Abstract: The model for prediction of time and space variations of suspended sand concentration over plane bed under waves with group structure is described. The convective sediment flux is described by formula based on the field and laboratory data. The sediment entrainment from the bottom is represented by a pick-up function that takes into account the phase shift between the suspended sand concentration and the flow velocity. The examples of measured and predicted temporal variations of the suspended sand concentration are presented.
