Computational Methods for the SWMM5 Model in InfoSWMM and InfoSWMM SA

Computational Methods for the SWMM5 Model in InfoSWMM and InfoSWMM SA

InfoSWMM and InfoSWMM SA is a physically based, discrete-time simulation model. It employs principles of conservation of mass, energy, and momentum wherever appropriate. This section briefly describes the methods InfoSWMM and InfoSWMM SA uses to model stormwater runoff quantity and quality through the following physical processes:

  • Surface Runoff
  • Infiltration
  • Groundwater
  • RDII
  • Snow Melt
  • Flow Routing
  • Surface Ponding
  • Surcharging
  • Inlets
  • Water Quality Routing
