This table outlines the core concepts and methods used in the dynamic wave solution of SWMM5, InfoSWMM, and ICM SWMM, assuming a similar approach across the three unless otherwise specified by their respective documentation. Each version may have its own set of features, enhancements, or differences in the implementation of these methods and equations.
