Application of MIKE 21 Model in Water Quality Simulation of Ganjiang River Entrance and Adjacent Poyang Lake
In order to analyze the impact of the planned Nanchang hydro-junction on the water quali-ty of Poyang Lake area under the normal dispatching and operation conditions,in view of current water quality situation,the main pollutants COD,ammonia nitrogen,TN and TP were taken as indi-cators,and the MIKE21 model was applied to establish a simulation of the water quality evolution of the Ganjiang River estuary area and the Poyang Lake water area.The simulation results show that the impact of the planned Nanchang hydro-junction on the water quality of Poyang Lake is mainly concentrated at the lake entrance and nearby areas,the overall impact on Poyang Lake is small.Af-ter the normal operation of the planned hydro-junction,the water quality concentration of the Poy-ang Lake assessment section of Nanjishan and Wuhu sub stations near the Ganjiang River has de-creased;The concentration of water quality in the assessment section of Poyang Lake near Jinxizui and Nanhu Village has increased,which does not change the water quality category of Poyang Lake and has little impact on Poyang Lake.
