摘要

The knowledge of advection and dispersion processes in rivers is a key point in the prediction of suspended sediment transport. Depending on flow characteristics, advection or dispersion transport could be predominant. Moreover a large number of formulae for dispersion coefficient estimation could be found in the literature. In order to predict dam flushing downstream effects, we are interested in suspended sediment transport in the Arc River. We decided to investigate the dispersion processes in details in order to better parameterize the future sediment model. The Arc River is a torrential river of the French Alps with a slope about 1% and important hydroelectric development that could produce low discharges. Dams and reservoirs of the upper Arc River are managed by EDF (Electricity of France).
