New to Hydraflow, using 2011... I notice when exporting a storm network from C3D to Hydraflow that Null Structures (which have no "rim elevation" parameter) use, more or less, top of pipe as ground information. Is there a workaround for that? Is it even something to fret about?
I have a similar problem with SSA, however, the only way around this issue was to treat each null structure as a manhole junction. I made sure there were no sub basins connected to them, but other than that I could not think of another way around it.
