| Summary: | In order to optimize the scheduling of sluice pump groups in river network of delta,guarantee the river and lake system interconnection and improve the water environment of rivernetwork, based on the 1D-3D water quantity and quality coupling model of river network under theinfluence of sluice pump groups, this paper takes Zhongshun embankment as the research object andstudies and compares three scheduling modes as follows: fully-open sluices, independent diversionand drainage and unidirectional flow scheduling. The results show that the water environmentimprovement effect of unidirectional flow scheduling mode is better than that of the other twoscheduling modes. Based on the unidirectional flow scheduling mode, the research on sluice pumpgroups scheduling which takes saltwater resistance of rivers and improvement of regional waterenvironment into account is carried out, and under the condition of satisfying the ecological flowduring the period of saltwater resistance of rivers, the water environment improvement schedulingscheme of Zhongshun embankment is obtained. The research methods and results can be as a referencefor formulating the joint scheduling scheme of sluice pump groups and planning & constructing theregional water system. |
