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.

This is part of the #Inside_#SWMM5 series of blogs and is intended as a visual aid and code developer for the Storm Water Management Model Reference Manuals on https://www.epa.gov/water-research/storm-water-management-model-swmm I always think images (and some words) are best at explaining the internal working of code. I do encourage you to … Read the rest
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
One of the most powerful InfoSWMM and H2OMAP SWMM Application Tools from Innovyze is RDII Analyst. RDII Analyst will separate out the Groundwater base flow, Dry Weather Flow (DWF), DWF Patterns, estimate the Wet Weather flow component or RDII Rainfall -Derived Infiltration Inflow (I&I) and use a Genetic Algorithm to … Read the rest
