HEC-RAS Cross Sections
HEC-RAS Cross Sections
(OP)
I have a very flat flood plain with a farmers ditch as the main channel. The channel travels north then bends 90 degrees West. What do you do when the sections overlap? What do you input for ROB and LOB reaches? Any help would be greatly appreciated. Thanks in advance.

I don't fully understand bending the cross sections? Is there a tutorial floating around that I can look at regarding that? How do you let the program know that there is a bend in the cross section? Thanks in advance.

I have seen people just cut cross sections straight across a channel regardless of whether one side was sloped differently than the other which distorts the length of the cross section and thereby the area.
