The InfoSWMM Risk Assessment Manager is organized by risk assessment tasks. The risk assessment drop-down menu contains four commands. Each of these commands opens a new dialog box for further input. The following sections describe the functionality for each of these commands. Generally, these commands … Read the rest
The Create Shapefile tool available from the GIS Gateway, allows you to create a new ESRI® Shapefile directly from InfoSWMM data. Any data associated with each data type can be used to populate the new Shapefile attribute table. The tool can be applied to … Read the rest
Note: The variable time step option is a powerful feature of SWMM5 as it lets the engine determine the CFL time step needed for each time step (1). A good guide is to use a maximum time step 2 to 5 times bigger than the average time step during a … Read the rest
Select a Boundary Type for the 2D Boundary polyline. Boundary type effects what happens to the flow when it reaches the boundary. Note: If it is not clear what happens at the boundary then Critical Condition type is recommended.
How to Easily Use the DWF Allocator with your Lots Shapefile in InfoSWMM
The goal of this document is to show how you can use a shapefile with polygon loadings to a link in the InfoSWMM DWF Allocator to create DWF loadings to the nodes in InfoSWMM that are the … Read the rest
The SWMM5 engine uses mean flow as the dry weather flow value (DWF) and not population but does allow weekday, weekend, daily and monthly patterns. You can use these many pattern options to actually use population in the SWMM5 and InfoSWMM dry weather flow tables. Here are the steps as … Read the rest
Normally in flow routing, when the flow into a junction exceeds the capacity of the system to transport it further downstream, the excess volume overflows the system and is lost. An option exists to have instead the excess volume be stored atop the junction, in a ponded … Read the rest
InfoSWMM and InfoSWMM SA offer an advanced RTC rule that could be used to effectively simulate the operation of pumps and flow regulating structures such as weirs, orifices, and outlets. Unlike Simple Controls, RTC rules allow for the creation of multiple conditions to be … Read the rest
Tutorial 2 Optimizing Rain Barrels for Sustain 4.0
This example shows the importance of a treatment train, the percent imperious draining to the LID's on a Subcatchment, the importance of optimizing for the number of units, area and soil thickness. Sustain will optimize the number of Rain Barrels on the … Read the rest

I have noticed based on email questions and postings to the SWMM LIst Sever (a great resource hosted by CHI, Inc.) that many SWMM 5 users do not know about the really outstanding documentation on SWMM 5 posted on the EPA Website https://www.epa.gov/water-research/storm-water-management-model-swmm It consists of two now and in the near future three volumes on Hydrology, Water Quality, LID’s and SuDs and Hydraulics. The documentation is fantastically complete with detailed background on the theory, process parameters and completely worked out examples for all of the processes in SWMM5. It is truly an outstanding aid to modelers and modellers worldwide. It would benefit you to read them (if you have not already downloaded the PDF files). Thanks for reading this post
