The authors have been published numerical results for transient flow of ground water by pumping up from a fully penetrating well in multi-aquifer. In previous paper, the numerical solution in the case of the transient ground water flow by pumping up from a well in two-aquifers without reakage have been reported. In this paper, the numerical calculation in the case of the transient flow of ground water by pumping up from a well in unconfined-confined aquifer system considering reakage through intermediate layer with low permeability are reported. The experimental examination are made for application of this numerical solution. As the results, close agreement between observed and calculated values is obtained. The aquifer constants in each layer can be estimated by applying the calculated results to experimental values. Moreover the discharge from individual aquifers into a well and the reakage rate through the low permeable layer are well calculated respectively.
