Peter, I thoroughly enjoy your discussions and posts. I took a certification class back in 2004 which was a two-day seminar. Best learning experience ever!
On another note, I am modeling a compound weir for my outlet structure, with both discharging through the primary culvert barrel, Device 1. I would like to know if the program discerns between weir flow and orifice flow? I do see the report stating that the outlets are limited to weir flow as low heads. Does the program calculate this automatically and also am I able to model my weir outlets as "orifice/grate" as opposed to a sharp crested weir. Does this make a significant difference in my total outflow. Please see attached example.
Note: I also have my calculation settings to dyn-sto-ind mode to take my headwater and tailwater into effect considering my culvert pipe is discharging into an existing pond.
In summary, I am concerned that I should be modeling my outlets as weir flow separately.
Much Thanks, Martin Finch Jr, EIT
