My most recent discovery is more generally related to geoprocessing and is not specific to Arc Hydro. However, since Arc Hydro is heavy on geoprocessing, I wanted to post this here. My latest Arc Hydro project had ArcMap freezing up when saving and at other times. I'd have to wait forever or, out of impatient frustration, I would "X" out and/or cancel it using Task Manager. Then I heard about something in the geoprocessing options that seems to have put and end to that! Under the menu Geoprocessing chose Geoprocessing Options. On the Geoprocessing Options window change the "Keep results younger than:" to something low. I have mine set a 1 day. It might have been set a 2 months. This reduces the amount of results that are shown on the Results tab you get under the Geoprocessing>Results menu item.  This seems to make saving much, much faster and I haven't had it crash yet. Hope this tip helps! Mark ... View more

Jomar, I don't recall running into that error when generating an HMS project using GeoHMS. However, I have not repeatedly used GeoHMS to generate a lot of projects. I'd say I've used it less than a dozen times. Also, it has been a long time since I have used GeoHMS. The error "System.Runtime.IteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component." is a very generic error message. The HRESULT is a "tag" for a type of error code to distinguish certain error codes from other error codes. (HRESULT - Wikipedia ). I am not a systems administrator. I don't have training on database structure. I'm no expert on discerning network or database errors, let along Arc Map errors. Having said that, I have gotten around this mysterious type of error by simplifying the names of layers, and running the Arc Hydro project on my local drive and on a network server. When I started making my project names without spaces and as short as possible, frustrating and mysterious errors all basically vanished. When I started putting my .mxd (and therefore my Arc Hydro project directories on my local PC (C: drive)), the processing speed increased dramatically.  If I do run into the errors, I will save everything, close ArcMap, and restart my PC. For some reason the errors will go away when I do that. I've wondered if the "undo" list gets too long and causes things to freeze up. Just my own "superstition". So, if you haven't yet, you should put the .mxd and GeoHMS project on your local PC and make sure the file path names are short and have not spaces. I also used Model Builder to "program" the steps needed to process the data. This helps me if I have to restart the process over and over to get past errors. it also documents the process. Most, if not all, Arc Hydro and GeoHMS commands can be run using the Toolbox tools and these can be "programed" in Model Builder. Hope this helps. Mark ... View more

I uninstalled ArcHydro and installed the version from 6/2/2016 4:43 PM <dir> 10.4.0.3. Things appear to be running OK now. This looks like the latest version even though the data on the directory is not the latest. I also ran the python version for the Terrain PreProcessing Workflows/Dendritic version and it ran without a hitch. ... View more

Christine, Which version should I download for ArcMap 10.4.1.5686? 4/13/2016 8:58 AM <dir> 10.4.0.1 7/13/2016 10:33 AM <dir> 10.4.0.12 6/2/2016 4:43 PM <dir> 10.4.0.3 Mark ... View more

I discovered this also after having lots of problems getting Arc Hydro (supposedly 10.4) to work without crashing. It must have crashed a dozen or more times yesterday (10/4/2016). I still did not get done what I wanted to get done. Skeptical it'll work right today. Considering simply using Spatial Analyst tools to get this problem done. Has anyone heard from ESRI if the v10.2 in the toolbar is an edit they overlooked? Is it actually for v10.4?  Yesterday I turned off the toolbar, closed ArcMap, rebooted, etc. before re-installing v10.4.  After all that, I still had problems. Toolbar help says what Dan pointed out:   "Welcome to Arc Hydro for ArcGIS 10.2 (version 10.2, March 30 2015)" I'm running v10.4.1 and installed ArcHydroTools_x64.msi. from:  yellow.esri.com - /archydro/archydro/Setup/10.4/10.4.0.12/ArcHydroTools10.4x64/  7/13/2016 10:31 AM     63235584 ArcHydroTools_x64.msi ...

My projects are not so large. I don't know if the large size of the tables causes problems. I have heard, and do practice normally, putting data in geodatabases to reduce the instability issues that can come when using simple shape files. ... View more

I just today had to upgrade to 10.4. I also downloaded the 10.4 Arc Hydro install and am about to install it. If I notice the same problems I'll let you know. ... View more

I've never worked with deranged basins, or "create sink structures", so I'm not sure I'd be of any help. Sorry. ... View more

My first thought is to make sure your processing extents include your area and that your datasets/feature classes all have projections and that they are all the same. Slightly different note ...  I have recently built my own DEM Reconditioning Model Builder model. I've saved it in a toolbox to my desktop and am attaching it. I've also saved it to Python and attached that. I don't know if this site works for sharing a file like this. Let me know if it does. The attached image shows it graphically. The reason I built it was because the Arc Hydro DEM Reconditioning tools would crash or something. If you can download the toolbox you should be able to put it in your project directory like any other file. Then in ArcMap you can open the toolbox and edit the model. You will need to rename most of the files since the path is defaulted to the path I am using. This model seems to do the same thing the Arc Hydro tool does and I don't get errors. It doesn't do it as "nicely" as Arc Hydro in that it does not out the output in a "default" folder named after the .mxd or the the data frame. I have it go all the way to fdr and I have it calculate a "minus" raster. I then symbolize the minus raster in a light blue to dark blue color ramp and set the zero values to no color (null). This lets me see the location and magnitude of the fills and I can check to see if I need to add to my agree stream layer. I have it calculate the fdr raster so I can use the flowpath tool to poke around and make sure things are flowing where I think they should. This is a helpful procedure in urban areas. I tend to iterate through these steps quit a bit before I move on. If you run the Arc Hydro tools first, certain folders will be created. You can create you own with the geodatabase in your project folder with the same name as the .mxd and the dataset with the same name as the data frame. The rasters go in a folder with the same name as the data frame. After this, I definitely use the Arc Hydro tools for the rest of the process. I haven't gotten into arcpy just yet. Lastly, I've attached a document I made for myself and future staff who may use Arc Hydro. This has the basic tips on how to setup your Arc Map to avoid errors. Best, Mark ... View more

The traces and points generated with the flow path tracing tool are simple are graphics. Select them with the "arrow" tool. Under Edit you can choose "Select all Elements" to select them all. Press delete or click the "X" to delete them.  Be carefull with this in layout view! Since they are graphics, you can convert them to a shapefile using the "Drawing" tool bar menu tool "Convert Graphics to Features". ... View more

I downloaded your data. I projected the streams layer to the same coordinate system a you dem and changed the project on the data frame to that same projection. I ran the dem reconditioning using the dem and the reprojected streams dataset and it ran without error. Mark ... View more

Your raster's coordinate system is:                USA_Contiguous_Albers_Equal_Area_Conic_USGS_version, WKID: 102039 Authority: ESRI Your polyline layer coordinate system is:                GCS_North_American_1983, WKID: 4269 Authority: EPSG Your first step is to choose the coordinate system for your project and reproject the data to the same coordinate system.

Next thing to check: Make sure the projections are the same on all datasets. If the projection is different or not defined, you can get strange results. ... View more
