A mathematical simulation model was developed for unsteady free-surface flows in urban storm sewer systems with prescribed inflows. The model is intended to serve a dual purpose--flow prediction in existing sewer systems and systematic hydraulic design of the size of the sewers of an entire sewer system. The model uses the complete St. Venant equations rather than any of their simplified forms to describe the flow in the sewers, and it also incorporates the backwater conditions at the sewer junctions. Furthermore it includes a built-in design algorithm for determination of the sewer sizes, which is lacking in all the previously developed routing models.
