基于闸泵联控的感潮河网区水动力水质调控

通过Mike11建立基于闸泵联控的水动力水质调控模型,设定水动力水质调控多目标函数并选取灰色多目标优选算法进行效果评选。以珠江三角洲中顺大围为例,用调控模型分析其在现状调度情况下的水动力水质特征,发现研究区的水动力及水质与相邻外江的水动力呈正相关,与相邻外江的距离呈负相关,河网水动力及水质整体较差。鉴于此,结合调度原则制定的5个闸泵联控方案均能较好地改善研究区的水动力水质条件,经过灰色多目标优选算法筛选出最优方案。提出基于闸泵联控的感潮河网区水动力水质调控模型能较好地展示不同闸泵联控方案下水动力水质改善的综合效果,可供类似感潮河网区水动力水质调控借鉴。

Regulation of Hydrodynamics and Water Quality in Tidal River Network Based on Gate-pump Joint Operation

A hydrodynamics and water quality regulation model based on gate-pump joint operation was built with Mike11. Multi-objective function was designed and the effect of regulation schemes was evaluated by grey multi-objective optimization algorithm. The hydrodynamics and water quality are positively correlated with the hydrodynamics of adjacent external river,but negatively related with the distance from adjacent external river. The model is applied tothe Zhongshun large polder in Pearl River Delta and demonstrated that the water power and quality is bad in general. In view of this, five schemes of gate-pump joint operation were put forward to improve the hydrodynamics and water quality in the study area, and an optimum scheme was selected using grey multi-objective optimization algorithm. The present model is verified to well demonstrate the comprehensive effect of hydrodynamic and water quality improvement under different regulation schemes of gate-pump joint operation, and offers reference for similar tidal river networks.
