Impact/Purpose:
The Automated Geospatial Watershed Assessment (AGWA) tool uses widely available standardized spatial datasets that are readily obtained via the Internet. The data are used to develop input parameter files for two watershed runoff and erosion models: KINEROS2 and SWAT. This is a major update to the first AGWA ArcGIS release (2.0 version)
Description:
The Automated Geospatial Watershed Assessment (AGWA) tool has been developed under an interagency research agreement between the U.S. Environmental Protection Agency, Office of Research and Development, and the U.S. Department of Agriculture, Agricultural Research Service. AGWA is an assessment tool that uses widely available data to run two hydrologic models (KINEROS2 and SWAT). It was designed to be easily applied by managers and scientists to evaluate likely outcomes of management scenarios and rank different areas in a watershed in terms of likely consequences to change. It was also designed to perform watershed analyses over large areas such as entire basins and to evaluate problem areas at the subwatershed scale to include small communities or rural areas. AGWA has been tested in a wide variety of watersheds and geographies. Since its initial release in ArcView 3.x, AGWA has been downloaded over 8000 times by users spanning 163 countries.
