GEOLOGY

Detailed explanation-1: -A water table–or unconfined–aquifer is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall.

Detailed explanation-2: -The upper surface of this water-filled area, or “zone of saturation", is called the water table. The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water.

Detailed explanation-3: -water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it.

Detailed explanation-4: -WATER TABLE: The top of an unconfined aquifer; indicates the level below which soil & rock are saturated with water. CONFINED AQUIFER: An aquifer that is bounded above & below by non-permeable layers that transmit water significantly more slowly than the rest of the aquifer.

Detailed explanation-5: -The unconfined aquifer is also known as the water table aquifer and phreatic aquifer. An impervious layer is generally served as the bottom boundary of an unconfined aquifer and the top layer is not confined.
