A soil profile consists of 3m of clean sand (γ=18kN/m³) over 10m of silt (γ=17kN/m³, kv=1 x 10-8m/s) over 12m of clay (γ=17kN/m³, kv=4 x 10-9m/s) over gravel. Piezometers installed at middepth of the sult later and at the top of the gravel layer measure, respectively, piezometric heads of 4m and 3m. Assuming one-dimensional flow in the vertical direction, compute the flow rate in m³/year/10,000m². Also, compute at 16m below the ground surface the total veritcal stress, effective stress, and porewater pressure.
