For the soil profile below, answer followings:

A$.$ Suppose that the saturation above water table is $25\%,$ but the capillary rise zone is fully saturated with water. Also suppose that pore water pressure above capillary rise zone is zero. Compute and plot profiles of following stresses. The plots should span from the depth range of $0m$ to $12m$ from surface.

i$.$ Vertical total stress, ${}_v$

ii$.$ Pore pressure, $u$

iii. Vertical effective stress, $\text{'}$

iv$.$ Horizontal effective stress, $\text{'}$h

v$.$ Horizontal total stress, ${}_h$

B$.$ Sketch a block diagram for the clay at a depth of $8m,$ and include the vertical and horizontal effective stresses on the block diagram. Note that the shear stresses on horizontal and vertical planes are zero for level ground conditions.
