topic Catchment generation/model iteration in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/catchment-generation-model-iteration/m-p/73672#M2596 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>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!</SPAN><BR /><BR /><SPAN>Thank you.</SPAN><BR /><SPAN>Rajib</SPAN></BODY></HTML> Mon, 16 Aug 2010 09:58:35 GMT MohammedHaq 2010-08-16T09:58:35Z Catchment generation/model iteration https://community.esri.com/t5/geoprocessing-questions/catchment-generation-model-iteration/m-p/73672#M2596 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I am trying to create cathcment (e.g. loch) from dem.
