If you are using Steady State flow and not EPS Flow you should do the following:
1. Define your Base Flow in either Load1 or Load2 for the loading manhole,
2. Select Peakable Base Flow as the Load Type
3. Define your Alternate Peaking Curve under the Tab Peaking in … Read the rest
SWMM 5 Loss Term Values for various velocities and K values
SWMM 5 has three loss terms available for each link: Entrance, Exit and Other losses. The Entrance loss uses the upstream link velocity, the Other loss uses the center link velocity and the Exit loss uses the downstream link … Read the rest

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.
