I am using HEC-RAS 5.0 RAS Mapper to develop a velocity grid. The velocities on the raster are much lower than my average channel velocities however. Anyone know why it is doing this?
It doesn’t seem to matter how much I discretize the horizontal or vertical points along my HTab curves or how many flow distribution locations I use.
I have my own update, in case anyone has the same issue. I checked with someone at USACE and it sounds like this may be a bug when using metric units. The issue has been passed on to HEC.
