Permeability is an important property influencing flow-through porous media. Seepage of water through earth dams, stability of slopes and ground water recharge are some of the problems related to permeability of soil. The accurate determination of permeability is a cause of concern to the hydraulic engineers. As the stratification of earth crust exists in any direction, the study of permeability of soil is imminent in multiple directions. Although ample work has been reported regarding the permeability of soil in horizontal and vertical directions, the work on inclined layer seems to be sparse in the literature. Therefore, permeability of sloping soil layer has been investigated in this paper. Four samples of fine sand were selected from different sites for the experimentation. Permeability has been determined for horizontal layer, for positively as well as negatively sloped layer. Inclination of layer was varied from 0° to ± 20°. With the increase in inclination with respect to horizontal, the permeability of positively sloped layer was found to increase, whereas for the negatively sloped layer, it was found to decrease. When the slope was increased from 0° to + 20°, the maximum deviation of − 27% was observed between the observed permeabilities of horizontal and positively sloped layer, whereas for the opposite slope, i.e., from 0° to − 20°, the maximum deviation found was 34%. For a constant slope, the permeability of the said layers was found to increase with the particle size.
