【Abstract】 A varied boundary tidal current numerical model of Jiaozhou Bay is established using the split steps finite element method. The current distributing pattern of this area is modeled by calculation. Predictions are made according to several sea filling plans, and the impact of the hydrodynamic factors such as tidal current, water level, etc. are obtained. It shows that the bigger the area filled and the more the impact and that the effect of blocking currents is larger than that of downstreams, and that the effect in the area of high current is stronger than that in the area of low current.更多还原
