Sensor Placement Strategy to Localize Leaks in Water Distribution Networks with Fluctuating Minimum Night Flow

Small leaks research has attracted researchers for many years due to the impact on economy and environment. The challenge of small leaks detection due to its characteristics that tend to be undetected requires sophisticated method by involving the collaborations of sensor readings. This challenge is even harder in pipeline network with fluctuating minimum n ight fl ow (M NF) in a District Metered Area (DMA). We propose a method that uses the lean graph to place sensors and use the readings to detect and localize small leaks in such situation. Experimental results indicate the lean graph is reliable in finding strategic sensor locations to detect a nd localize leaks.
