Reach with a Weir
It's possible to specify a discharge versus elevation rating curve (Rating Curve dialog box) in the same section where I previous declare an Uncontrolled Overflow Weir? I tried to do that because I want to fix the water surface elevation above the "Minimum Weir Flow Elevation" but I can't achieve a logical result. HEC-RAS computes an irrealist value to the water surface elevation in the downstream and upstream section of the weir (section 2 and 3).
