AB: A progress report on the development of the groundwater section of the Arc Hydro data model is presented. The Arc Hydro surface water data model is a synthesis of geospatial and temporal information that characterize a "hydrologic information system" which supports hydrologic analysis and modeling in the ArcGIS environment. In order to better describe the full hydrologic cycle a groundwater section is developed to be incorporated into Arc Hydro. The integration of the groundwater data model will enable the characterization of surface water and groundwater simultaneously within ArcGIS. Representing the 3-dimensional nature of the subsurface and describing the hydrogeologic architecture of groundwater systems in a GIS framework is an important aspect of this study. The data model is designed to be scalable and will support the management of regional scale data as well as site scale information. The model will also describe surface water - groundwater connectivity by connecting the existing surface water data model with the groundwater section developed. The representation of groundwater systems will be utilized to develop interfaces between the ArcGIS environment and groundwater models such as MODFLOW.
