Application of MIKE11 Model in Water Quality Prediction of Hunhe River Basin

In view of the serious situation of water environmental pollution in Shenyang section of Hunhe River Basin in Liaoning Province,MIKE11 software is adopted to build hydrodynamic and water quality coupled model.And then the water quality observed data are used to parameters calibration and model test.Finally,the rationality of parameter is analyzed.Moreover,the effect of water quality changes and improvement is studied under different scenarios.The results show that the proposed model has good simulation effects,which provides reference for further research on water quality and also provides scientific basis for control pollutant emission in Shenyang City in future years.Three scenarios of natural growth,social regulation and social-economy-environment coordinated development are used to predict the water quality.Rationality of different development ways is also analyzed.It indicates that the third way is the most propitious one for the development of economic and environment.
