Abstract: The effects of spatial variability of aquifer transmissivity on regional groundwater flow and solute transport are investigated using the spectral method. In particular, we emphasize the influences of horizontal anisotropy of the transmissivity field on the variances of head, velocity, and concentration. Closed-forms of the variances which related to the statistical parameters of log-transmissivity are developed for steady flow in a two-dimensional infinite domain. Important roles of the horizontal anisotropy on the flow and transport phenomena are explained based on the theoretical results.
