Underground Water Leakage Detection Using Magnitude Squared Coherence

Underground water distribution pipelines periodically lose a significant amount of water transmitted through them. Multiple technologies have been developed throughout the years to help identify and locate leaks within underground water distribution networks. Acoustic leakage detection technology is considered in this research. A novel approach is introduced to build an adaptive filter that can be used to filter out the leak sound, using Magnitude Squared Coherence (MSC) function. This can be used to make the existing leakage detection procedure feasible under noisy conditions.
