Moreover it seems that if you put a known WS BC between the critical depth and the maximum capacity height (as from rating curve, see image in first post) and after change it to normal depth BC (even without running a computation) I'm able to get correct and consistent WS in my lidded section...
Unfortunatly I don't have time at the moment for troubleshooting a new spreadsheet. Furthermore graphing and analysis capabilities of HEC-RAS are exactly what I need for my project, so this is not an option for me in this case.
However I'll add some more information I discovered. Actually this...
Hi everyone,
I'm modelling a closed conduit which has an ovoidal-like cross section with hec-ras. I'm interested in steady flow, open-channel (not pressurized, at least not for the most part of it) analysis. I modelled the conduit as a lidded cross section. At the moment I just put 3 identical...
