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. problem_statement: The problem is to determine water quality in a water distributor network as a function of time and location. The mathematical problem can be visualized (vaguely) as a system of equations that describe the spatial and temporal transport and dilution of a contaminant injected at a specific location. date: 1999 date_type: published pages: 11 citation: Stockie, John (1999) Contaminant Transport in Municipial Water Systems.
