Description:
The Wellhead Analytic Element Model (WhAEM) demonstrates a new technique for the definition of time-of-travel capture zones in relatively simple geohydrologic settings. he WhAEM package includes an analytic element model that uses superposition of (many) analytic solutions to generate a ground-water flow solution. hAEM consists of two executables: the preprocessor GAEP, and the flow model CZAEM. hAEM differs from existing analytical models in that it can handle fairly realistic boundary conditions such as streams, lakes, and aquifer recharge due to precipitation. he preprocessor GAEP is designed to simplify input data preparation; specifically it facilitates the interactive process of groundwater flow modeling that precedes capture zone delineation. he flow model CZAEM is equipped with a novel algorithm to accurately define capture zone boundaries by first determining all stagnation points and dividing streamlines in the flow domain. o models currently in use for wellhead protection contain such an algorithm.
