Mesures et modélisation des flux de sable dans les cours d'eau : application à une chasse de barrages

Abstract : Measurement of sand flow in rivers is an issue for scientists and managers of watercourses, particularly in relation to the management of dams. Indeed, this measurement is very difficult because sands are transported over the entire water column but non-homogeneously with very high concentrations near the bottom. Knowledge of sand flow is still very limited though these are non-negligible and can have major impacts on river morphodynamics. A flush Rhone dams held in May 2016. This event was an opportunity to display various measuring instruments for sand flow under controlled conditions. The work done during this graduation report allow for a state of bibliographic knowledge on the measurement of sand flow. It has established an experimental protocol adapted to highlight the distribution of the transported sand in rivers and improved different approaches for the sand flow modeling.
