The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...

An implicit depth-averaged 2-D finite volume model has been developed to simulate sediment transport and bed morphological changes under actions of currents and waves near coastal inlets. The model computes the depthaveraged 2-D shallow water flow and non-equilibrium transport of total-load sediment, accounting for the effects of wave radiation stresses and turbulent diffusion induced by curren...

Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
