- Abstract:
- In order to simulate changes in the water quality of the Miyun Reservoir due to continuous descent of surface water level, a 3-D ecological hydrodynamic model was developed through coupling the water quality analysis simulation program(WASP)with the environmental fluid dynamics code(EFDC).The model was then calibrated and verified.Four scenarios(S1, S21, S22 and S23)were simulated using the model.Results show that the water quality of the Miyun Reservoir under conditions of low surface water level is apparently affected by different amounts of inflow and different total phosphorus(TP)loadings.The chlorophyll-a concentration might exceed 10 μg/L in many areas of the Miyun Reservoir(This limitative value is seen as a critical value of eutrophication)when large loadings of TP enter due to the amount of inflow increasing.Results of scenario S23 indicate that control of TP loadings can decrease chlorophyll-a concentration effectively, and the water quality of the Miyun Reservoir will improve or retain its status quo.
