Hydrology: Checking Channel Cross Sections
Hydrology: Checking Channel Cross Sections
(OP)
I need to check my cross sections produced by HEC-RAS.
What formulas needed to decide the water surface in
a cross section based on a steady state analysis, typical
manning's n for banks and bottom, etc.
What my real goal is...to manualy plot the cross sections
in autocad so I determine where my flood limits along
a flow line. If anyone can help please do...yah, I do have the national engineering handbook, urban hydrology, hec-ras, hec-hms, manuals....I just want some help without digging into a whole lot of detail.
Thanks.

Its a natural channel, (yah, I know, a steady state is not
very logical, but that's what I want)...I is typical brush,
earth, rocks, etc.
