Hydroflow with Civil 3D

[drainchick]

I am using Hydroflow to model an existing subdivision. It has three detention ponds. In reading the manual, it stated that only two ponds can be interconnected at once. I assume that I can connect three ponds in series. Is this correct?

Also is the pipe between the ponds considered a reach???

The existing outfall is open to the atmosphere. I do not see a separate icon for the outfall.

Thank you very much,

yes, you can connect 3 ponds in series. just have the outfall hydrograph from one pond routed through your next pond, etc etc.

you can model the outfall pipe (Culv/Orifice"A") with a long length or as a reach but be careful not to do both. I would do both scenarios separately and use your best judgment as to which is more accurate.
