WebbThe degree of saturation(S) is a measure of the void volume that is filled by water, expressed as a percentage ranging from 0 to 100. It is defined as: S V V w v =×100 (%) For a completely dry soil S = 0%, and for a soil where the voids are completely filled with water (saturated soil) S = 100%. Soils below the water table are often saturated. WebbTable 1.
