GIS Tutorial for Watershed Delineation CEE 577, Spring 2013 Liz Isenstein Objective: Learn how to delineate a watershed for a point of interest using a digital elevation model (DEM) and the ArcGIS Spatial Analyst Extension Background: A digital elevation model (DEM) is a regularly spaced grid of numbers representing elevation – Delineating Watersheds from a Digital Elevation Model (DEM) Updated January 17, 2012 ... • Why use the Basin tool instead of the Watershed tool? When the threshold is used to define a watershed, the pour points for the watershed will be the junctions of a stream network derived from flow accumulation. The points can be loaded through the input drop-down menu or created using the Draw tool. The value of each watershed will be taken from the value of the source in the input raster or feature pour point data. I am using ArcGIS Desktop 10.2. ArcGIS. Section 3 - Delineating a Watershed – Overview of Steps ArcGIS can delineate the total area flowing into a given outlet, also called a pour point, based on a digital elevation model. It is easy for the delineation to be miscalculated and you may need to throughout the watershed delineation process. However, this method prevents the user from selecting or viewing pour points, which is one of the most crucial steps in watershed delineation.
