THE ARC HYDRO GROUNDWATER DATA MODEL AND TOOLS

摘要

Arc Hydro Groundwater (AHGW) is a data model for managing groundwater data. It is an extension to the Arc Hydro surface water data model and is designed to support various types of groundwater data in ArcGIS, including well/borehole data, geologic map data, representation of 2D and 3D hydrogeologic models, and data from groundwater simulation models. We have developed a suite of tools in partnership with ESRI to support the AHGW data model. The tools are divided into three categories: Groundwater Analyst provides a suite of tools for importing groundwater datasets such as wells and time series of water levels and water quality data into the geodatabase. Tools in the Groundwater Analyst suite help create common products such as water level, water quality, and flow direction maps. Subsurface Analyst provides a suite of tools to create, edit, and visualize 2D and 3D hydrogeologic models within an ArcGIS, starting with classification and visualization of borehole logs, creation and editing of cross sections, and the generation of 3D volumes and fence diagrams. MODFLOW Analyst contains tools that allow the user to create, edit, archive, and visualize MODFLOW models within ArcGIS. The tools in MODFLOW analyst provide an option to import an existing model into a geodatabase and geo-reference the model so one can visualize and analyze the results in context with other GIS data, as well as create new models or edit existing models using GIS datasets. The MODFLOW Analyst tools are built as geoprocessing tools that can be used for building high-level custom workflows.
