In the soil profile shown below, if the water table changes from level WT0 to level WT1 permanently, what is the change in the ground surface elevation in mm in the long term after primary consolidation is completed? Assume that the clay layer is initially normally consolidated. Use a single clay layer in your calculations and positive value for settlement. (Acceptable tolerance = 4%)
