| Description | Well-head Analytic Element Model (WhAEM) is a single-layer steady-state groundwater flow model designed to delineate capture zones and isochrones of groundwater residence times for the purpose of wellhead protection. The program consists of two modules: GAEP (Geographic Analytic Element Preprocessor) and CZAEM (Capture Zone Analytic Element Model). CZAEM, an interactive, command-driven code, has extensive graphic capabilities to support the post-simulation analysis and presentation of results, including contours and pathlines. CZAEM is based on the Dupuit-Forcheimer assumption for horizontal 2D flow in an aquifer and includes elements for wells with either specified discharge or specified head at well boundary, and for line sinks. Various hydraulic features may be represented by a combination of well and line-sink elements, such as streams, well-fields, and lakes. Also, CZAEM supports a 'rain' element, allowing the introduction of recharge from precipitation. |
