This is a story about two inp files. It shows the continuity in stormwater modeling from 1980 to 2025 onwards. It is about Extran1 (free outfall) and Extran 2 (fixed backwater with a tide gate) from the 1981 Extran Manual. This compact test case, born in the era of punch … Read the rest

The Many Avenues of Ruby Help in the ICM Online Help File—Hint for AI Usage
1/ Ruby Introduction In the ICM Online Help File You can print any of these pages and use them with most of the AIs. Or copy and paste the
While recently organizing my garage, I discovered an intriguing poster I'd created comparing the 1D St Venant Terms between SWMM4 and SWMM5. Originally crafted in Microsoft Publisher for the 2007 Urban Runoff Modeling Conference at Humboldt State University, this poster presented a compelling analysis of hydraulic solutions. Though the original … Read the rest
Why a Hot Start File important in InfoSWMM and InfoSWMM SA, SWMM5
A Hot Start File in InfoSWMM InfoSWMM SA is important as it provides initial depths, initial flows and initial settings for the hydrology and hydraulics features of the SWMM 5 engine. You have three options:
Simple SI Unit Model for SWMM5 LID with 100 mm Rainfall.
Reading this blog and using the embedded SWMM 5 example file, you will run a simple SI unit model based on factors of 1 and 10.
… Read the restThe LID (Bio-Retention Cell) is designed to have zero outflows, Figure 1,
The Reynolds Number is not shown in SWMM 5 of InfoSWMM but can easily be added to the SWMM 5 code as shown in Figure 1. The equation for the Reynolds Number is
Normally, as shown is Figure 3 the Reynolds number is is very high and is indicative of … Read the rest

3/ Storm Water Management Model Climate Change Addon
The purpose of this note is to show how InfoSWMM is related to various SWMM 5 engines. InfoSWMM is a ESRI Arc Map Interface to the properties of the SWMM 5 engine using model development tools created by Innovyze for InfoWater and InfoSewer. It uses a recompiled SWMM 5 engine … Read the rest
1. You use the Subcatchment, Land Use and Runoff Surface Tabs in the Subcatchment Grid (Bullet 1)
2. The Subcatchment Tab has three Runoff Areas for Impervious with Depression Storage or Initial Loss, Impervious with no
Subject: My History with Various Versions of SWMM: SWMM3, SWMM4, SWMM5, XP-SWMM and InfoSWMMI first learned about SWMM in a brochure from the University of Florida when I was just a 17 year old senior in High School. Water resources and the description of SWMM seemed to be worthy career

How To Run the SWMM 5 Console from the SWMM 5 GUI
Use the SWMM 5 tools, define the program as the DOS engine or SWMM5.EXE (1), run the tool (2) and see the dos output in the command window of Windows 7 or Windows XP. It should also be … Read the rest
Outlets in SWMM 5 can have reverse flow
Outlets in SWMM 5 can have reverse flow (1) if the downstream head is greater than the upstream head (2), a flap gate (3) will prevent the flow reversal (4). An outlet can have both positive and negative flow as long as … Read the rest
Stopping Tolerance in InfoSWMM, H2OMAP SWMM and SWMM5 Internal Units
InfoSWMM, H2OMAP SWMM and SWMM 5 share the same underlying dynamic engine code but one small difference is that InfoSWMM and H2OMAP SWMM allows the user to select the node stopping tolerance instead of always using the default SWMM 5 … Read the rest
Importing a Link Shapefile into InfoSWMM via GIS Gateway
Here is how you map the shapefile pipe fields to the InfoSWMM data fields. One note, you had two diameter fields (feet and inches) and the feet column was mostly zero so I used the inch column. Here are the four … Read the rest
