瓜渚湖清水工程水流的流动传播特性，使水流流入流出瓜诸湖的时间位置不同，流速水位也不同，湖泊水动力特性呈现出复杂性。根据清水工程河网湖泊水动力二维数学模型的计算成果，分析了瓜渚湖及其周围河网之间水流的相互制约关系，及其呈现的低流速区域等复杂的水动力特性。根据水动力特性，提出了水系连通、河道拓宽和在瓜诸湖岸边设置观赏坝、观赏岛、设置水闸等导控设施，控导水流加快水体置换率等工程措施。

Because of its special flowing and transmission characteristics of Guazhu Lake , many factors about Guazhu Lake , such as the different time of inflow and runoff , the different flow velocity and water level , make the hydrodynamic character-istics of the lake water complex .According to the 2-D mathematical model calculating results of the river networks hydrody-namic force in Keqiao Clean-water Project, the mutual restriction relation of water flow between Guazhu Lake and the sur-rounding river networks is analyzed , as well as the other complex hydrodynamic characteristics , such as low velocity area . According to the hydrodynamic characteristics , some control measures as well as some engineering measures are put for-ward, including river system connection , channel widening , and the construction of ornamental dam , ornamental island and sluices, therefore, to speed up the water exchange rate .
