Forecasting Effect of Flow Reduce of Changjiang River into Sea on Chenhang Water
Gu Yuliang Jin Dihui
That water supply in Shanghai city wants to reach European standard must be on the premise of good quality and stable raw water. Development and use of great quantities of good quality Changjiang water are the best choice to change unreasonable the structure of water source and unstable water quality. Though the Chenhang Water Source supplies water with Changjiang large aquifer, the reservoir is of smaller capacity. so a series of problems have currently been emerged. Some uncertain reasons such as change of natrue and important retaining and diversion works in Changjiang River basin etc lead to the reduce of Changjiang flow into sea and salt water erosion to water intake so as to cause more unfavorable effect to Chenhang water source. In order to let civilians drink better Changjiang water, some measures must be taken, for example, to enlarge the capacity of existed Chenhang Reservior and to adjust the position of water intake etc, thus the alteration for lack of good quality water will be made in Shanghai.
