Subject: What are the Types of Force Mains (FM) in SWMM 5?
There are five ways to model a force main in SWMM 5 for the combination of full and partial flow in the force main (Figure 1):
1. Full Flow using Darcy-Weisbach for the friction l

If you are using the SWMM 5 Rainfall Dependent Infiltration and Inflow(RDII) feature you can also use the RDII storage parameters to change the RDII runoff by simulating the storage in the Sewersh
Read more…There are Four factors in Rainfall Dependent Infiltration and Inflow or RDII in SWMM 5:
1. The fractional response to Rainfall or R from 0 to 1
2. The Time Base of the Unit Hydrograph or T in hours * Dimensionless K Shape Factor
3. The Sewershe
