the capillary fringe is a saturated zone above the water table where water is affected by capillary forces. distribution of moisture in the vadose zone (Fig 8.1) grain sizes in soils (and thus pore sizes) vary over several orders of magnitude (Fig) look at sand gauges.
1 the zone between the ground surface and the water table where pore spaces of the rock or soil may be partly filled with air and partly with water is referred to as the unsaturated zone or vadose zone and water in this zone is referred to as soil moisture (Fig). recharge is the water entering the saturated zone. 2  in many parts of the world, groundwater is the only source of fresh water. 3  in the US about 10% of the rainfall becomes groundwater eventually.
