You'll need to fix them and run the model again.ģ) Make sure you have saved your project after running the model that you want to map. In this case, RAS Mapper should report which cross-sections are producing the errors in the lower left panel. as a result of interpolating cross-sections over a coarsely resolved channel). Errors can happen here if you have some cross-sections which don't intersect the river centreline (e.g. Regarding RAS Mapper crashes – here are a few troubleshooting strategies.ġ) After doing a model run, don't change your geometry before using RAS Mapper - this can cause a crash.Ģ) Check that you can generate the interpolation surface. Hello… I have got some results from HECRAS, for instance, depth, velocity,etc…But they are not having unit like 150 meter, feet,etc…can any one suggest me. Do you know anyone with ArcGIS that can convert it for you?ĭoes anybody of you has the same problem that RAS Mapper crashes while generating layers and might have anybody a solution for this? Thanx It cannot be generated in the RAS Mapper (yet).īeing that I am limited/stuck with using Microstation Inroads and no GIS software is there any way to convert the info in a. It can be generated in ArcGIS or other GIS applications. flp archive? I use Hec-GeoRas to introduce geometry into the models, but I don't be able to export the bynari file requested by RAS Mapper. Alternatively, the RASMapper can do a lot of this completely within HEC-RAS. To do this, you need to have ArcGIS, spatial analysist, and 3d analyst, as well as GeoRAS.

I believe what you saw was made with GeoRAS within ArcGIS (or ArcView). The HEC-RAS website demonstrated a animation of 'Flood inunation', show dynamically showing the inundation area, and the text said it is made by using HEC-RAS. In previous versions of RAS, you had to use HEC-GeoRAS, which is an extension to ArcGIS to create your floodplain maps (or other expensive 3rd party software apps like RiverCAD). You can simply open the shapefile(s) created in the RAS Mapper and 'edit away' in your favorite GIS software application. The nice thing for AutoCAD users (or other GIS software users) is that you are not forced to use ArcGIS now. Although I think the idea is that HEC will, over time, add more and more GIS editing capability to the RAS Mapper. Any smoothing of the floodplains or other advanced GIS editing techniques will still have to be done in GIS software. I am looking forward to the increasing ability to work with GIS info directly in RAS. I was thinking to myself, 'I wonder if anyone has started a blog devoted to HEC-RAS?', and one Google search later, bingo. I'm guessing you's still need ArcGIS to edit your floodplains? Yeah…me too! But this RAS Mapper looks very cool. Great inside scoop, Chris! I hope they'll fix some of the other buggies in it 🙂
