Abstract
A new computer modeling package has been developed through cooperative agreement between Indiana University, the University of Minnesota, and the U.S. Environmental Protection Agency for the determination of time-of-travel capture zones in relatively simple geohydrological settings. The WhAEM package includes an analytic element model that uses superposition of (many) closed form analytical solutions to generate a ground-water flow solution. WhAEM consists of two executables: the preprocessor GAEP and the flow model CZAEM. WhAEM distinguishes itself from existing analytical models in that it can handle fairly realistic boundary conditions such as streams, lakes, and aquifer recharge due to precipitation. The Geographical Analytic Element Preprocessor (GAEP) is designed to simplify input data preparation, specifically to facilitate the interactive process of ground-water flow modeling that supports capture zone delineation. The Capture Zone Analytic Element Model (CZAEM) is equipped with a novel algorithm to accurately define capture zone boundaries by determining all stagnation points and dividing streamlines in the flow domain.
