1. SWMM 5 has DWF enter at a node and ICM has DWF as part of the Subcatchment Loading
2. Thee Import and Export From ICM needs manual adjustment of the DWF
3. One way to do this is to make an ICM CSV file to import the DWF Section of SWMM 5 (Figure 1)
4. Which allows you to manipulate the flow DWF in SWMM 5 to the population based DWF in ICM and IWCS.
Here is one example
hw_subcatchment, S012-010 ,4.14841
hw_subcatchment, S005-006#1 ,7.8094
