Mathematical Model Of Tide And Sediment Transport Of Nanpai He Fishery Port

In the coast engineering,the velocity field and the sediment transport play important role in the construction and maintenances. The numerical simulation of the current and the movement of the sediment is necessary both in supplying the information and in analysing the project. In present thesis, a 2D numerical simulation is applied to study the plan arrangement of Nanpai He fishery port, and simulate the current and sediment transport of 4 cases, and at last the better one is proposed.In order to get a high precision solution and decrease the calculating time, the nesting method is applied in the simulation- that the first model considering the large area is established to supply the boundry condition on the open boundry of the second model, and the second model considers the area which we want to study. The result of the flow and the sediment transport simulation are verified by the data on site. It shows that the numerical model can describe the principle of the sediment transport. The bed erosion and deposition of different projects are forecasted successfully.
