Description :
Experiments were conducted in the laboratory to evaluate the influence of sediment concentration, sediment grain-size distribution, bed slope and flow discharge on sediment deposition rates and patterns associated with a reduction in bed slope. More specifically, the study investigates to what extent sediment deposition (both total mass and sediment quality) can be predicted using the simple theory for flows with a shear stress below the threshold value, and which modelling approach can best be used once the threshold value is exceeded.
