Une contribution pratique à l'estimation du transport des sédiments dans un écoulement fluvial

Several computational methods of sediment discharge in open channel flows are reported in the existing literature. However, sediment transport is a complex procedure that implies several parameters which in some cases are difficult to estimate. Even if direct confrontations of methods used are published, it is difficult to draw significant conclusions that would help determine a model or the models likely to produce the best results for a specific case. To facilitate that choice, the authors have attempted to establish a classification of the various methods commonly used by determining their relative performance, and to improve the performance by proposing a new model which distinguishes the type of sediment transport and the nature of the bed. Key words: sediment discharge, sediment transport, open channel flow, model, performance.[Journal translation]
