At shallower and deeper zones, the soil and the rocks are unsaturated and the pores in the rocks contain some spaces from where the air can pass and is not completely filled by the water from above and below this layer is the saturated zone where the soil pores are completely filled with water.
As the groundwater may be in a confined and confined zone the water travels through the beds and it extends with the uniform permeability to the surface in both discharge and recharge zones.
<u>The vadose zone s the unsaturated part that s located above the groundwater and thus the soil and rocks are not fully saturated with the water and pore thus contain air and water with them.</u>
