Watershed Delineation with ArcGIS 10.2.x Watersheds, also known as basins or catchments, are physically delineated by the area upstream from a specified outlet point. The tool works from downstream to upstream, thus, when two or more segments along a stream are selected, the lower selected segment-watershed will not overwrite the upper, but rather it will select the drainage area between the two. These include tools as watershed delineation, flow accumulation, and flow length. To use this tool, you require the drainage direction raster and the coordinates of the closing point: NOTE: The coordinates must be expressed in the same units as the map. Before proceeding with watershed delineation or any other kind of hydrological analysis, your data sets need to be in a projected coordinate system in which the horizontal units of the xy coordinates are the same as the vertical elevation units of your DEM. This component is an automated sequence of steps by which the user can interactively activate some options to improve the results and define the desired configuration. Polygons are named and can be retrieved at a later date (5).
