Abstract

Detection and location of contaminants in a water system is important for preventing poisoning, determining the nature of the contaminant, fixing pipe leaks, and finding parties responsible for illegal or accidental discharge. Direct and inverse models are proposed in this paper for quick computation of the origin of contaminant location and its propagation through the water utility network. The direct model builds a composite of solutions for each pipe segment and algebraic equations for the boundary and initial conditions for the branch points. The algebraic equations for determining the distribution of contaminant at branch points are analogous to the current distribution for electric circuits. Each distributed mass is part of the initial condition for the contaminant transport equation in a pipe segment. 1 Introdu
