(1993) restated this same range of values for residual saturation in both the vadose and saturated zones. Wilson et al. (1990) observed residual saturations in saturated unconsolidated sands to range from 0.14 to 0.30 (14% to 30%) and a lower value, 0.09 (9%), for one unsaturated (vadose zone) sand.
