  7. Abstract:
  8. Monitoring of the water transmission networks is an essential factor to regard efficient, safe and economical strategic considerations. Several parameters (fluid pressure, fluid flow and fluid temperature in some cases) are measured to monitor the water transmission networks. The number and location of these measurements in deferent positions affect the cost and quality of the network states monitoring. It is obvious that measuring the all parameters and states of the network is not cost-effective even when it is possible. The conventional sensor-location methods have been developed based on the pressure variation stemmed from a leakage in the network. This study proposes a new procedure to enhance these approaches. When the locations of the sensors are found, a procedure is requisite to find the leakage location. The conventional methods for leak localization are not capable to recognize the locations of leakages when more than one leakage exist. In the current work, a new method is developed to detect whether or not there exist more than one leakages in the network. This method is also able to find the zones of the leakages when two leaks are present. To examine the performance of the proposed approaches, two water transmission networks simulated by EPANET are employed as the virtual ones. Applying the proposed approaches contributes to successful results
