- Abstract:
- Water quality safety is a top priority in water supply management. Once abnormality of water quality of the pipe network is found, corresponding pollution checking procedure should be started immediately to clean up the pollution sources as soon as possible. In the present work, a particle back-tracking algorithm (PBA) was proposed. It could be used to back track the path of water according to water quality abnormal information of monitoring points downstream, and help finding the possible pollution source location. Meanwhile, a program was developed based on PBA algorithm, and it was integrated into the existing real-time hydraulic model. The program was applied to deal with an abnormal turbidity event in a real-life water distribution system, in which good performance was achieved.
