Numerical simulation and analysis on tidal current and sediment silting process in Yellow River estuary

The Finite Element Method(FEM) is applied to numerically simulate the tidal flow in the vicinity of the river mouth of Yellow River.The calculated result shows that the areas with high current velocity exist at the outside of the river mouth and at the junction of Bohai Bay and Laizhou Bay.According to the contour lines of sediment deposition, the variation process of deposition thickness along the flow direction as well as the contour lines of seabed, the deformation process of the seabed is analyzed.The calculated result is in good agreement with the observation data as well as the interpretation graphics of satellite remote-sensing data.
