The Automated Geospatial Watershed Assessment (AGWA) is an ArcGIS interface to support data organization, model parameterization, integration, and visualization for KINEROS2, RHEM, and the Soil Water Assessment Tool (SWAT) model. All of the required initial modeling parameters automatically are generated by AGWA from topography, soils, and land cover/land-use Geographic Information Systems (GIS) data layers. Built into AGWA are digitized and interpolated versions of the National Oceanographic and Atmospheric Administration (NOAA) technical publication 40 (TP40) rainfall frequency atlas maps. There are potential long-term implications of these results as well for overall plant productivity. The current RHEM and AGWA tools, as well as those in development, will support the analysis of alternative management systems as well as their placement in a watershed to reduce conservation investments and increase cumulative conservation benefits over a range of scales.
