AbstractLeaks are detrimental to any water distribution system and hence are an immediate concern to the human society. This paper proposes a transient analysis for leak detection with leak and no leak scenario by using Surge2000 to detect leaks in a pipe. MATLAB has been used to perform inverse transient analysis to identify the location of the leak. An experimental setup is modeled according to the standard setups and is calibrated by simulation under different scenarios in a Surge2000 platform hence replicating the standard setup. Leak detection was performed with sections under known locations thereby verifying the algorithm. The results are truly appreciable and prove the efficiency of the method. [1] F. Colebrook and C.M.
