| Abstract | Yongding River has been one of the major sources for supplying water for the capital of China, Beijing. However, as a result of the development in economy and industrialization, more and more pollutants are discharged into the river to get rid of the waste, thereby utilizing the selfpurification capacity of the river. The China Water Quality standard II has presently been adopted on the part of the river where withdrawal of water for Beijing takes place. To study the water quality condition of the river, especially the BOD/DO distribution along the river, MIKEl 1, an advanced and sophisticated numerical computer tool, developed by the Danish Hydraulic Institute, has been applied in this study. The modelling is based on the measured data from 1991. The Hydrodynamic module (HD) and Water Quality module (WQ) of MIKEl 1 were set up and validated for this year. Sensitivity analyses have been used in testing the influence of parameters such as photosynthesis, reoxygenation and deoxygenation coefficients. By utilizing this modelling tool, various future scenarios have been studied and the necessary extent of waste water treatment has been recommended to meet the standards adopted for this river part. The evaluation of the numerical modelling tool in water quality management has been conducted based on the case study of Yongding River. It is concluded that numerical modelling tool is fast and efficient for managing the river water quality. |
