This manual provides the fundamentals for using the SWMM5+ hydraulics engine coupled to the the US Environmental Protection Agency's Storm Water Management Model (EPA SWMM). SWMM5+ provides a finite-volume solution for the dynamic wave equation (Saint-Venant equations) that replaces the link-node finite-difference approach in EPA SWMM. The principal advantages of the new model are (i) improved mass conservation and stability and (ii) efficient use of multi-core processors to reduce computational time for large systems. This manual assumes users are already familiar with EPA SWMM and have the EPA SWMM user guide available for reference.
