Contaminant source detection in water distribution networks

Numerical hydraulic simulation of pipe network calculates heads and discharges at inner points of pipes and other non-pipe elements of the network. Besides these calculations, contaminant and solutes spreading in the pipe network can be of interest too. The contamination spreading through water-distribution pipe networks is controlled mainly by mixing properties at pipe junctions. Real mixing that can occur within a pipe junction lies between the complete-mixing model and incomplete-mixing model assumptions. In this paper we demonstrate the inverse modeling trying to detect the source of contamination within the pipe network. We assume scenario where contaminant concentrations are measured in one, two or more nodes of the pipe network. These results are used as a starting point for inverse source detecting procedure. Inverse source detection procedure is shown and verified on an experimental model.
