A slope is to be constructed in a soil for which c̅ = 0 and ϕ = 30°. It is to be assumed that the water level may occasionally reach the surface of a slope, with seepage, taking place parallel to the slope. Determine the maximum slope angle for a factor of safety 1.5, assuming a potential failure surface parallel to the slope if the saturated unit weight of the soil is 19 kN/m3.
