Mathematical Model of Deepwater Harbor in Changing Island

Dalian Changxing Island is located near the east coast of Liaodong Bay, Bohai Sea, China. Changxing Island has high quality resources of deep-water coastline. In order to develop deep-water harbor for 300000 dwt ships, it is necessary to set up the hydrodynamic and sediment mathematical model. In this paper, the Characteristics of hydrodynamic and sediment is analyzed according to observation data firstly, secondly, the tidal and sediment model is set up based on TK-2D software with triangular grid. Thirdly, we analysis the tidal current characteristics and bed level evolution of whole port after the scheme.
