The most numerically challenging sub-model to implement within Storm Water Management Model (SWMM) 5 was the dynamic wave flow routing routine known as Extran (for Extended Transport). It routes non-steady flows through a general network of open channels, closed conduits, storage facilities, pumps, orifices and weirs. In contrast to simpler routing methods, this procedure can model such phenomena as backwater effects, flow reversals, pressurized flow, and entrance/exit energy losses. Rather than simply encode a line-for-line copy of Extran, SWMM 5 restructured the code in a more readable and maintainable fashion. It also employed a slightly modified computational scheme with the intent of producing more numerically stable solutions in less time. This report documents the Quality Assurance testing program that was used to compare the dynamic wave flow routing procedures of SWMM 4.4 and SWMM 5 with one another. Before describing the tests made and the results obtained it will be useful to contrast the way in which each version of the model implements dynamic wave flow routing.
