I am trying to delineate watersheds automatically using Arcgis/Arc Hydro. I got the drainage area contribution of stream segment (part of stream) as shown in figure stream. The corresponding drainage area as shown in figure area. But I am looking for drainage areas/catchment areas as shown in figure Water Shed. In watershed figure , at any point on the stream, it calculates drainage area by considering entire upstream length of the stream. Suppose, if you choose point "8", its catchment/drainage area covers the area of points "9" and "10". Similarly for point "5" covers all points upstream of stream. I want to get similar automatic watershed delineations. Please guide me to the software/method to get the result as shown in figure watershed for my entire stream network of an area.
