The UE "hydrological/hydraulic modeling and flood risks" proposes the study of the phenomenon of flood genesis, flood propagation and floods. The module aims to enable students to acquire skills in hydrological and hydraulic modeling of processes at the watershed and river scales:

1) The production function to separate rainfall into runoff and infiltration;

2) The transfer function on the slopes and via the river system, overflow and flooding ;

3) The construction of a project rainfall and synthetic hydrograph;

4) Applications of hydrological and hydraulic flood models.

The UE also includes a field day (acquisition of in situ data for hydrological/hydraulic modeling purposes, in situ analysis of flood risk).

The tutorials focus on practical applications on watersheds and rivers in France and abroad using spatialized hydrological flood models (e.g. ATHYS, MHYDAS) and hydraulic models (HEC-RAS, Diffusing Wave, Kinematic Wave, etc.): rainfall/discharge data analysis, use of hydrological/hydraulic models, parameterization/calibration/validation of models, analysis of the impact of development scenarios (dyke, dam, etc.).): analysis of rainfall/flow data, use of hydrological/hydraulic models, parameterization/calibration/validation of models, analysis of the impact of development scenarios (dike, dam, etc.).

This course covers the concepts of mass and heat transfer in aquifers as well as the characteristics of low to high energy geothermal energy.                                                                                                                                                                                                             

The vulnerability of the groundwater resource will be assessed and, if necessary, methods to protect the aquifer from pollution will be evaluated. Different techniques to clean up aquifers will also be discussed, in particular through the answers provided by numerical simulation tools.

The principles of geothermal energy will also be discussed through examples of specific devices based on the three types of geothermal energy (from shallow to very deep, from low temperature to very high temperature).
