A 3.0 m wide square foundation is placed at 1.5 m depth in sand where γ = 18.5 kN/m³. The water table lies well below the foundation level. Under the applied pressure of 200 kN/m² at the foundation level, the settlement recorded was 14.0 mm. It is expected that the water table will rise in the future to unknown levels. Plot the expected additional settlement against the water table rise. Discuss the rate of rise in the additional settlement with the water table rise. Use the method of Shahriar et al. (2014) (Section 9.10).
