Dug wells in the Deccan basalts of India can provide a means of determining the permeability of the unconfined aquifer within the weathered layer. The layered nature of this aquifer, together with its low permeability, produces a complicated ground‐water flow pattern around large‐diameter dug wells when they are pumped. A digital model, which successfully simulated the head distribution in and around a large‐diameter pumping well demonstrated that recovery, rather than drawdown, data from such tests are more suitable for analysis.
