Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...
Résumé Dans le cadre du projet de recherche sur la sédimentation de réservoirs à faible profondeur, en particulier les sédiments en suspension, les paramètres suivants ont été étudiés: l’influence de la géométrie du réservoir sur le transport des sédiments ...
The problem of transport of suspended sediment after the break of a dam on an inclined bed is considered. To that end we use the shallow-water approximation for arbitrary, constant slopes of the bottom, taking into consideration the effect of friction. The ...
The deposition behavior of fine sediment is an important phenomenon, which remains unclear to engineers concerned about reservoir sedimentation. In the present case bed level changes, suspended sediment concentrations, and flow velocities were measured in ...

The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
An overview is given on the experimental evidence suggesting that the magnitude of the initial fluctuations increases with cell size. For sufficiently thick cells, the magnitude is also shown to decrease over the entire time of the experiment, so that a st ...
We report on a series of soil erosion experiments performed on the 2-m x 6-m EPFL erosion flume. Total sediment concentrations and the concentrations of seven size fractions (1000 mm) were measured during 1 ...

Process-based erosion modelling has proven to be an efficient tool for description and prediction of soil erosion and sediment transport. The one-dimensional Hairsine-Rose (HR) erosion model, which describes the time variation of suspended sediment concent ...
The purpose of this study is to assess climat change impacts on hydrological behaviour at catchment scale and river regime with a special emphasis on sediment transport and mobile bed processes. ...
