What is the saturated zone and unsaturated zone?

The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1).

Also asked, what is the difference between saturated zone and unsaturated zone?

Unsaturated zone: The area between the soil-water belt and the water table where pore spaces are not saturated with water. Saturated zone: The zone of rock below and including the water table where pore spaces are completely filled with water.

what is zone of saturation in groundwater? The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers.

Beside above, what does unsaturated zone mean?

The unsaturated zone is the portion of the subsurface above the groundwater table. The soil and rock in this zone contains air as well as water in its pores. Unlike the aquifers of the saturated zone below, the unsaturated zone is not a source of readily available water for human consumption.

What is vadose zone in geology?

The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin for "shallow").
