In this study, algorithm for the selecting the optimum monitoring location and leakage detection algorithm based on back tracing
calculation method were developed and verified by the experiments in pilot plant of water distribution system. First of all, optimum
monitoring locations were selected and pressure changes were measured due to artificial leakage by pressure gauges in pilot plant.
Simulations of leakage detection was performed for the verification of back tracing calculation method as a leakage detection method.
From the results, it was found that leakage locations and leakage amount were exactly estimated. Various leakage amount from 0.0005
m3/s to 0.0018 m3/s were reproduced and leakage location was detected by back tracing calculation method. It was verified that back
tracing calculation method as a leakage detection method is effective.
