Land managers of the Fort Gordon military installation in Augusta, GA were in need of a tool which would predict the effects to water quality produced by changes in land use as well as predict impacts of existing land use condition to the quality of water on and leaving the installation. Over the past ten years many studies have evolved which provided differing levels of integration between water quality models and geographic information systems software. The Hydrologic Unit Water Quality Tool is a software package developed by NRCS employees in Ft. Collins, Colorado, which provides an intermediate integration between AGNPS and GRASS. The overall purpose of this study was to evaluate the use of this software as an aide in modeling water quality for Fort Gordon.
