The NHD Watershed Tool Page was removed from public access for a while until we received feedback that, although some of it is dated in terms of tool usage, much of it is still very relevant in terms of processing steps. A watershed is an area of land that captures water, which eventually flows through a single point or outlet such as rivers, reservoirs, and the ocean. I am having real problems with the watershed tool producing a catchment of only a few pixels when i know that the flow direction is downhill (4) from the pour point A watershed is an upslope area that contributes water flow as concentrated drainage. There are different file names in different formats on CD. When the tool completes, you should have Tool layer for the Create Polygon Watershed tool. The Watershed Tools assist with Hydrologic Unit Delineation and Attribution in the Arc coverage format. 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 Trace Downstream tool is just as easy to use, and is based upon the same datasets as Create Watersheds. Watersheds can be delineated from a DEM by computing the flow direction and using it in the Watershed tool. The Watershed tool is advantageous when analyzing familiar areas where the locations of the pour points are known. Set Data Source Resolution to 30 meter. Right-click the tool layer and click Open. You identify a location you are interested in finding a watershed for, and whether you wish to snap the location to the nearest stream. I have a CD of GIS files of a city and intend to work on watershed management. When specifying the input pour point locations as feature data, the default field will be the first available valid field. The Create Watersheds tool is used to determine how much habitat is made accessible with the construction of a fishway at a chosen dam. A watershed is the upslope area that contributes flow to a common outlet as concentrated drainage. For each input point a watershed feature will be returned. The Watershed and Trace Downstream tools no longer charge credits and are FREE to use with an ArcGIS Online for Organizations Account.. Watershed and Trace Downstream are online tools that create upstream drainage areas or downstream flow paths in seconds at points around the world. Report Abuse . It's a bit of an involved workflow but it is important that each step be completed properly otherwise you're very unlikely to get a satisfactory watershed at the end. Output watershed features are the complete upstream area that contributes flow. Legal . Watershed tool in arcgis online.

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. All Communities. 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. This page documents these steps as well as any other training documents available as of 2013. To determine the contributing area, a raster representing the direction of flow must first be created with the Flow Direction tool. The value of each watershed will be taken from the value of the source in the input raster or feature pour point data. For the last 3 years, it has consistently run, taking about 90 seconds each time - I've used it thousands of times. It is the lowest point along the boundary of a watershed.
