A soil layer is saturated and has a unit weight of water of 9.81 kN/m³. If the groundwater level is at 5m, calculate the pore water pressure at a depth of 12m.
💡 Hint: Remember to subtract the depth from the groundwater level.
Describe what happens to pore water pressure when a heavy load is applied to saturated soil and predict how effective stress will change.
💡 Hint: Think about how water adjusts to stress changes and how this affects strength.
