Question

The surface of a deposit of clay is horizontal and the water table is located at the surface. A. Compute the pore water pressure at point a located 1.52 m below the ground surface. B. Compute the pore water pressure at the same point when water table has dropped to 3.04 m below the ground surface. Assume the clay above the water table remains 100% saturated (pores well connected with water to the height of earlier water table). C. Does the drop in water table change the effective and total stress at point a and if so, by how much?
