Here are the steps to connect a River Mesh Polygon at a fixed culvert level so that the culvert does not have to be full to have inflow from the 2D Mesh.
Step 1. Define the Culvert Type with Fixed losses
Step 2. Define a Mesh Polygon … 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
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:
1. SWMM 5 Non Linear Reservoir and SWMM in ICM
2. Snyder and Clark Routing… Read the rest
| Boundary Type | 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.
Available types 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

How to Make Break Nodes in #INFOSWMM and #InfoSWMM SA
You would add a break node to break up long force mains so that the pipe(s) react faster to the pump flows.
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
