The framework of GIS-based decision Support Systems (DSS) for water resources management at the Flint River Basin

In this paper, a surface water flow model with groundwater interaction for the Flint River Basin (FRB) is presented. The model consists of two layers of modeling systems which are HSPF hydrological model in first layer for streamflow simulation within subbasin and a Stella model in second layer for flow simulation in Flint River (main stream). To fully consider the dynamic interaction between surface and groundwater and more accurately simulate this complex water resources systems, a framework of dynamic surface and groundwater modeling systems is proposed for future improvement of current modeling systems. Furthermore, a framework of GIS-based decision support system (DSS) is constructed, which includes SW-GW modeling system, database, GIS-based user-friendly graphic interface, analysis tool, and alternative analysis and evaluation module. This DSS, when finished, may provide strong technical support for best managing water resources in Flint River Basin.Sponsored by: Georgia Environmental Protection Division U.S. Geological Survey, Georgia Water Science Center U.S. Department of Agriculture, Natural Resources Conservation Service Georgia Institute of Technology, Georgia Water Resources Institute The University of Georgia, Water Resources Facult
