Abstract . A program that will calculate aquifer transmissivity from the specific capacity of a well has been developed for handheld programmable calculators. The program extends the approach of Theis and others (1963) beyond the visual graphical interpolation of transmissivity values from type curves and solves directly a nonlinear equation for transmissivity, using a modified Regula Falsi solution algorithm. The program eliminates errors associated with visual interpolation of transmissivities obtained from type curves, especially for values of small transmissivities, and provides a quick and portable method of obtaining transmissivity values onsite.
