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.

I'm currently using SWMM V5 to model the drainage network for a small urban catchment.
There are a few side entry pits along the road—these pits capture road runoff.
I was wondering, is there a way in SWMM to specify the inlet capacity

Attached is a simple sample snowmelt model in SWMM 5 that has built in snowfall and temperature in a one subcatcment model with snowmelt. You define the separation of precipitation into snowfall and rainfal
Subject: Example Groundwater Model in SWMM 5
The attached model shows three ways in which the groundwater model of the SWMM 5 subcatchments interact with the node depths of the hydraulic network. The hydraulic network interaction can be either:

This example was created from an older SWMM 4 model from 1988 using the SWMM 4 to SWMM 5 converter. The values for the coefficients in this case are A1 = A3
Subject: SWMM 5 Leaping Weir Example
The attached example shows one way how SWMM 5 RTC Rules can be used to have the low flow go down a leaping weir orifice and the high flow go over the weir to the downstream section of the sewer.
