 2018 hydraulic modelling by a named design office (hydratec).
- Includes the concept of hydraulic transparency for areas with protective structures.
- Explicitly defines 'zero, insignificant or white zones' where hazard is nil.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2022-01-27 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
