“…To assure objectivity, the accuracy of the proposed model is also validated by qualitative evaluation with measures in the Table 4. The applied stochastic measures are Correlation Coefficient and Weighted Integrated Factor (WIFac) (Twisk, Spit, Beebe, & Depinet, 2007). WIFac is a measure to judge degree of match between two data groups.…”

Leaks in water distribution systems should be detected to avoid economic, environmental, and social problems. Existing Bayesian Inference based time-domainreflectometry (TDR) methods for leak detection have a limitation for real applications due to the lengthy time in building sample data. As the pipeline distance becomes longer and multiple leaks must be considered in long distance pipelines, the computational time for building training data gets larger. This paper proposes a scattering-parameter-based forward model to relieve computational burden of the existing TDR methods. It was shown that the proposed model outperformed the existing RLGC-based forward model in terms of computational time. The proposed model that is combined with Bayesian inference and TDR signal modeling is validated with an experimental pipeline, leak detectors, transmission line, and TDR instrument for leak detection. In summary, the proposed method is promising for leak detection in long pipelines as well as multiple leaks.
