How do you use an External Output File In InfoSWMM?
Step 1. Load an Output source or the hydqua.out file
Step 2. Give it a Unique Name or ID
Step 3. You now can view, graph etc. with the named output sources.
The Hydrology options in Innovyze InfoSWMM and InfoWorks ICM are shown in these mirror images map of the Runoff dialog in InfoSWMM and the Runoff Surface in ICM.
Equivalent features in InfoSWMM and ICM are:

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

Surface Ponding
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

A UH set contains up to three such hydrographs, one for a short-term response, one for an intermediate-term response, and one for a long-term response. A UH group can have up to 12 UH sets, … Read the rest
| Introducing EPA SWMM5 |
The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate … Read the rest
| Snowmelt |
Snowmelt parameters are climatic variables that apply across the entire study area when simulating snowfall and snowmelt. They include:
| · | the air temperature at which precipitation falls as snow |
| · | heat exchange properties of the snow surface |
| · | study area elevation, latitude, and longitude correction. |
