感潮地区引清调水方案研究

实施引清调水工程是改善感潮地区城市运河水环境的一项重要辅助措施。利用涨落潮差调水时．确定合理的闸门调度和引排水方案．对于减轻闸下冲刷、确保闸体安全和发挥调水效益有着极其重要的意义。为此，提出了一种控制闸下冲刷的闸门调度方案，建立了引清调水水流水质模型。以浦东张家浜运河为例．计算其闸门调度方案．并通过模拟不同方案下运河水质变化，分析得出了优选的调水方案。

Research on Scheme of Clean Water Diversion in Tidal Area

Clean water diversion is an important and helpful measure to improve the water quality in city canal of tidal area. As the water level in tidal area is changing fast, it is very important to choose a scientific gate operation scheme and a diversion and drainage scheme in the course of clean water diversion, and this will help to control scouring downstream the gate and to get better effect on the water quality improvement. So, in this paper a method is put up to control downstream scouring, and a mathematic model is developed to simulate water quality change in the course of clean water diversion. Taking the Pudong Zhangjiabang Canal for example, a gate operation scheme is worked out and water quality character of different schemes is simulated. Through the comparison, a proper scheme is selected.
