Things have slightly changed and we are in the process of documenting the changes... Initially we were using Flow Direction/Fill Sinks. So if a stream was not connected to another stream, to a HydroJunction (i..e, Pipe Inlet or real Sink Point)  or exiting the DEM, then the Fill operation would fill the enforced stream back up and the flow direction would not honor the burned in streams. With the new Derive Continuous Flow tool in Spatial Analyst (Flow  Direction and Accumulation Using CF in the Arc Hydro toolbox), the  Fill Sinks step is not needed anymore and the streams will never be filled. So you can now connect the streams to an outlet if you wish to do so. The process will create overland connector from the outlet using the flow direction. Note that it is possible to end up with a sink in the flow direction at the end of the isolated streams since we adjust the flow direction in the direction of the flow under the streams.  So it may be a good idea to trace from the end of the isolated stream to see whether the path is correct (sink or not). If the ends of the stream is a real sink, add a HydroJunction to indicate that. If the trace ends at the stream but should continue, you can either: - trace/digitize that path and add it to the input streaminit and reprocess.  - do not burn those isolated streams so that the sink is not introduced Christine ...

Currently we have a tool called Assign River Order in Arc Hydro that allows assigning Stream Order to features but it works on a single feature class. So you would need to merge the streams and pipes into one layer and make sure you only have one segment between confluences to be able to use it. Here is an example of the stormwater process. Pipes are in green and in this example streaminit is the initial stream layer that was burnt in through reconditioning since the input DEM was not "perfect". The inlet to the pipe is a sink. When tracing from the surface, you can see that the flow in yellow ends in the sink point (HydroJunction). When we do a delineation we trace through the network of both pipes and streams to add upstream contribution. We do not burn in pipes since they do not impact the surface flow. Christine ...

Is there a reason why you want to burn in the closed pipes? We usually only define the inlets to pipes as sink point with an associated sink watershed so that they attract the water and then use the pipe in the network to transport the water in the direction of the digitized line. If your input DEM is great, you may not need to burn in the streams either, but if it is not you may need to. You can use the Stormwater Processing tool after defining the inlets and associated sink watersheds, streams, pipes and outlets (created using Create Pipe Outlet). Then run Create Stormwater Network and check the resulting trace network to view the connectivity.   Christine     ... View more

Arc Hydro uses generic ArcGIS Pro tools. For example, the stormwater processing tool script that you can check as an example uses the Derive Continuous Flow tool. So, you can intermingle any tool you need. Christine ... View more

Arc Hydro contains some tools that handle stormwater infrastructure. Basically data are considered as inlet, outlet, open channel (streams), closed pipes (pipes, culvert). The water enters a closed pipe through an inlet (sink) and leaves through outlets. Arc Hydro creates connectors for the outlets by tracing from the end of the pipes. You can find more information on the process in the following documents: https://www.esri.com/content/dam/esrisites/en-us/media/powerpoints/arc-hydro-for-stormwater-overview.pdf https://www.esri.com/content/dam/esrisites/en-us/media/technical-papers/arc-hydro-stormwater-processing-pro.pdf https://mediaspace.esri.com/media/t/1_dmcvd1i9/244549852 Note that these documents are being updated to reflect the latest changes in the tools with the use of the continuous flow method for flow direction and the addition of stream outlets to add the ability to trace from the end of open channel ditches.

Is there a chance you get upgrade to a later version of Pro? There have been some changes in the underlying functions and things are working a little differently in 3.0 vs. 3.1 and later. Also note that we have a Pro version of the document you can use: https://downloads.esri.com/archydro/ArcHydro/Doc/Arc%20Hydro%20-%20Stormwater%20Processing%20-%20Pro.pdf Christine ... View more

I just tested the setup and it works correctly. It looks like you may have another older version of apwrutils.py on your computer that is missing the function. Can you do a search and delete it? You will need to restart ArcGIS Pro as well. Christine ... View more
