Thanks for your feedback.

I even tried changing from SI to US units (just to check if it was a bug) but nothing. It doesn’t change anything in profile, and velocity are about 1.5 m/s, so with a unitary coefficient I should see a 0.11 m headloss.

I’ll experiment more and write here if I have news.

Thanks for the answer Chris.

I finally ended up using a rating curve BC, from zero flow to maximum flow capacity (so not for the entire height of the section). That gives me the results I expect, even though I’ll have to edit it if I decided to change roughness. All in all it works.

I think I didn’t explain myself well.

The K I’m referring to is the coefficient in the minor losses menu, under table menu in the geometry editor. This coefficient should be multiplied for the kinetic height of the section and included in the energy equation, to model minor losses caused by bends or other localized headlosses.
My problem is that is not working at all, since Water level stay the same whatever K number I input.

Hope it’more clear now.
