The soil profile consists of a 15 m layer of sand underldin by a 25 m layer of clay. The location of water table is 5 m from the ground surface. The unit weight of sand above the water table is 20.11 kN/m3 and below, the saturated unit weight of sand is 21.43 kN/m3. The clay has a saturated unit weight of 17.82 kN/m?. If the effective pressure at the bottom of sand is 81.9 kPa, what height above this point the water will rise in the piezometer?
