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 4.99 number.
Designed in response to the needs of watershed and stormwater engineering professionals, InfoSWMM Sustain performs very sophisticated hydrologic and water quality modeling in watersheds and urban streams and enables users to develop, evaluate, and select optimal best management practice (BMP), Low Impact Development (LID) and Sustainable Urban Drainage Systems (SUDS) … Read the rest
A quick note: A really nice feature of the way #SWMM5 models water quality is the easy ability to model tracers for the contribution of the major processes. You can set up a concentration of 100 (for example) for DWF, RDII Flow, Runoff and Groundwater to find the percentage contribution … Read the rest
One of the most powerful InfoSWMM, InfoSWMM SA 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 … Read the rest

How to Model and Display Peaking Factors in InfoSWMM
A significant difference between InfoSewer/H2OMap Sewer and InfoSWMM/H2OMap SWMM is how peaking factors are applied to the dry weather flow (DWF) at the nodes. InfoSewer has unspeakable and peakable flow with the peakable flow equation defined in the peaking tab of … Read the rest
You may have noticed, that in some instances, the Pipe full capacity value on a pipe in #SWMM5 is less than the maximum simulation flow in a surcharged pipe. How can there be more flow in a … Read the rest
How to See the Highest Continuity Errors Table in the Output Report Manager
In the output text report file of InfoSWMM and InfoSWMM SA there is the Highest Node Continuity Error Table. The Table shows the highest 20 Nodes for percent node continuity errors and the actual continuity error as
Based on email inquiries and postings to the SWMM LIst Sever (a fantastic resource hosted by CHI, Inc.), I’ve discovered that many SWMM 5 users are unaware of the excellent documentation on SWMM 5 available on the EPA website at https://www.epa.gov/water-research/storm-water-management-model-swmm. It is divided into three volumes: Hydrology, Water Quality, LIDs or SuDs, and Hydraulics. The documentation is fantastically complete, with detailed theory background, process parameters, and fully worked out examples for all of the processes in SWMM5. It is truly an outstanding resource for modelers and modellers all over the world. It would be beneficial for you to read them (if you have not already downloaded the PDF files).
