Methodology for leakage isolation using pressure sensitivity and correlation analysis in water distribution systems

Abstract

In this paper is presented a novel leakage localization approach that is calibrated on real networks. Leakage positions are usually inferred by measuring pressure in a certain number of the nodes of the network. Since pressure sensors are quite expensive, only a few number of them is available. As a consequence, the effective arrangement of them turns out to be a not trivial problem. The study is devoted in performing an analysis of the sensitivity and correlation of the network in order to extract the best measurement points (i.e. nodes).
