How the inflow boundary conditions in SWMM model should be set-up for runoff modeling (I am not asking about runoff quality).
What I do is to run the model with input parameters and rainfall value, what else needed to be done.
You need to be a member of SWMM 5 or SWMM or EPASWMM and SWMM5 in ICM_SWMM to add comments!

Inflow would be:
1. Inflow Time Series at a Node
2. Subcatchment Runoff which needs Infiltration, the physical characteristics of the Subcatchment, the Rainfall
3. The links and nodes of your drainage system
If you look at the example SWMM 5 files called example1, example2 etc it may be clearer than my explanation
Thankyou Robert for your explanations.
You need to define the subcatchment data and water quality build up and washoff data. You no not need any boundary conditions but you can have initial pollutant loads on the surface.
I am not concerened about pollutant load, I am not into water quality modeling. I am designing a drainage system to handle the 10 year return period storm.
