Water environment prediction and evaluation on reservoir dredging and source conservation project—case study of duihekou reservoir

Abstract

In order to study the effect of dredging project on water supply safety of the reservoir, a case study of Duihekou reservoir is taken in this paper. On the basis of the characteristics of water environment, sediment and the surrounding pollution, analyze of the related activities of the project, predict the influence of the water head site dredging project on water environment, especially water intake and scenic area. The results show that chain bucket dredger only has a certain impact on the dredging area and nearby, the overall impact on the water quality of the reservoir is small, and the dredging project does not affect the water intake basically. Disturbance effect of wetland type dredging dredger is similar to chain bucket dredger.
