wave%threshold of sediment movement%boundary layer
A review of former studies on the onset of sediment movement under wave action reveals that the Shields criterion obtained in unidirectional steady flow can also be applicable to oscillatory unsteady flow when the boundary layer is the same. In this paper, through comparison of different boundary layers in wave and steady flow conditions, a new criterion is presented which can be used to predict the threshold ofsediment movement under wave action. The criterion curve shows good agreement with the experimental data.
