| Abstract: | Taking the water supply network in Tianjin as an example, three flow distribution schemes were provided for the hydraulic model of water supply network with partition measurement by analyzing the characteristics of measured water quantity, the requirements of the hydraulic model establishment and water quantity data from community water meters, indoor water meters and on line flow meters. Furthermore, these schemes were multi-angle evaluated from eight aspects, such as data integrity, accuracy of node demand distribution, difficulty of implementation, basis of correcting for node demand distribution, function of leakage inspection, dynamic simulation of model, difficulty of maintenance and application of model, platform construction of model. It could provide reference for the implementation of project. |
