Abstract: Transient wave-based leak detection methods have been extensively developed for urban water supply pipes. However, they might become inaccurate in long pipes due to their large diameters and long lengths. In this paper, the transient wave reflection (TWR) method is used in long water conveyance pipes to specifically localize a leak anomaly both numerically and experimentally, with wavelet transform used to identify the reflected wave in noisy environment, and to determine the leak detection range. As a results, the TWR produced accurate localization estimations.
