疏浚工程对湖泊水动力学特征的影响分析

Effect of dredging project on the hydrodynamic of lake

本文以东太湖为研究对象,建立了二维湖泊水动力,根据东太湖疏浚工程实施前后地形的变化进行水动力模拟。水动力模拟结果表明,疏浚工程实施对疏浚湖区水动力学参数的影响较为显著,而对太湖整体水流结构的影响微弱。

This thesis uses East Taihu Lake as the research object,a 2D hydrodynamic and water quality model was built.the flow characteristics of dredging lake is simulated and analyzed.The changes of hydrodynamic before and after the implementation of dredging project.Hydrodynamic simulation results show:The implementation of dredging project have a significant impact on hydrodynamic parameters of the dredging lake region,and a weak impact on the the Taihu lake overall flow structure.
