  • Leakage in water distribution network (WDN) is a common and worldwide problem.How to effectively reduce the leakage rate and locate the leakage is an important problem which perplexing China's water supply industry.The leakage location methods based on hydraulic model and online monitoring data can quickly identify the leakage events in WDN and achieve preliminary location.However,such methods depend heavily on model accuracy,and also lack sufficient actual leakage case data in WDN for testing.To address this,the laboratory pipe network model was built in this study,and the SCADA system was arranged to monitor the pressure and flow data,so as to realize the simulation of WDN,which can be used to generate the simulation data of various leakage in WDN and test the effect of leakage location method.Moreover,by changing the leakage location and flow,model accuracy,as well as optimal layout of monitoring points,this study identified the influencing factors of the leakage location.
