Emergency Water Supply Dispatching Model for Saving and Storing Fresh Water in River Network Areas Influenced by Saltwater Intrusion
摘要
Abstract
There is difficulty in grasping the opportunity of saving fresh water and low efficiency of saving and storing fresh water in emergency dispatching of saving and storing fresh water in river network areas influenced by saltwater intrusion.To this end,according to water system conditions,hydrodynamic characteristics,and saltwater intrusion rules in river network areas influenced by saltwater intrusion,this paper builds an emergency dispatching model for saving and storing fresh water based on the raw water system in these areas.The emergency dispatching includes four parts:saving fresh water by the sluice,storing fresh water by branches,regulating saltwater by reservoirs,and supplying fresh water by pump stations.Additionally,an empirical analysis is carried out in the Levee of Zhongshan and Zhuhai in the Pearl River Delta.The research shows that the water supply security in dry seasons can be effectively guaranteed if the volume of branches within the Levee of Zhongshan and Zhuhai is made full use of,the joint dispatching of Majiao Sluice,Lianshiwan Sluice,Denglongshan Sluice,and Dayongkou Sluice is conducted,and fresh water is saved from Modaomen Waterway intermittently to store fresh water in the branches.Besides,when the salinity of Modaomen Waterway exceeds the standard level,Tielushan Reservoir is employed to drain the fresh water and regulate the salinity,which can further improve the water supply security and alleviate the influence of saltwater intrusion.关键词
