Abstract
Modeling of bed load sediment transport for fluvial flow The mathematical modeling choices of bed load transport in rivers must be confirmed by precise data. Collection of field data is long and difficult. Besides, the parameters of natural flows, such as discharge cannot be controlled. For these reasons a 50 m long flume was set up. It makes possible with the help of precise data, no study independantly some of the important physical phenomena involved in bed load transport, such as hydraulic resistance, influence of non uniformity of grain-size, spatial lag effects. This study has been carried out as part of the convention EDF-Ministeres of July 23, 1965.
