The sheet pile wall shown below is embedded in a 10-m thick deposit of silty sand, overlying hard clay. The silty sand has a saturated total unit weight of 19.0 kN/m ³ , 15% fines, USCS classification of SM, and hydraulic conductivity of 0.0001 cm/s. The hard clay has a total unit weight of 18 kN/m ³ , plasticity index of 35, and hydraulic conductivity of 1.0 x 10-7 cm/s. Determine the maximum height (DH) that the water on the left side of the wall can reach before "boiling" or "heave" is expected to occur on the right side of the wall. Note that the water level on the right side will coincide with the ground surface.
