Thanks! Each branch has it's own capacity/bandwidth taking a part of water from the cell. At the end of turn you can see how much water remains in the cell. As long as there is some, each new branch would utilize it. If there is no water in cell at the end of turn, new branches would have no impact at this cell. At this moment (end of simulation) you also can select each branch and look at it impact during last turn in the side panel.
