Hello,
First of all this is a very great blog, thank you very much for the founder.
Question:
I am running Hec Ras analysis for 10 year and 100 year storm.
I have an hydraulic jump in only 100 year water surface elevation. In this Vicinity the proposed concrete ditch connects existing earthen ditch through CMPA pipes. The bounding culvert cross section 1, 2, 3 look good but only i have an hydraulic jump in cross section 4. How do i tackle this? I tried what ever i can by looking at previous blogs etc..but result is the same.
Question:
Due to the above hydraulic jump, what i am trying to do is put ineffective flow areas in all upstream cross sections and i see the water surface elevation going down. IS this the right way?
And also Energy gradient is way above the 100 year water surface elevation in all the upstream cross section.
Any help is greatly appreciated.
Thank you!
