Due to the absence of the ground resource, the construction land of the general aerial industry base is planned to get from reclamation in the east of Meishan to construct infrastructures in order to satisfy the functions planning of Meishan. We use the MIKE 21 HD model to simulate the influence on current due to the planned five different reclamation scenarios in the east of Meishan after plugging the Meishan waterway, and make a comparison according to the modeling results. The modeling results reveal that the influence of the planned reclamation project to the larger area tide field is little. Generally speaking, the influence of the first scenario is the least as its reclamation area is the least among the five scenarios. While the fifth scenario has the least influence on the south Chuanshan operation area, as the waterway between Pusheshan mountain and Meishan is not plugged.
