The authors have been published a numerical method for analyzing the transient flow of ground water by pumping up from a fully penetrating well in a multi-aquifer. In the previous paper, the numerical solution in the case of the transient ground water flow by pumping up from a well in an unconfined-confined aquifer systems considering leakage through an intermediate layer with low permeabililty has been reported. In this paper, the numerical solution for transient flow of ground water by pumping up from a well in a confined-confined aquifer systems considering leakage is reported. The experimental examinations are made for application of this numerical method. From the results, close agreement between the piezometric head distribution by observation and by calculation are obtained. The aquifer constants in each aquifer and the permeability in the intermediate layer can be estimated by applying the calculated values to experimental values. Moreover the discharge from individual aquifers into a well and the leakage rate through an intermediate layer with low permeabililty are well calculated respectively.
