A layer of saturated clay 5 m thick is overlain by sand 4.0 m deep. The water table is 3m below the top surface. The saturated unit weight of clay and sand are 18kN/m3 and 20KN/m3 respectively. Above the water table, the unit weight of sand is 17KN/m3. Calculate the effective pressure on a horizontal plane at a depth of 9 m below the ground surface. What will be the increase in the effective pressure at 9m if the soil gets saturated by capillary, up to height of 1m above the water table? Yw = 9.81KN/m3.

A layer of saturated clay 5 m thick is overlain by sand 4.0 m deep. The water table is 3 m below the top surface. The saturated weights of clay and sand are 18 kN/m3 and 20 kN /m3, respectively. Above the water table, the unit weight of sand is 17 kN/m3. Calculate the effective pressure on a horizontal plane at a depth of 9 m below the ground surface. What will be the increase in effective pressure at 9 m, if the soil gets saturated by capillary up to height of 1 m above water table?
A horizontal column of 100 cm length and 10 cm height is packed with a uniform soil with a saturated hydraulic conductivity of 4×10–5 cm/s. Then, the uppermost 1.0 cm is replaced with a soil with a saturated hydraulic conductivity of 2.2×10–7 cm/s. Therefore, the horizontal column has two horizontal layers. The pressure head is 20 cm at the left end (X = 0 cm; inflow boundary) of the column and 150 cm at the right end (X = 100 cm; outflow boundary). Flow is horizontal and steady state. For horizontal flow, the pressure head is the only driving force (gravitational head = 0). The volumetric water content of both soils is equal to the porosity and is 0.45 cm3/cm3. (A) Determine the effective saturated hydraulic conductivity of the layered soil column. (B) Calculate the Darcy’s flux through the layered soil column. (C) Calculate the Darcy’s flux in the top and bottom layers of the soil column.
