How do I design a channel run to flow into another run?

The ‘Add Point Inflows’ tab accessed through the Catchment Information panel will allow additional flows to be added into a channel run.

First select “ADD INFLOW” and then use the scroll down bar next to the “Point Inflow:” box to select the run to be added into the current selection, or add a point inflow if a fixed flow is known, this will input the flow rate from the chosen channel run.
