WebbFrom the Surface into the Ground. Figure 11.8.1: Zone of saturation. When surface water infiltrates or seeps into the ground, it usually enters the unsaturated zone (a.k.a. vadose zone, a.k.a. zone of aeration). The vadose zone is the volume of material between the land surface and the zone of saturation, which consists of geologic materials in ... WebbThe height above the water table to which the soil is saturated is called the capillary rise, and this depends on the grain size and type (and thus the size of pores): · in coarse soils capillary rise is very small · in silts it may be up to 2m · in clays it can be over 20m Pore water and pore air pressure Pore pressure

Webb• If pore size is small and relatively uniform, it is possible that soils can be completely saturated with water for several feet above the water table. • Alternately, the saturated portion will extend only a few inches above the water table when pore size is large. • Saturated zone is classified into 4 categories.
