StreamOrder uses flow direction as input, i.e. flow can only go one way so braided network are not supported. If you have a braided network you can use the Assign River Order tool from the Arc Hydro toolbox or Arc Hydro Python toolbox. It is located in the Attribute tool toolset. This tool takes as optional input a flow split table that allows the tool to handle braids. Coming in with your own streams feature class you will need to run the following tools: · Assign HydroID · Generate From/To Node for Lines (store connectivity) · Find NextDownstream Line (to create the flow split table and NextDownIDs) · Assign River Order. Also the field OmitUp (0/1) if present is used to reset the order to 1 in a secondary braid segment. Christine Dartiguenave Esri Water Resources Team ... View more

In case you have to use the mft site... note the password change as of 8/26/2016 to ADSRiver.2016b Christine ... View more

This is correct. This password will expire in August and be replaced with ADSRiver.2016b at that time. Note that we are trying to move away from the mft site. You should go to http://downloads.esri.com/archydro to get the updates instead. Christine ... View more

Ismael, It would make sense in my case because I am dealing with a few hundred values only and having a domain helps ensure the data integrity when the user edits/qcs the layer. So having the option to create a domain would be great in my case. Christine ... View more

C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcToolbox\Toolboxes is the location for the System toolboxes - the main Arc Hydro toolboxes are located there. C:\Program Files (x86)\Esri\WaterUtils\ArcHydro\ArcToolbox\Toolboxes is for the more project specific toolboxes developed as part of projects and integrated with Arc Hydro.

The spatial reference is now read from the auxiliary file (*.aux.xml) associated to the raster. This file contains information on the raster that cannot be stored in the raster itself (e.g. spatial reference in the SRS section). The old projection file is overwritten based on the content of the auxiliary file – this is why ArcMap will not recognize the changes to the projection file. You can modify the spatial reference properties and set the z unit in the Z Coordinate System tab in the Spatial Reference Properties window. You can select an existing Z Coordinate System or create a custom one by right-clicking and existing one and selecting Copy and Modify. Christine Dartiguenave Esri Water Resources Team ... View more

Basically you need to add "import ArcHydroTools" a the beginning of your script. Then you can access the tools using ArcHydroTools.DrainageLineProcessing() You can test it in the Python window in ArcMap. >>> import ArcHydroTools >>> ArcHydroTools.DrainageLineProcessing( Christine Dartiguenave Esri Water Resources Team ...
