A procedure is described for automated fitting of test data for pumping from an unconfined aquifer of semi‐infinite thickness. The fitting is achieved by sensitivity analysis and the least‐squares method. The early time data are fitted to the Streltsova (1974) model and the late time data are matched to the Dagan (1967) model. These solutions are useful where the aquifer thickness is extensive and unknown. Data from a test in the Indus Basin, Pakistan, was analyzed to test this procedure.
