Watercourse Overflow Flood Hazard Studies
Description
The aim is to improve knowledge of flood zones and hazard: delimit flood zones for frequent and intermediate floods with associated water heights/speeds (for floods of first overflows, Q10, Q30, Q50; delimit flood zones for reference (centennial or historical) and extreme (millennial) floods. Identify the strong and moderate hazard in these zones (criterion of discrimination of water height: 0.50m, speed: 0.5m/s)The hazard maps are implemented from a field diagnosis, a hydrological analysis of the study area, mathematical hydraulic modelling type rain/flow correlated to topographic levers (type Lidar) provided or carried out as part of the study.
