| Abstract: | Bed shear stress and friction coefficient have been studied. Based on the critical condition for the initiation of sediment movement by means of a lot of test data for a wave - current coexistent system, formulas of sediment initial movement for both laminar and turbulent have been set up, and wave height and water depth for initiation of sediment movement are given as well. |

| Keywords: | wave-current coexistent system boundary layer bed shear stress initiation of sediment movement wave height for initiation of sediment movement water depth for initiation of sediment movement |
