Abstract:A calculation pattern, which combines horizontal upwind finite element method with vertical implicit difference. istaken as our calculation procedure to set up 3-dimensional mathematical model of tidal motion and sediment transport in tidal current. By comparing with the relative theoretical formula, the results are satisfactory. The model mentioned above has been appliedto the water area of the I.ianzhou Bay, Zhuang Autonomous Region of Guangxi. On the basis of analysis and comparison with thefield data, it is shown clearly that the model calculation results are reasonable.
Keywords:Tidal current  sediment transport in tidal current  upwind finite element  3-dimensional numerical simulation
