Study On Siltation Of Lianyungang Port Based On 3D Numerical Simulation Technique

The siltation in Lianyungang port is studied by the three-dimensional numerical simulation technique. The results show that: 1. The sediment in the port mainly comes from the silt of the nearshore and shoals. Under the combined action of wind, wave and currents, the sediment is suspended and transported, and the suspended sediment gradually siltes along the channel, and the position of maximum sediment thickness point at the entrance. 2. Through the mathematical model calculation, the monthly silting strength of Qitai, Mianling and Xugou port is determined. In addition, the silt will be aggravated by the wind or typhoon weather conditions, and the sediment thickness of each port can be revised according to the results of the study.
