Steps for making calibration files from the SWMM 5. Step 1. Run the model and graph at least one Object class such as Nodes, Links or Subcatchments ![]() Step 2: Use the Command Copy To to bring up the Saving Selection Dialog ![]() Step 3.

SWMM 5 Historical Setup FilesYou should always use the latest EPA supported EPA SWMM 5 GUI and engine at EPA. for your new projects. These historical setup files are for revisiting old projects. Spatial StepSWMM 3,4,5 uses a spatial step equal to the length of the link. Or, in terms of the 1D St. Venant Equation for the calculation of flow used in SWMM 5: ![]() In which is the length of the conduit.The program will calculate the cross sectional area, hydraulic radius top width and depth at the upstream, midpoint and downstream sections of the link. The link solution is pivoted on the midpoint cross sectional area in the dominant dynamic wave terms and ![]() and the non-linear term in the dynamic wave equation uses the upstream and downstream link cross sectional areas. In the finite difference equation
in SWMM 5 the pipe shown below would have one length but use the cross
sectional information from the upstream, midpoint and downstream points
of the link.The bend in the pipe would be modeled using the "other" category of losses ![]() ![]() |
