WebWhen computing total vertical stress, use saturated unit weight for soil below the water table and bulk or dry unit weight for soil above water table. When the soils are partially saturated, the situation is a bit more complex. Here, the normal stress within a soil element is carried by the water, air, and the soil grains. Therefore, the WebHowever, the partially saturated zone, a critical region that links the earth's surface to aquifers, has to date received only minor attention in the context of ENP mobility. We …
