Modeling Software
 
Overview
 
Software The Stormwater Management Model (SWMM) was developed for the Environmental Protection Agency in 1969-1971 as a single-event model for simulation of quantity processes in combined sewer systems (Metcalf and Eddy et al., 1971). It has since been applied to virtually every aspect of urban drainage, including:
  • routine drainage design
  • sophisticated hydraulic analysis
  • non-point source runoff quality studies
  • both single event and continuous simulation
  • catchments of almost any size, such as parking lots, subdivisions, and cities.
The current version of HCSWMM4.31 is modified by Hillsborough County to integrate the SCS-CN method through COMBINE block with EXTRAN block.

Additional modifications:

  • Local hydraulic head loss
  • Pipe extrusion
  • Type of conduit shape 3 and 4
  • Please read User's Manual for details.
