Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The stability of shore bluffs against seepage erosion was investigated by a FEM seepage analysis. Very high hydraulic gradients within the sensitive silt stratum were obtained for k values lower than 1 x 10-4 cm s-1. Anistropic permeability changes the orientation of hydraulic gradient vectors and thus increases the stability of bluff slopes. Stability against seepage erosion depends on the magnitude and direction of hydraulic gradient vectors as well as on soil geotechnical properties"--Abstract, page 1.
