- Abstract:
-
In order to solve the problem of inaccurate node flow distribution of water supply network hydraulic model, a new node flow distribution method based on a water supply network hydraulic modeling project in J city was proposed. This method first divided the water supply area according to the business sales data, and adopted GIS technology to find the water consumption node by using the “water meter up-tracking” method. Node flow in the allocation method was the sum of the business scales node flow and the non-revenue water node flow. Business scales node flow was determined by business scales data. The traditional linear flow method and the population density method were used to distribute the difference between the production and sales of the nodes in each water supply area. The node flow rate assigned by the two methods could meet the requirements of flow monitoring point error and pressure measuring point relative error. After comparison, it was found that the model accuracy was higher when the population density method was applied for the flow distribution calculation.
