Presentation
This research theme focuses on the physical analysis and modeling of surface runoff in order to meet the expectations in the field of environment and sustainable development. The theoretical and numerical modeling of the physics of free surface flows covers both natural and experimental cases, and several measurement techniques, some of them being developed in the laboratory. With models and experimental/satellite data of first hand, our research aims to further enrich these models with the integration of sensitivity analysis and inverse problems. On an applicative perspective, this theme is related to the study of flooding, sediment transport in rivers, and conversion of hydropower.
Flooding pilot
The flood pilot is an experimental device 5x5 m² built in 2012 [8-Arau12] and representing an urban suburb on a scale of 1/200. This platform, which is unique in the world in terms of size and complexity, can be used to simulate flooding in urban areas in order to study the water flows in the streets or crossroads (steady state) or a wave displacement between buildings. It is equipped with devices for automated acquisition of water height and velocity field distributions at any point of flow. The experimental data allows to understand the physical phenomena associated with the flood propagation in the city, the water-flow relationship in a pipe [2-IDBF14, 2-IDFV14], the processes of trapping suspended matter [2 -SDVF14, 3-SDVF13], and the phenomena of deposition / suspension [8-Schm13]. Our numerical models (Navier-Stokes and Saint-Venant equations) benefit from the presence of the pilot: the comparison between experimental results and numerical simulation allows to validate the mathematical models [1-AFLF14, 2-SDVF13, 2-AFABxx] and to propose adapted numerical schemes [2-AFGM12].
