A stiff clay layer of 11.02 m thickness with a unit weight of 17.52 kN/m³ overlies a sand layer. The ground water table is at the ground surface. A large open excavation was made in the stiff clay and when the depth of the excavation reached 8.52 m, the bottom rose, gradually cracked, and was flooded from below by a mixture of sand and water. Compute the elevation (m) to which the water would have risen from the sand into a drill hole if such a hole had been drilled before the excavation was started.
