A soil layer exists in a tank with upward seepage. If Hi = 0.91 m, H2 = 1.37 m, h = 0.46 m, ysat = 18.67 kN/m', area of the tank = 0.58 m2, and hydraulic conductivity of the sand (k) = 0.16 cm/s, a) What is the rate of upward seepage of water (m'/min)? b) Draw the diagrams of variation of total stress, pore water pressure, and effective stress with depth for a soil layer. c) If the point C is located at the middle of the soil layer, then what is the effective stress at C? d) What would be the critical value of h to cause boiling?
