I need help on this hydraulic problem. Thank you Derive an expression for the critical hydraulic head for which a column of saturated sediments with the thickness H will reach ‘quicksand conditions’ (i.e., the effective vertical stress is zero). For simplicity, assume that the water table is at the sediment surface. Once you derive the formula, calculate how fast groundwater must flow upward to reach the quicksand conditions assuming a range of hydraulic conductivities characteristic for fine-grained sands (between 10^-7 and 10^-4 m/s). Assume that the saturated density of sands is 2,000 kg/m^3.
A soil profi le consists of a clay layer underlain by a sandlayer, as shown in Figure P7.17. If a tube is inserted intothe bottom sand layer and the water level rises to 1 mabove the ground surface, determine the vertical effective stresses and porewater pressures at A, B, and C. IfKo is 0.5, determine the lateral effective and lateral totalstresses at A, B, and C. What is the value of the porewater pressure at A to cause the vertical effective stressthere to be zero?
