- Abstract:
-
The optimal location of water quality monitoring points in water supply network was explored, and defects of the demand coverage were analyzed. An optimized location method based on the coverage weight water quantity was proposed, which was to introduce the node water quality weight into the demand coverage location model. The weight demand coverage method considerd the spatial distribution of water quantity and quality of the nodes, and the influence of the surrounding pipeline properties on the node representativeness, which improved the representativeness of location of the monitoring points. The weight demand coverage method was applied to a water supply network in a district of Chongqing to optimize the location of water quality monitoring points, and the results were compared with the demand coverage method. At the same monitoring level, the monitoring points chosen by weight demand coverage method had better representativeness and practicability, which could provide reference for the location of water quality monitoring points of similar municipal water supply network.
