Note: The Watershed tool delineates the upslope contributing area with flow direction input created from a DEM surface. ; For Input raster, select the raster output from Step 6.. Sublayers appear if the tool outputs exist at the time you create the tool layer. Using DEM data-sets watershed delineation is processed for particular region. Once you have created flow directions and stream networks, you can use other hydrologic analysis tools to specify flow lengths, stream links, stream orders and stream features. To determine the contributing area, a raster representing the direction of flow must first be created with the Flow Direction tool. When the pour point is a point feature dataset, the values will come from the specified field. When the pour point is a raster dataset, the cell values will be used. Finally, you can use the Watershed tool to extract the watershed polygon(s) for the pour point(s).

Question asked by jcollin on Feb 3, 2016 Latest reply on Feb 3, 2016 by jcollin. A watershed is an area where water that falls or flows across the surface of the land drains into a stream or river, and eventually flows through a single point or outlet. The Automated Geospatial Watershed Assessment (AGWA) tool is a geographic information systems (GIS) interface designed to help manage and analyze watershed water quantity and quality. Watersheds can be delineated from a DEM by computing the flow direction and using it in the Watershed tool. To determine the contributing area, a raster representing the direction of flow must first be created with the Flow Direction tool. The data that provides input for the models is in c:\arcgis\ArcTutor\GP Service Examples\Watershed. The tool allows for control over the pour point information. There are different file names in different formats on CD. When specifying the input pour point locations as feature data, the default field will be the first available valid field. A watershed is the upslope area that contributes flow to a common outlet as concentrated drainage. 数年前、私はWatershed Delineationプロジェクトに取り組んでおり、D8メソッドを使用するArcGISが原因でいくつかの問題に直面していました。2つの主な問題は D8は単一方向フローのみを許可します。水は、1つのセルから一方向にのみ Create Watersheds performs a complete workflow using similar capabilities to the Hydrology toolset.
