Abstract
A method and system to localize a leak in a pipeline network include identifying a respective measured time at which an effect of a leak exhibits in a time-varying data signal measured by each of a plurality of sensors distributed along the pipeline network, each pair of the plurality of sensors defining a respective pipe segment therebetween. Estimating a time of occurrence of the leak based on the measured time associated with two or more of the plurality of sensors; and estimating a relative distance of a leak location from one or more of the plurality of sensors. Determining the leak location is based on the relative distance.
