The zone that exists between the water table and the ground surface is called the zone of aeration. In order to be successful, a well must be drilled into the zone of saturation. The velocity at which water flows underground depends on the permeability of the rock or how large and well connected the openings are.Oct 16, 2019 · When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water ( recharge) into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, though, and that must be considered when ... Zone of Aeration The zone of aeration, according to Meinzer (1, 2), has three principal divisions : 1.

The intermediate belt: "lies be-tween the belt of soil water and the ...

zone of aeration (upper zone), zone of saturation (lower zone). water table. The zone that water passes through, near the surface, before it settles. Water seeps through the zone of aeration to the zone of saturation where openings in soil and rock are completely filled with water. The top of the zone of saturation is called the water table. Where the water table intersects the ground surface, springs and streams form. Note that the depth of the water table varies with the topography.
