Does a version work with ArcMap 10.3 or 10.4?
HEC GEORAS 10.3 is released yellow.esri.com - /archydro/HecGeoRAS/
Not sure if it would work smoothly with ver. 10.4
Edit: It might not work with ver. 10.4, as issues faced by the users run hec-georas with arcmap 10.4 , in which case you might have to wait for its 10.4 release.
Thank you. I've been trying to find it without any luck. Unfortunately it won't install with 10.4.
