This blog contrasts the St Venant Solutions for InfoSewerH20Map Sewer (1), InfoSWMM/H2OMap SWMM and ICM/ICM SE. 1.  Assumptions for the St. Venant Equations The assumptions behind Lumped and Distributed Models along with the assumptions of the  St Venant equations .  InfoSewerH20Map Sewer, InfoSWMM, H2OMap SWMM, SWMM5, ICM and ICM SE are all Distributed models for Unsteady flow.  InfoSWMM and InfoSewerH20Map Sewer have options for direct steady flow.  ICM and InfoSWMM can also use a quasi steady flow solution.   All of these Innovyze models use the Continuity Equation and Momentum equation for routing flows in links.  The numerical solution differs between the three Innovyze main  platforms: InfoSewer and H2OMap Sewer InfoSWMM,  H2OMap SWMM and SWMM 5 ICM and ICM SE Continuity Equation Various Forms of the Momentum Equation 2.  Muskingum-Cunge for InfoSewerH20Map Sewer The continuity (mass conservation) equation is: where x ...
