Parameterization and Validation of the Physical Coefficients of a WDNs by BBO

The pipeline system is the most important part of the transportation of potable water. In other words, pipes are the most important component of the water distribution system. Because of several factors, they suffer from holes in which water is lost, and therefore an economic loss to states and humanity. Responsible for the water distribution networks always try to minimize the damage. By working to find the most effective way to detect leaks in these networks. This article centers on a mathematical model of a hydraulic system that aims to locate leakage in water transmission pipes. Several optimization techniques can be used. We opted for the BBO (biogeography-based optimization) method because of its performance, in particular the execution time of its algorithm. Using this method, two parameters of the model (friction and effective flow area factor) are determined to obtain the exact position of the leak.
