Study On Water Resources In Xianlin Reservoir Of Hangzhou

The 80% drinking water source of Hangzhou city was taken from the QianTang River, which had a significant impact on the water quality of the River’s estuary. For city construction Xianlin reservoir water reserve, has important significance to guarantee the safety of drinking water in Hangzhou city. Paper for the planned Xianlin reservoir water quantity, and the capability of water supply, water quality, anti salt and flood control capacity and water source protection and other issues to carry out research, provide a reference basis for reservoir engineering construction scheme.Through to watershed and water diversion water analysis, calculate the Xianlin reservoir different guarantee rate under the conditions of storage, water supply, and according to Xianlin reservoir water supply planning, to determine the condition of the reservoir in different function of total water supply reservoir and analyze storage, water supply scheme is reasonable. In addition, through the investigation of pollution sources, the existing water environment was evaluated, and the influence of the return water of the reservoir to the water environment was analyzed.This paper attempts to simulate and predict the water quality in Xianlin reservoir. Based on the investigation and evaluation of the state of the water source, the key factors affecting the environmental quality in the area are understood. According to Xianlin town in recent years, the development of the status quo and reservoir watershed pollutant emissions monitoring, water environment capacity calculation of reservoir, on the tributaries of the water environmental capacity distribution, determine the tributaries of the export of the storage load, eventually of reservoir water quality in future was predicted.According to the reservoir’s water solution,make up planning schemes for protecting the environment of the water source, make the benefit assessments of project implementing and establish security systems of programme implementation from aspects including water pollution control and partition, ecological control projects, ecological protection projects, ecological restorations and construction projects of surveillance systems at the water source respectively.
