Abstract

The estuary of Qiantang River,a very important water-supply source of Hangzhou City,has a severe hypoxia. In this paper,a coupling flow and water quality model of Qiantang Estuary based on mike 21 is established,which can simulate hydrodynamic and DO responding to BOD,NH3-N and NO3-N. With the help of the model,the water quality variation of Qiantang Estuary responding to sewage quantity of Fuyang City and runoff volume is quantitatively studied,and then suggestions on how to improve hypoxia are put forward.
