Title of the thesis : Experimental study of sediment transport under unsteady flow conditions: application to the remobilization of sediment recharges
This project would be under the supervision of : Damien Calluaud, D2-FTC department of PPRIME Institute at Universite de Poitiers.
Co-supervisor(s) : Guillaume Gomit /
Starting date: 09/2022
This project focuses on the experimental study of sediment transport under unsteady flow conditions. In particular, the project aims to model in the lab flow variations (hydrograph) downstream of hydroelectric dams based on field data. The project will focus on the mobilization of sediments, resulting from sediment recharging operations, under typical flood flow variations. These experiments will allow to link hydrodynamic quantities to the transport of sediments over time during the flood event. A parametric analysis taking into account the hydraulic properties (flow slope, minimum and maximum value, duration) will be conducted for a range of sediments representative of a typical sediment recharge. Scale effects, inherent to laboratory modeling, will be evaluated to validate the laboratory models. This work will improve existing transport models under variable flow conditions.
