ABSTRACT
Unfortunately, conceptual models are rarely properly defined before aquifer test data are analyzed. As a result, analysis often proceeds with an invalid or inadequate understanding of the groundwater flow system. This can lead to confusion and erroneous conclusions about aquifer and confining unit characteristics. Therefore, the first step in aquifer test modeling should be conceptual model definition. In a sense, the conceptual model is the aquifer test modeling database. A conceptual model provides a frame of reference and direction for the entire aquifer test modeling process.
