Watershed Delineation with ArcGIS x. Watersheds, also known as basins or catchments, are physically delineated by the area upstream from a specified outlet point. Watersheds can be delineated manually using paper maps, or digitally in a GIS environment. Jan 13,  · Delineating watersheds. A subwatershed is simply part of a hierarchy, implying that a given watershed is part of a larger watershed. Watersheds can be delineated from a DEM by computing the flow direction and using it in the Watershed function. The Watershed function uses a raster of flow direction to determine contributing area. How to Delineate Watersheds in ArcGIS for Desktop | MD DoIT GIO Page 10 of 13 Ensure your snap pour point cell is directly on top of a cell of high accumulation: Our final process is delineating the watershed. Up to this point we have generated the necessary datasets for processing the watershed. It is recommended to not delete any of.
