摘要
从区域外引入清水,不但可以置换污水而且可以增强河网水动力,降低水体富营养化的发生.根据建立的绍兴柯桥主城区河网湖泊水二维水动力数学模型,计算了河网水力要素,分析了局部河段和整体河网的水力特性,确定了河网中最需要进行河道拓宽、通过水闸和泵站等工程增加水流流速、控制水体流动的河段、需要进行水系连通的河段,为实施增强河网水动力应该采取的措施提供了依据.
The fresh water introduced from outside the region can not only replace the sewage to enhance river water power,but also reduce the eutrophication of water body. According to the established two-dimensional hydrodynamic mathematical model of water area in downtown Keqiao,Shaoxing,the river hydraulic elements are calculated,the hydraulic characteristics of the local section and the whole river network are analyzed,determining the critical sections in the waterways which need broadening to increase flow velocity by the gate and pumping station project. The sections asking for water flow control and river system connection are also confirmed,providing the basis for hydrodynamic force improvement of the river network.
