Detailed explanation-1: -The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. Water pressure and atmospheric pressure are equal at this boundary.
Detailed explanation-2: -The upper surface of this zone of saturation is called the water table. The saturated zone beneath the water table is called an aquifer, and aquifers are huge storehouses of water. What you are looking at in this picture is a “well” that exposes the water table, with an aquifer beneath it.
Detailed explanation-3: -The upper surface of this water-filled area, or “zone of saturation", is called the water table.
Detailed explanation-4: -The water table is the upper surface of the saturated zone in an unconfined aquifer. A confined aquifer has a potentiometric surface (instead of a water table), which is defined as the level to which water would rise if a well were drilled into the confined aquifer.
