Hi,
I am trying to create cathcment (e.g. loch) from dem. Some time initial loch out-let (maximum flow accumulation point) does not provide expected catchment shape. At this point I am trying to move the out-let point one cell further down (each time) by using expand tool. Infact I know how to declare it (initial out-let point) as list and put 1,2,3..cell to expand. However, is there any way that model itself will increase the cell number automatically untill a certain condition is meet rather than manually input it. For example, in one loch only two cell expansion gave the desired catchment while in another loch it required 38 cells!
Thank you.
