WhAEM 2000 is a public domain, ground-water flow model designed to facilitate capture zone delineation and protection area mapping in support of the State's Wellhead Protection Programs (WHPP) and Source Water Assessment Planning (SWAP) for public water supplies in the United States. Program operation and modeling practice is covered in a series of progressively more complex representations of the wellfield tapping a glacial outwash aquifer for the city of Vincennes, Indiana. WhAEM2000 provides an interactive computer environment for design of protection areas based on radius methods, well in uniform flow solutions, and geohydrologic modeling methods. Protection areas are designed and overlaid upon US Geological Survey Digital Line Graph (DLG) or other electronic base maps. Base maps for a project can be selected from a graphical index map for the State. Geohydrologic modeling for steady pumping wells, including the influence of hydrological boundaries, such as rivers, recharge, and no-flow contacts, is accomplished using the analytic element method.

New Features

• USGS Digital Raster Graphics files (DRGs) in GeoTIFF format are now supported as base maps.
• A tool for adding simple Wellhead Protection Areas (WHPAs) has been included.

Known Deficiencies

• Unhandled Error will occur when adding binary base maps (BBMs) to a new project under Windows95, when the project is created in the c:\Program Files\WhAEM path. The work around is to create all new projects under a different path, say c:\WhAEM.DAT\.
• There is an incompatibility of the Tool convert DLG to BBM for some USGS maps. We are working to fix this.

SYSTEM REQUIREMENTS

• Intel 80486 DX/66 or higher microprocessor system (Intel Pentium highly recommended)
• Windows 95, 98, Windows NT 4.0, 2000, or XP operating system
• 25 MB free disk space
• 16 MB memory (32 MB or more gives MUCH improved performance)
• VGA display or better (SVGA in resolutions with 800x600 or higher resolution give best results)
• Mouse or other pointing devise
• Windows compatible printer (optional)
