Watershed Delineation Concepts Instructional Videos. Use of the tool is shown in Figure 1. Besides watershed delineation, this extension will have tools for topographic characteristic extraction, hydrologic parameter definition, and model input file generation, similar to CRWR-PrePro (Olivera and Maidment, 1999). by MitchellWinieck i. d. Verify the path name for the 'Output raster'. Do an online watershed delineation and then extract the data for that watershed to perform a more detailed analysis. Run the Watershed tool.

Although similar tools are available, such as ESRI’s ArcHydro framework (Maidment, 2002) and the Multi-Watershed Delineation Tool (Chinnayakanahalli, K. et al., 2006), these tools do not specifically allow overlapping, upstream catchment area delineation. These include tools as watershed delineation, flow accumulation, and flow length. Watershed Delineation. Rough pixelated edges along the polygon can be smoothed (2). A point is selected on the centerline network. DEM size, or the size of the resulting watershed. These videos were created by Dr. Jane Frankenberger and Dr. Fariborz Daneshvar of Purdue University to provide an on-demand introduction to learning SWAT. The watersheds for points, segments, or polygons can be delineated either interactively or in the batch mode where the data of interest are provided to the application in the form of shape files.
