Note: How Dry Weather Flow is Used in InfoSWMM at a Node
There are four components to the Dry Weather Flow (DWF) in InfoSWMM:
1. The mean flow in user units at the node,
2. The DWF Allocation Code – if you are using the DWF Allocator
3. The Pattern for Weekday, Weekend etc for the mean flow.
The data is entered or entered for you in the Node Inflow Icon or the Operations Tab of the Attribute Browser
