Contaminant Transport in Municipial Water Systems

Abstract

Our first task from CHAL was to examine the dynamic (forward) algorithm used in the software package EPANET, and ensure that it is computing physically reasonable solutions for networks that experience rapid "flow reversals", in which the flow in a pipe section changes direction over short time intervals.

We begin with an overview of the physics of flow in water distributor networks, and the implementation used in the EPANET flow solver. The bulk of our results from the workshop are concerned with analysing simple flow networks and using the results to draw conclusions about the well-posedeness of both the forward and inverse problems.
