This is a collection of actions I've learned to take when I'm having problems with ArcHydro or HEC-GeoHMS. I'll add to the list when I find more. Make sure the Geoprocessing extents include the whole project: Go to the Geoprocessing menu>Environments...>Processing Extent. Under Processing Extent choose a layer that you know covers the full extent…(Show moreShow less)
I am using arc hydro 10.1 and there are some solutions to these error which works for me - define workspace location and processing extent in c drive - Whenever you have to use arc hydro, always define a geodatabase then start using the tool - always delete the temp files. May be this will help.
I just installed the Arc Hydro Tools 10.1.0.366 on top of Desktop ArcMap 10.1 SP1 Build 3143 with Spatial Analyst. When I go to the "Stream WSE From Point WSE Measurements" model tool, it is not available. It has a little red "X" over it in the Catalog Toolbox view. I thought I should have access to this tool because I do have Spatial Analyst…(Show moreShow less)
Hi, I have downloaded the arcgis version 10.4 and I need the Archydro tool to work on it. Does anyone knows if there is a version of archydro for arcgis 10.4? Or do i need to download other version of Arcgis? I thought wierd because I got Arcgis from free trial on esri and they gave me version 10.4 and for other friends who did de same, other…(Show moreShow less)
Do you know why the most recent version (10.4.0.24) is dated later than version 10.4.0.3? Hmm, it is not. 10.4.0.24 was built/posted 2016-12-27, 10.4.0.3 was built/posted 2016-06-02--simply that the sort order on the web page is *not* by date. Rather it is an ASCII sort of the folder name--last column is the version and 24 comes before 3.
I need to find the distance (from sampling points on a stream network) downstream to the mouth of a watershed using NHD flowlines and/or a DEM. I do not know how to use code. Thanks for any help on this!
Hi all, I downloaded and installed ArcHydro for ArcGIS Pro from this link: yellow.esri.com - /archydro/archydro/Setup/Pro/ , but none of the tools work and there doesn't seem to be in usage guidance aside from the installation read me file. Was anyone able to get this working? I'm looking to update to 10.4 and until an ArcHydro version is issued…(Show moreShow less)
Is the flow accumulation tool in ArcHydro the same as the flow accumulation tool in the spatial analyst toolbox? The ArcHydro one is taking a very long time to run, and I'm wondering if the spatial analyst one will do any better. I'm using the tool on the BowlFDR, following along the steps in the ArcHydro tutorial, for Warren County, KY. The file…(Show moreShow less)
I am trying to create catchments for the high resolution NHD stream network and a 10m DEM in the entire state of Texas. So far, I have been processing the Fill Sink operation for 21 days and it still has not completed. I am looking for a way to break the state apart and run small areas that I can then splice back together and still be…(Show moreShow less)
Running ArcGIS 10.5 with 10.5 ArcHydro. Everything is working fine with the various GP tools until I get to time of concentration in H&H Modeling. Running the tool on my dataset generates the Error 010043 "All selected cells are at absolute barrier." at the step where it creates the maximum length flow path. It stops when creating the flow path…(Show moreShow less)
The work-around is to first create the Longest Flow Path in the Watershed tools. Then use the Computer Time of Concentration for Longest Flow Path tool. This correctly populates the flow path and catchment basin feature classes with the time of concentration.
