The finite element method(FEM) was used to simulate sediment hydrodynamics at the Beidaihe International Yacht Club,and a two-dimensional model was established.The sediment movement and deposition were analyzed under many tidal conditions in conjunction with the hydrological regime of the Daihe River.The peak value of the sediment deposition thickness appears in the main channel and around the estuary.The sediment deposition thickness is essentially constant and relatively small in the project area.The sediment deposition thickness in the main channel,in the yachting area,and around the hotel is greater than the other areas in the project.Regular excavation and dredging of the channel is the best measure for mitigating the sedimentation.
