.Values of transmissivity and storage commonly are derived for a nonleaky confined aquifer by manual curve matching of pumping‐test data. Automatic matching of pumping‐test data with the Theis type curve is possible using the method of least squares, provided the Cooper‐Jacob approximation of the well function W(u) is considered. A FORTRAN program was developed to carry out this automated matching. Results derived from published data show that the method gives parameters close to the ones derived by the standard method of manual curve matching.
