When I try to run Level DEM on the San Marcos tutorial data I get the error message: “Level DEM: System.Runtime.lnteropServices.COMException (Ox80040202): The index passed was not within the valid range. at ESRI.ArcGIS.Geodatabase.lFeature.set_ Value(lnt.32 Index, Object Value) at ESRI.APWR.ApHydro.ArcHydroOp.LevelDEM(ApLayers apLayers, lnt64…(Show moreShow less)
Was finally able to bypass this problem by using LevelDEM directly from ArcToolbox rather than going via toolbar. However, it only worked from the second attempt and on, using exactly the same files and settings. ...because ArcGIS logic.
hi, use ArcHydro occasionally but I'm not too familiar with it. I had been using Arc Hydro 10.2 with ArcGIS 10.2 for a while and recently upgraded to ArcGIS 10.4. I then had an error in running one of the ArcHydro tools (Stream segmentation tool, error was "ArcMap has stopped working") and realized I probably needed to upgrade to ArcHydro 10.4…(Show moreShow less)
Hello. I need to calculate acreage of upstream watershed boundaries from points of intersection between a proposed alignment and surface waters. I have never used the ArcHydro tools and was pointed to the from the USGS StreamStats site and was wondering the best method for getting this information. I appreciate any help - just a point in the right…(Show moreShow less)
Hello everyone. Well, it turns out the the StreamStats ended up working which saved me TONS of time. I think I must've been trying to use the application as they were finalizing v4 development because the last day I tried using it everything came together. I appreciate everyone's help and input. Thanks!
Hi All I'm one of those people who knows how to get ArcHydro to do MOST of what I need, but not all. What I want to do is to use ArcHydro to create catchments and drainage lines for input into a customised rainfall-runof modelling program. I want it based on subwatersheds that I delineate. Once I have subwatersheds, I want to be able to…(Show moreShow less)
Stream Definition- empty output I'm sharing this link here because I'm confused about where questions like this should go. I finally figured out that there is an Arc Hydro "group" and an Arc Hydro "space" and I don't know what the purpose of each one is. Thanks,
Hi Lorna, "Spaces" are GeoNet admin created sub-areas of GeoNet for the purpose of asking questions or having discussions on a particular topic. "Groups" are GeoNet users created areas that can be public or private also generally for questions or discussion. Posting in the appropriate space with a general question is probably the better…
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)
Hello, Today I have downloaded and redownloaded hydro tools for arcdesktop 10.4.1, but I cannot get it to work. Every time I click anything in the toolbar, it crashes arc. I worked around that by accessing the hydro tools in the tool box, but am stuck again. I am trying to recondition a raster, but I am getting the same Hresult COM error that I…(Show moreShow less)
Hi All, I'm currently trying to run through the ArcHydro Tools 2.0 Tutorial with the provided San Marcos data. I'm running ArcMap 10.2 and using the 10.2 x64 version of the ArcHydro Toolset; the OS is 64-bit Windows 7. I've successfully created a Flow Direction Grid using the FilSink DEM produced during the course of the tutorial. In order to…(Show moreShow less)
I had this problem too. I was getting the same error message when running the tool from the toolbar, and a slightly different one when running it from toolbox (although I only did that once... I may have gotten a different message if I'd tried multiple times). I did 2 things to fix it. I removed a dash from the path name, and I deleted all of the…
Hi everyone, I have a problem with the function create drainage line with arc hydro 2.0. I run it under ArcGIS 10.0 SP 5 with Version with the latest Version of Arc Hydro. Unfortunately I always have an error while executing. the error message is attached. I am thankful for every idea!
I am having this exact problem with both this tool and the create sink structures tool. I believe that what Jakub Sisak suggested is the cause. I have the Basic license only. I haven't upgraded my license to test this, but it seems like the likely issue. I wish the error messages could be updated to reflect this, I spent a long time searching for…
I've upgraded to ArcGis 10.5 and have tried to install the relevant ArcHydro version (obtained from /archydro/archydro/Setup/10.5/), but the installation won't progress beyond the 'PreInstall' stage. The message that pops up says 'The ApFramework could not find the Arcgis 10.3 for Desktop install directory C:\ ARCGISHOME\'. Can anyone assist?
