Effect Of Water Table On Effective Stress - Know More

Hence with all our calculations we observed that change in the water level above the ground does have no effect on effective stress and it remains unchanged As we can see the height of the water above the surface is not in any equation, because increased height of the water above the ground level causes to increase in the total stress as well as the pore water pressure...
