A collection of various versions of SWMM 3 and 4. WCH_2004 is the last version developed by Wayne Huber at OSU in 2004 before the 1st SWMM5 release
and code for SWMM4.99 by CDM Pittsburgh (as of 2004)
This is the data input file for a CDM/CDMSmith Pittsburgh versionSWMM4 model from 2000 to 2004. It has additional capabilities beyond SWMM 4.4 and was made as a bridge between SWMM 4 and SWMM 5, thus the 4.5 number.

Here is a graphical view of the nonlinear runoff processes in InfoSWMM and SWMM5:
1. Three runoff surfaces
a. Impervious with Depression Storage
b. Pervious
c. Impervious without Depression Storage
2. Slope (same for all runoff surfaces)
3. Width or the Dimension of the Subcatchment (same for all runoff surfaces)… Read the rest
