What is submerged unit weight

What is Submerged unit weight with respect to saturated unit weight? Saturated unit weight is equal to the bulk density when the total voids is filled up with water and Unit weight of water is the weight of watet per unit volume of a water.

Submerged density or bouyant density is the density of a mass of soil as observed under water in a saturated condition of course. Suppose you are calculating the density when the soil mass and you yourself are submerged. It is calculated as the difference of the soil density in air and the density of water, divided by the density of water.

It is also defined as the mass of soil minus the mass of water displaced by it upon submergence, divided by the volume. This concept is particularly useful in determining the bouyancy of submerged soils and is crucial in equations of sediment transport in rivers.

If the bouyant density equals 1, the soil just floats. If it gets negative, soil will rise in water. Degree of shrinkage is another concept. It is the amount of water content reduction needed to bring the soil to its shrinkage limit, expressed as percent of the original water content. The presence of organic material reduces the value of G s. Dry unit weight is a measure of the amount of solid particles per unit volume. Bulk unit weight is a measure of the amount of solid particles plus water per unit volume.
