摘要

Due to frequent pollution incidents in the middle of Huai River, effective operation scheme is needed for practical application. Thus, this study selects the Yingshang sluice of Shaying River (in the Huai River watershed) as a case study to investigate optimisation model of pollution-control regulation to obtain an optimum operate scheme. We coupled the hydrodynamic-water quality (HWQ) model and the Multi objective optimisation model to a new developed model. The model is resolved by multi-objective genetic algorithm and validated by measured field hydrology and water quality data. The result shows that Yingshang sluice regulation obtained from optimum model can effectively reduce the negative influences of pollution incidents caused by Shaying River sewage, with respect to reservoir profiting and pollution-control. This model proposed in this paper can give some insight to further study about decision making of operation rules in heavily polluted rivers.
