Solving an inverse problem using measurements of pressure and/or flow can be used to detct leaks in water distribution systems. The study found that the location and magnitude of leaks are sensitive to the quantity and quality of pressure measurements and to how well the pipe friction parametrs are known. The overdetermined problem, i.e., more measurements than suspected leaks, was found to give the best results, but some information can be derived for the undertermined problem. The variance of leak areas indicates the likely accuracy of the results.
