河湖水系连通与优化调度补水的效果

Effect of Interconnection of Rivers and Lakes System and Optimization of Water Control for Operation and Supplement

文中介绍,为维护三条河涌生态基流及改善水质,基于补水调度试验水文水质同步监测,利用MIKE11建立相应河网水动力模型,通过对补水流量、补水时间、景观水位、开泵时间、起调水位等控制指标的优化研究,提出了河涌补水的优化调度方案。方案很好地指导了三涌联合补水工程的实际调度,在改善河涌水环境的同时,节省了运行成本,有很好的实用性。

In this paper, in order to maintain “Three Rivers” ecological basic flow and improvement of water quality, based on monitoring for hydrology and water quality of water supplement test, river networks hydrodynamic model was established using the MIKE11. Optimization schemes of river operation for water supplement was presented through optimization study on the control indexes such as supply water quantity, supply time-period, landscape water level , pumping station boot time and priming water level of regulation. Operation schemes were used in the actual operation of “Three Rivers” joint water supplement project, which had a very good effect on improving water quality and saving cost.
