void ratio of sample 1 at 600 mm depth is about 0.7, which is much higher than the initial pre tsunami void ratio estimated to be less than 0.5 on the compacted surface. Assuming this range of void ratio and an associated saturated unit weight of about 21 kN/m3, the critical hydraulic gradient, icr, can be estimated from: icr= (Ys/Yw) - j
