I think this is what I have been looking for:
Horizontal Weir Flow
For horizontal weirs, flow is first calculated as if the weir is vertical and rectangular, using the
perimeter of the weir as its length. Then a second calculation is made assuming orifice flow based
on the cross sectional...
What I would normally do is treat the top of the inlet as four vertical weirs with end contractions up until the the flow rate starts to decrease instead of increase and then treat the opening area as an orifice. How about this approach? That works fine for square or rectangular inlets, but how...
That was helpful information for vertical weirs, but my problem is with horizontal weirs. Do you know the equation(s) for flow through horizontal weirs?

It also refers to fore mains, not just gravity lines.
The difference is, the velocity at the operating point in the forcemain should be at the self cleansing velocity.
