Hydrology tools: missing help. Where/how to get it?

Hi everybody, I'm trying to build synthetic drainage lines as coincident as possible with the "real world" shown in the cartography. I think that is a basic purpose of everyone performing hydrological analysis of natural areas, right? 1st I used ArcGIS without the help of ArcHydro and the results were simply unacceptable! (My area has a… (Show more Show less)

ArcHydro doesn't output to shapefile

Hi, all - I just spent way too much time debugging something that I probably should have known, so wanted to post it here in case it saves someone else time. In a nutshell, ArcHydro does not output to shapefiles, only geodatabases. And if you specify a shapefile as the output to something like Batch Watershed Delineation, you get an error like… (Show more Show less)

Hi all, I am currently working on analyzing topographic data collected over a span of 3 years on the same stream reach.

I am using the 3D Analyst extension and the "Interpolate Line" function… (Show more Show less)

HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.6

Hello! I know there is a version of HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.5. I need these two plugins for ArcGIS 10.6. Does anybody know where I can find such versions? I searched in this link, but for version 10.6 doesnt exist yet. Do I have to downgrade the arcgis version? http://downloads.esri.com/archydro/ Thanks

stream to feature - how to add Directionality to attribution?

Using the Stream to Feature tool, results an output of line segments that shows which direction each cell is flowing. See attached image. The computer knows these values - it created them as a Flow Direction Grid (see attached explanation) - but they do not appear in the Stream-to-Feature attribution. I can symbolize these line segments - and… (Show more Show less)
