This is the table defining the time series variables. You can find one as an example in the ArcHydroSchema.mdb template geodatabase located in the ArcHydro\bin folder. Christine Dartiguenave Esri Water Resources Team ... View more

Point Delineation is a 2-step process: 1. Perform a local delineation within the extent of the catchment located under the point. 2. If point is located on a stream grid, find AdjointCatchment feature associated to local Catchment through GridID/GridID relationship and merge with local delineation. If the GridIDs are out of synch between the Catchment and the AdjointCatchment features, you will end up with a delineation limited to the extent of the local catchment (and missing the upstream adjoint catchment).

Your output cannot be a shape file (Longestflowpath1.shp). It needs to be feature class stored in a geodatabase. Christine Dartiguenave Esri Water Resources Team ... View more

It looks like something went wrong and the tool tried to write a temp raster in a system location (c:\windows\system32\ras02 ) instead of the temp location. What version of ArcGIS/Arc Hydro are you using? Christine Dartiguenave Esri Water Resources Team ... View more

It looks like the tool is not seing the correct definition for the input from the XML and reverts to the default (point) type. My clue is that the name in the UI should be: "Sink Watershed Grid" instead of "SinkWatershedGrid". Can you try in a new map, save it and click the tool right away to see whether the UI shows correctly with the space in the name? Christine Dartiguenave Esri Water Resources Team ... View more

ArcGIS Desktop works in the 32bit environment whether your computer is 32 or 64bit. If you have installed the Desktop Background Geoprocessing (64-bit) as well, then the geoprocessing tools in ArcGIS desktop will run in the 64bit environment. If you have installed ArcGIS server and published some services using the Arc Hydro tools, these services will also run in the 64bit environment. So if you have either background (64 bit) or server installed and plan to use Arc Hydro in background/server mode, you need to run the 64 bit install so that the Arc Hydro files are correctly registered with both 32bit (standard desktop) and background 64-bit/server. If you do not care about these 2 features, you can install either 32 or 64 bit on a 64-bit computer. The 64 bit installs additional files on the 64 bit program files location and perform additional registration (if server or background 64-bit are found).

FYI - There is a new tool in Arc Hydro, Thin Cross-Section, available in the Arc Hydro Tools toolbox>H&H Modeling>Utility toolset that allows filtering the vertices in cross sections using either a fixed number of vertices or a fraction of the original number of vertices.

The input depends on the operations you performed on the DEM. With that tool, you adjust the flow direction grid within the lakes so that the water flows toward the closest stream feature within the lakes. You may or not have sinks in your dem you want to preserve (or fill). So the input is your flow direction grid created and adjusted, if needed, in sinks and/or streams.

Have you tried to construct the mosaic dataset boundary using Build Boundary and then use the Boundary Polygon to clip? Christine Dartiguenave Esri Water Resouces Team ... View more

You need to run both functions. DEM Reconditioning will burn in the streams into the DEM. You can then fill the resulting DEM (as needed) before created the associated Flow Direction grid. Then running Adjust Flow Direction in Stream will ensure that once the water reaches a stream it flows downsteam along the digitized stream direction and enforces the flow splits (if any).
