Abstract

The numerical hydraulic simulation of pipe networks calculates the heads and discharges at the 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 the 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 in trying to detect the source of contamination within the pipe network. We assume a 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 the inverse source detecting procedure. The inverse source detection procedure is shown and verified on an experimental model.
