I am using GeoPak Drainage to model a fairly typical closed urban drainage system. My section of this model is the lat part of a larger drainage system - the upstream section is being modeled by another consultant. That consultant has provided me with a total drainage area, "C", Time of Concentration and invert up to where I pick up the flows.
I would like to bring this into the manhole where they join as a computed discharge, but if I connect an inlet, I get the warning that the inlet cannot accept the flow and it needs to bypass to another structure. I don't want to input just the flow, becuase I want the flow to be able to vary with the ToC as it continues downstream.
Is there a way to force the inlet to accept the entire flow, or another way to add that flow without an inlet and still make it variable?
Thanks,

Hi Robert,
there is a field on the Node dialog specifically for this purpose.
You can add the Base Flow (Q) or Base Area (your choice which data you want to use) and it will be added to the pipe system BUT not to the surface inflow of this node. If you decide to add the area, you will need to create an additional drainage area (that would be the total upstream region that will be added from this location down) and then select this area.
Go to the appropriate Edit>Node dialog.
Look at the bottom toggle on the Discharge Options panel. This is where you add the Q or the area.
