%X In this paper, three-dimensional model ECOMSED was used to simulate the evolution of the seabed terrain under the condition of tide and wave (imposed by the wind), and to analyze the variation of scouring and depositing after the completion of Zhangjiabu new port construction at Jinghai bay at Weihai. The shear stress that imposed by the joint action of wave and current to the seabed, is equal with the critical stress of incipient motion of sediment, so that the variation of scouring and depositing can be analyzed. It was shown that the seabed was eroded badly near the open section of the approach embankment and the terminal of the breakwaters, where the maximum values of scouring depth for 50 and 25 years return period are up to 3.5 m and 2.9 m, respectively. This conclusion may provide reference data to protect against scouring.
