Separate boundary condition

[igorce]

Hello,
Please for your opinion, comments and guidance on the issue:
1. Why are getting an unrealistic hydraulics?
2. Can be placed boundary conditions in any section (in that section which i want)

Please see the picture and i wait comment!
Thanks in advance

Are you getting any warnings or errors stating cross-sections are defaulting to critical depth?

I was get warnings, not errors. In continue i share you print screen !
Thanks in advance if you can halp me

I’m still waiting for answers or comments.

Is it possible no one can answer the questions?
Is there a possibility to set boundary conditions in each section?
How can we solve the problem of illogical flow?

The warnings you are getting are causing some of the problem. The first warning is telling you that the program did not solve for that cross-section and used critical depth for the answer. The second warning is similar. The third warning is stating that the change in conveyance between the two cross-sections is to large and may need more cross-sections. The fourth warning states you may need more cross-sections.

Basically you may need to add/remove cross-sections, adjust roughness values, or modify cross-sections to fix the problem.
