This paper deals with the analysis of groundwater flow in nonuniform homogeneous media. With the aid of a stochastic approach and directly using the convolution integral, the effects of stochastic parameter distributions on predicted hydraulic head are analyzed without resorting to Monte Carlo simulations. The input parameters, transmissivity and storage coefficient in this study, are assumed to be normally distributed, and the output is the statistical distribution of hydraulic head, through space and time, as indicated by the expected values and their standard deviations. Though the restrictive numerical limitation exists, the transmissivity coefficient plays the more important roles in both the average value and the standard deviation compared with the storage coefficient. The results of this research may become good references for the simulation approach in the actual watersheds.
