By Autodesk Technologist for ICM/SWMMThe overland flow junction does have an invert and rim elevation, it is usually part of a road system and you can drain Subcatchment flow to the overland flow junction. If an Inlet node is flooded the excess water can flow out of the inlet to the street through the overland flow junction. There is a virtual link between the Inlet Junction and the Overland Flow Junction.
