Abstract:
Long-distance water transfer projects have large carrying capacity, numerous control gate groups and offtake groups, and put high requirements on controlling . In the event of a water pollution incident, it is essential to ensure the stability of the water transfer process and to handle the emergency efficiently. In this paper we studied the hydraulic control schemes of level ó water pollution in the main channel of the Middle Route of the South-to-North Water Transfer Project. We put forward the emergency handling strategy of level ó water pollution, and determined a division method of hydraulic control units based on the hydraulic characteristics of the offtakes. Taking Jing-shi section as an example, we proposed three emergency contro lschemes, and established a coupled model of one-dimensional hydraulics and water quality to simulate the flow of water and the transport of typical pollutants under different control schemes. The research showed that the three emergency control schemes could all achieve the emergency control objectives by using the channel's own storage capacity or exercising the control function of the offtakes without abandoning the water or significantly influencing the operation of the upper and lower reaches.
