A fully three dimensional model of variably saturated flow has been developed to investigate the hydrological effects of spatial variability of saturated hydraulic conductivity on a 150 m by 100 m hillslope and assess the validity of the concept of effective hydraulic conductivity. The model is based on the Galerkin approximation to the finite element method. Accessibility to the vector processor of a CDC Cyber 205 supercomputer permitted numerical solutions on grids containing several thousand node points and two thousand time steps. The results suggest that under conditions of predominant subsurface flow the concept of equivalent uniform properties are valid. -Authors
