Solutions for the drawdown distribution due to the operation of well fields in coupled leaky aquifers of infinite areal extent are available. This paper is concerned with the drawdown distribution caused by the pumping of well fields in coupled leaky aquifers of finite areal extent. A transform to solve the flow problem is obtained by the modification of the zero‐order Hankel transform. Two cases of the problem are analyzed. Case 1 concerns the upper aquifer when it is confined or unconfined and the drawdown in it is very small compared with its saturated thickness. Case 2 concerns the upper unconfined aquifer when the drawdown in it can be significant in relation to its saturated thickness. Approximate solutions and solutions for special cases are obtained in addition to the exact solutions. The solutions are in the form of series that can readily be evaluated.
