During many ground-water investigations the quantitative phases of the work frequently require application of the Theis nonequilihrium formula. Existing literature on ground-water hydraulics describes in detail the manner in which this formula is to be used in determining the coefficients of transmissibility and storage of an aquifer. However, when quantitative analyses move into the realm of predictions, or treatment of multiple-well systems, the conventional computational processes become
