Arc Hydro Tools 10.3 Download

I am trying to run a function from Arc Hydro tools in ArcMap 10.1; Sink evaluation. But before it can finish it returns an error message, that, frankly, I don't understand at all. It goes System.runtime.interopservices.comexception (0x80004005): error hresult e_fail .
Can anyone help me solve this? I have tried all I can think of. Run the function from the toolbox instead of dropdown menus, shorten paths, restart ArcMap, reinstall AHT, open new map documents, restart my computer, wait till next day and see if it automagically have fixed itself...
I think I have narrowed it down a bit, still not clear what's wrong though. Sink evaluation uses a series of functions in Arcmap, of which one is Zonal statistics as table. That's the one it gets stuck on. The input raster somehow does not exist, path unknown. I guess this is some intermediary raster.
After consulting the Arc Hydro team, I got the advice not to use grids stored in a gdb (which I didn't). I have also tried to change target locations, thanks to @G.Oxsen. Unfortunately neither of those solved the issue. According to the Arc Hydro team, GPL0 that I asked about earlier is an in-memory grid, so probably no problem there.
By reducing the number of sinks in need of processing I managed to get Sink evaluation running. Having the files not stored in a gdb seem to help as well, as mentioned earlier, and using integer grids. Changing the "Maximum number of unique values to render" in ArcMap Options (Customize menu), tab Raster --> Raster dataset is another tip that I got (from the Arc Hydro Team). Restarting ArcMap after running every one or two functions also helps keeping things stable.
I had a similar problem with archydro tools in ArcGIS 10.0 Try going to the archydro tool bar and go to ApUtilities>Set Target Location. Go into each section in that list and edit the Raster Data target locations. Make sure the location is targeted to a standard folder and not a .gdb or .mdb (in the selection window make sure the "Show of type:" field is set to "Shapefile/Raster Workspace" and not "Personal/File Geodatabase"). You may be able to accomplish the same goal through the environment options (Geoprocessing drop down menu ) by changing the workspace environment to a regular folder and not a .gdb or .mdb,but I would not mess with the workspace environment unless I had to. Changing the workspace environment will affect all of the processes not just the raster environment for archydro tools. Let me know if this helps.
To fix this I implemented the steps mentioned above and I did not change the output destinations of any files on any operation starting from (Preprocessing) so by default it stored them in a folder called (Layers). The error didn't happen again due to me "going with the flow".
Now if you're interested in what I was doing wrong, I deliberately changed the output destination to the file geodatabase I was working on (I did that as a work-around a previous error, little did I know I was making things worse). The "RawDEM" file was gone and couldn't be selected or found so I had to use the original DEM I had-That was a sure sign that something was wrong-. It was a huge mess. Anyways the HRESULT error is no more.
I had this HRESULT error once. It was happening because I used to change the output destination manually each time ( starting from the operations inside the Preprocessing menu ) instead of letting the program decide by default. So simply go with the suggestions mentioned above - especially the ones about vector and raster files output destinations - and just go with the flow and don't change anything.
The database is the main problem. If you want to solve this problem create a new geodatabase or copy the original geodatabase from your document folder to your currently working on project folder. Then set the copied geodatabase as default geodatabase and start sinking.notice:
I am testing some python scripts created originally in ArcGIS 10.3.1/10.5.1 which utilize the ArcHydroTools module. I have installed the latest Arc Hydro package in ArcGIS Pro, but it still doesn't recognize this module. I get the following error when trying to import the module:
Thanks for the tip for adding the toolbox, but I am still getting the same error. Either the python functionality isn't there yet or they changed how to access it.. which would be unfortunate, since many of the standard tools are accessed exactly the same way under both platforms (with a few notable exceptions - but they're usually well explained). The same should hold true for Arc Hydro.
Since PRO is a new beast and requires an Anaconda setup and distribution of python. I would not assume that an installation as before would remotely work since it would have to have been installed within the PRO/Anaconda package distribution.

Are you looking for the most recent version of the Arc Hydro tools (or past versions)? If so, look no further. Follow this link to our Arc Hydro GeoNet Space. Or follow this link which takes to you the direct downloads.
Please can anyone assist me knowing how access Arc Hydro tools in my ArcGIS pro account. I recently downloaded it and would like to use it for delineating a watershed. Also do I need spatial analyst license enabled to utilize the Arc Hydro tools?
Hydro clamping chucks can be a great option for CNC machines equipped with HSK tool interface. Precision balanced to 25,000 rpm, the tempered and ground tool holder will provide higher clamping precision than a standard collet and nut are able to, since it grips the tool shank absolutely concentrically over the full length of the shaft.
HSK hydro tool holders offer the same high precision clamping tolerance of heat shrink tool holders, without the additional investment in a heat induction unit. Precision balanced to 25,000 rpm, the tempered and ground tool holder provides higher clamping precision than a standard collet chuck (.003mm versus .006-010mm of standard chucks).

The following tools are provided to assist in the use of USGS Hydrography Datasets. Any problems encountered when using these tools should be reported to National Hydrography Support.
Hydrographic addressing, also referred to as linear referencing, indexing, or linking, is a means to align data features relevant to the stream network to be coincident with National Hydrography Dataset (NHD) features. Addressing data to the NHD enables it to be used as a base for analysis and knowledge. Any kind of hydro-related observations can be addressed to the NHD such as observations relating to hydrology, geomorphology, water quality, biology, regulations, etc.
The Hydrography Addressing Tool, or HydroAdd, is a web-based tool that allows users to address data to the National Hydrography Dataset (NHD). The addressing process also spatially joins some NHD flowline attributes to data features being addressed. Because HydroAdd is a web-based tool, multiple users can collaborate on shared projects.
The NHD Utilities is a suite of stand-alone software functions that were designed to help users manipulate National Hydrography Dataset (NHD) data. These tools are not necessarily part of the maintenance/update process for NHD, but are very useful to those performing different sorts of data manipulation and analysis with NHD data. This suite of tools includes; Network Builder, Build Flow, M-Value Utility, Geodatabase to Shapefile (GDB2Shp), Shapefile to Geodatabase (Shp2GDB), Subset by Polygon, and NHD Merge. The USGS NGTOC maintains on one version of these NHD Utilities usually for the current version of the ESRI ArcGIS application.
The WRAP Hydro Tools contain tools for for delineating watersheds and accumulating attributes from watersheds to junctions on the stream network. It was written to support the processing of GIS data for use in the WRAP simulation model.
Update: 16 Apr 2004
Fixed error when using Advanced Tools-->Delineate Watersheds to delineate watersheds for source features with a source attribute whose field name is longer than 10 characters, or whose ObjectID field is longer than 10 characters (i.e. ObjectID_12). NOTE: This bug has only been fixed for the ArcGIS 8 version of the tools
This DLL contains two tools to help in visualization a set of features and their related features. The Copy Legend tool copies the legend colors from source features to related features, so that associated features are rendered in the same color. The Zoom and Flash tool zooms to each feature, flashes its geometry, and then flashes the geometry of related features.
For those new to programming in ArcObjects, this module provides a simple example of how to gather inputs from ArcMap, perform an edit operation, and store the results in a feature class. The sample code is fully commented with explanations about each step in the procedure. To use the module, unzip modLesson1.bas from the zip file. Then start ArcMap and add the module to ArcMap's VBA environment. As you browse the module, you'll notice one public subroutine that you can call as a macro from ArcMap.
NWIS is the USGS National Water Information System. The NWIS tool reads USGS gage ID's from gage stations on your map and retrieves stream discharge information from NWIS for a specified period of record. The tool then processes the data and builds a time series table to store the data.
