  1. I just had another idea! How do the culverts work with the stream arcs? If I specify a hydraulic structure, then does GSSHA just add that structure at that node or does it apply that to the stream arc. For example, if I added in a 100 foot long culvert at a node, would GSSHA interpret that as adding an additional 100 feet of channel between the stream arcs on either side of the node or does it interpret that as the first 100 feet of the stream arc is simulated as the culvert instead of being simulated as the open channel? Maybe I can sort of stack culverts with the storm drain outlets so
  2. Hi Chris, Thanks for your reply! I think using the culvert option in GSSHA will work for areas where the open channel flows in a closed conduit and doesn't receive any additional from from any lateral storm sewer connections. However, there are still a couple of spots in my watershed where I have an open channel that flows into a pipe but then several pipes converge before discharging back into an open channel. So, I think in these situations the culvert option won't work because the flow volume is changing. I tried out a few ideas of how I could simulate this: I found a repor
  3. Hello! I'm constructing a GSSHA model of an urban watershed and in my watershed there are some open channels that flow into closed conduits (pipes/storm sewer) and then flow back into open channels. I've successfully run some GSSHA models including a GSSHA Storm Drain SUPERLINK coverage and I can get the storm sewer to discharge to a stream arc or the overland grid. However, after running the model and looking through the user manuals, it appears that the SUPERLINK storm sewers only receive water from the overland grid and not from the stream arcs. Is there any way to set a stream ar
