Extracted text: A granular soil deposit is 4 m. thick and underlying it is a clay having a thickness of 5 m. There is a water table at the interface of the soil and the clay. Unit weight of sand is 15.6 kN/m and saturated unit weight of clay is 17.8 kN/m. O What is the effective stress at the bottom of the clay? O If the water table rises to the level of the soil surface, what is the effective stress at the bottom of the clay? O f the water is 3 m. above the soil surface, what is the effective stress at the bottom of the clay?
