Hello, I want to ask, does in HEC - Ras (version 3.1.3) somewhere exist a summary table, where are all of important elevations written? (I mean elevation for example of channel, ROB, LOB) Thanks for your answer.
I'm running HEC-RAS 4.0 Beta, but I think the layout of the program is the same as the version you are running. After you've completed a run, from the main program menu, there are buttons at the top. The button 3rd from the right "view summary output tables by profile" will pull up a summary table. From that table, up where it says "Standard Tables" you can select a variety of tables that will sutie your needs.
For summaries by cross-section, from the main program menu, hit the button fourth from the right "View detailed output at XS, Culverts, ...". This will give you the geometry, mannings, flows, velocities, etc. for each cross section.
