Is anyone able to tell me what they think is happening here??? Why is the water “floating” in the downstream sections?? Thank you very much in advance!!
I don’t use 3D views in HECRAS so much. Could it be a setting toggled?
Maybe try examining the other result viewing options: cross-sections or profiles. The blue could be the area of the water shaded, or it could be just the top of the water surface shaded.
