plot the distribution of total stress effective stress and pore water pressure with depth for the soil profile shown in figure.Negative capillary action and pore air pressure.If the groundwater in problem were (a)to rise to the surface.(b)to rise 2 meters above the surface and (c)to rapidly decrease from 2 meters above the surface to 1 meter below its present level.determine and plot the distribution on vertical effective and total stress and porewater pressure with depth.
