An artesian aquifer (i.e., confined water table) is shown in Figure (A1-1) where an observing well is drilled to monitor the water level in Point \( (\mathbf{A}) \). You are required to calculate the magnitudes of total stress, pore water pressure and effective stress in Point (A) in KPa. Specific unit weight of water is \( 9.81 \mathrm{kN} / \mathrm{m}^{3} \). Water level in the observing well is \( 2 \mathrm{~m} \) above the saturated sand layer. Figure (A1-1): Artesian aquifer between clay and bed rock surface (NOT to scale)
