Leak location in water distribution networks based on dynamic tests and parametric identification

The paper deals with the problem of locating leaks in water distribution networks with many nodes and branches. The pressure transients measured in a few selected nodes, in response to pressure variations applied to one node, are analyzed by a detection and isolation algorithm, based on parametric estimation of faulty network models. The algorithm is tested by simulation in a realistic case, giving promising results.
