A soil profile of sand (9m thick) which overlies a layer of clay (5m thick). Ground water table is located at the interface of the sand and clay. The effective stress at the bottom of the clay layer was determined. If the water table rises to the top of the ground surface, what is the change in effective stress (in kpa) at the bottom of the layer? for sand layer: void ratio = 0.88, specific gravity = 2.71, degree of saturation = 0.76 for the clay layer: void ratio = 1.07, specific gravity = 2.81

Question
A soil profile of sand (9m thick) which overlies a layer of clay (5m thick). Ground water table is located at the interface of the sand and clay. The effective stress at the bottom of the clay layer was determined. If the water table rises to the top of the ground surface, what is the change in effective stress (in kpa) at the bottom of the layer?
for sand layer:
void ratio = 0.88, specific gravity = 2.71, degree of saturation = 0.76
for the clay layer:
void ratio = 1.07, specific gravity = 2.81
