A soil profile consists of a clay layer underlain by a sand layer, as shown in Figure. If a tube is inserted into the bottom sand layer and the water level rises to 1 m above the ground surface, determine the vertical effective stresses and porewater pressures at A, B, and C. What is the value of the porewater pressure at A to cause the vertical effective stress there to be zero?
