Detailed explanation-1: -1.3 Saturated Zone-Aquifers. The saturated zones that lie directly beneath the vadose zone are commonly called aquifers and are composed of porous parent materials that are saturated with water.

Detailed explanation-2: -Beaches and coasts, for example, will have zones of saturation that are very close to the surface. The water table can also be higher or lower, depending on where the top of the zone of saturation is. The water table can rise or fall due to natural events such as heavy rain, droughts, and flooding.

Detailed explanation-3: -The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table. Where raw wastewater is exfiltrating from a sewer pipe, the area of soil that is moistened around the leak point is often called the zone of saturation.

Detailed explanation-4: -The upper surface of this water-filled area, or “zone of saturation", is called the water table.

Detailed explanation-5: -The saturated zone lies below the zone of aeration and is the layer where the pores of the soil or rock are completely filled with water. 4. The groundwater table is the upper surface of the saturated zone.
