I was hoping there was a way to define the maps that HEC-RAS automatically produces with each run. When I'm running an unsteady 2D flow model, is there a way to have HEC-RAS produce the shear stress map in RAS Mapper in it's initial run along with depth, velocity, and WSE? It's just when I add the shear stress map layer after I've run the model, it takes almost as long to produce the shear stress map as it does to run the initial model (which for larger projects with smaller time steps can be over an hour).

Or you could extend your cross sections to cover the full area that gets wet. You could try to manually expand your floodplain by following contours in ArcGIS if you really want to do this. Outside of these areas it can't map, because it doesn't have any data to map. RAS only gets results where you have cross sections or 2D areas. If that doesn't fix it, then I'd have to see your data set to have a chance to figure it out. Try saving, closing, and reopening RAS, then run again.
Profile lines can be drawn using the Profile lines tab in the lower left hand corner of the RAS Mapper window. Yes, in Version 5.0.3 you can draw profile lines in RAS Mapper and use them as transects to extract flow data. But i would like the ras mapper to inundate everything around the river which is below WSE, even if there this place is "outside of the cross section range". However, in my model, inundation mapping is limited to where I have cross sections and it looks like ras mapper would connect the outward points of every cross section and then, only calculate the difference between the Terrain and the WSE within this "polygon". In the first picture you showed above it seems to me that the inundation mapping is not limited to where I have cross sections. I have a question concerning inundation mapping.

Hi Chris, I am trying to create a hydraulic connection between 2 2D flow areas using a weir and culvert combination in RAS 2D. The bug should be corrected in the next HEC-RAS release." I have been able to reproduce the issue here with a separate dataset and have submitted the bug to our development team. I submitted a report to and got a response last week: Is there a way to quantify how much Q goes in which direction? Any advice will be appreciated! I have several areas that show flow splits in different directions. Hi Chris, I am currently experimenting with purely the 2D modeling function of HEC-RAS. Would you mind sending a bug report to HEC on that one? Has anyone had any luck getting saved maps using the"Hybrid" water surface rendering that is new with Version 5.0.3? No matter what I set the Render Mode Option to, my saved maps (rasters, shapefiles) come out as the old "Sloping (Interpolated Values)" rendering mode.
