Development of a novel mathematical model for leakage detection and localization in the water distribution system: based on the modification of the hydraulic model.

As a result of contamination intrusion's inherent vulnerability, water quality security has been an important issue within water distribution systems (WDSs). In order to detect (un)intentional intrusion events in a timely/effective manner, intensive studies have been undertaken to identify leakage detection and localization methodologies. It is possible to detect and localize leaks in water distribution systems using models-based methodologies. The purpose of this paper is to propose a novel leakage detection and leakage localization model that is based on the network hydraulic model. In order to solve the leakage problem, all hydraulic relationships have been modified and a new model has been developed. This model is developed based on head variation of network sensor nodes. This study utilized mathematical modeling based on the response surface methodology to detect leakages, in addition to detecting leaks; this method can also be used to assess the location of sensors. Consequently, in addition to developing a novel model, a new method is presented for assessing sensor placement in the present study. A leakage diagnosis benchmark dataset is used to demonstrate the proposed methodology and evaluate its effectiveness. Based on the final results, the presented method performed well and was highly accurate. [ABSTRACT FROM AUTHOR]
