ABSTRACT: Water resources management in Georgia has become increasingly complex. Recent droughts, lawsuits by neighboring states, and in-state competition for water have created a patchwork of new regulations on water withdrawal permits. In some watersheds, streams have designated protection corridors; in others, subwatersheds have withdrawal limitations. In order to efficiently and objectively apply location-specific regulations, State agency hydrologists and geologists need geospatial evaluation tools. This research develops methodologies for joining and relating spatial and temporal data using the Arc Hydro data model and geodatabase functionality for surface water evaluations. The features contained within this hydrologic information system are employed as inputs to the process model, which is in turn used to create appraisal reports. The research was done under contract to the Georgia Department of Natural Resources, Environmental Protection Division.
