A deep basement for a building is constructed in dense granular soil whose unit weight is 126 pcf (19.8 kN/m³). Assume K_O
= 0.40. For a point 10 ft (3 m) below the ground surface, estimate the increase in total lateral pressure that results by having the water table change from a location below the basement level to the ground surface (in psf and kPa). Assume the submerged unit weight for the soil is half the indicated unit weight (the given unit weight is a wet but not saturated unit weight).
