Corey:

We reviewed your StormNET project file and observed that the inlets (on-grade) which are giving you problems have three outlet links. Presently StormNET supports only two outlet links for on-grade inlets. One stormwater sewer pipe and a bypass gutter link must be defined for on-grade inlets.

In your model, Inlet-1 has two outlet links as "Bypass-1" and "Con-1". However, in addition, this inlet has also link "Con-10" connected between the "Inlet-1" and "Inlet-10" which has an adverse slope. As this link has an adverse slope, it becomes an "outlet" link for Inlet-1 (although it is defined as an "inlet" link).

StormNET can have inlets with adverse sloped stormwater pipes. However, presently StormNET does not support on-grade inlets with more than two outlet links. We have asked our development team to see if they can add support for this situation.
