There is a decrease of lateral pressure

The ratio of the volume of voids and the volume of solids.

Void Ratio

The groud water table is located at a certain depth below the ground surface. This will cause an upward seepage. What would be the resulting effective stress at a certain point below the ground water table due to the upward seepage?
