We have a 2D mesh which includes a number of embankments. These have openings through them which would ideally be modelled as culverts with culvert entry/exit losses, however this doesn't work as the culvert outlet link requires another link downstream, and I want it to discharge back onto the 2D mesh.
The culverts are likley to be freely discharging in normal conditions but surcharged in large events.
Am I missing something or is there a better way of doing this?
