|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:

What if the percent routing is 100 percent?
- If you choose outlet only as the subarea routing both impervious areas and the pervious area go to the outlet node or the outlet Subcatchment
- If you choose pervious as the subarea routing 100 percent of the impervious areas will flow to

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
