The Study On Impact On The Reservoir Envioronmental Capacity Of The Reservoir Outflow

With the rapid development of water conservancy, Reservoir environment issues is concerned increasingly. This paper Shanghai Chenhang Reservoir as the research object, use the CFD software calculate the flow by changing the width of the outlet and then import the flow data to the calculation software development environment WASP7 which is designed by United States Environmental Protection Agency and calculate the pollutant concentrations in different outflow discharged from the reservoir,then calculate the water environmental capacity.According to the reservoir flow and concentration distribution of Reservoir flow ,at last analyse the relationship among the outflow and the width discharged volume of reservoir water environment and the water environmental capacity by drawing the relevant pictures and charts, that can be carried out after the reservoir water environment-related research workers to provide reliable basis.This paper is divided into the following parts:Part I: Describe the background of This study and point out the main contents of the study ;Part II: Establish the relevant mathematical model accord to the actual situation ;Part III: Draw the mesh of the reservoir and use the Fluent software to calculate the flow field;Part IV: Calculate the distribution of pollutant concentrations of the reservoir;Part V: Calculate The environmental capacity of the reservoir;Part VI: Analyse the relations of the three,and aggregate the study.
