Effect Demonstration on Flood and Tide Control for the Hengqin Sea Reclamation Planning Scheme in Zhuhai

By using the 1D and 2D mathematical model,choosing the hydrology group of flood“98.6”,the medium flood“99.7”,the dry flood“2001.2”,the“2005.6”(flood spring tide),the“2003.7”(medium spring tide) and the“9317”storm tide,it simulates the effect of the recent and long－term sea reclamation planning scheme in the south of Hengqin district on the nearby waterways and the surrounding water.The conclusion is given that the long－term planning scheme has obvious adverse effect on nearby waterways.
