Abstract
In one embodiment, a hydraulic simulation model corresponding to a real-world hydraulic network is loaded in a hydraulic modeling and simulation application executing on a computer system. The hydraulic simulation model represents leakages as pressure dependent emitter flow at selected nodes (leakage nodes). Optimization criteria include a specified maximum of possible leakage nodes. A genetic algorithm (GA) generates trial solutions for an optimization, each trial solution representing locations for leakage nodes and corresponding emitter coefficients. A hydraulic analysis is performed for the trial solutions to generated model-simulated results. The model-simulated results are compared to field-observed data for the real-world hydraulic network to generate goodness-of-fit values. The process is repeated until a particular goodness-of-fit value is achieved or a maximum number of iterations is reached. Predicted locations for leakage nodes from a particular selected trial solution are then displayed to a user.
