Underneath the . water table is the saturated zone, where water fills all spaces between sediments. The saturated zone is bounded at the bottom by impenetrable rock. Zone of aeration has less water held to the soil and rocks by capillarity force, whereas, zone of saturation are filled with water in all the rock spaces and its pores (Baldwin and McGuinness, 1963).

The upper surface of the saturated zone is called the water table. Contrary to popular belief, groundwater does not form underground rivers. It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that …Groundwater is found in two zones. 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).Figure A-1. The water table is the upper surface of the saturated zone. The water table meets surface-water bodies at or near the shoreline of surface water if the surface-water body is connected to the ground-water system. In contrast to the unsaturated zone, the voids in the saturated zone are completely filled with water. The zone that exists between the water table and the ground surface is called the zone of aeration. In order to be successful, a well must be drilled into the zone of saturation. The velocity at which water flows underground depends on the permeability of the rock or how large and well connected the openings are.

The water table is the upper surface of the saturated zone. The water table meets surface-water bodies at or near the shoreline of surface water if the surface-water body is connected to the ground-water system. In contrast to the unsaturated zone, the voids in the saturated zone are completely filled with water. 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. 5. Figure 12.9: The groundwater table: (a) intersects the land surface at lakes, marshes and streamszone that lies below it from the capillary fringe, or zone of aeration, that lies above it. The water table fluctuates both with the seasons and from year to year because it is affected by rainfall and climatic variation. It is also affected by the quantum withdrawal from wells or by artificial recharging.ZONE OF SATURATION: The area of a water-bearing formation in which all spaces between soil particles and rock structures are filled with water. ZONE OF AERATION: The area of an unconfined aquifer above the water table where the pore spaces among soil particles and rock formations are filled with air.Above this zone is the unsaturated / partially saturated zone (these terms have replaced the term zone of aeration).

In the zone of aeration, water moves downward due to gravity, but in the zone of saturation it moves in a direction determined by the relative heights of water at different locations. Water that occurs in the zone of saturation is termed groundwater.It travels horizontally below the surface but above the water table, in an area called the "zone of aeration" or "vadose zone," Baseflow (aka Groundwater Runoff): Baseflow is the direct seepage from groundwater into surface water, which can bring with it whatever chemicals the groundwater has collected for thousands of years moving ...The zone of aeration is further sub-divided into three layers—soil moisture zone, intermediate zone and capillary zone, collectively called Vadose Zone. Some amount of water in this zone is used by plants. At the bottom of the intermediate zone lies the capillary fringe (a thin layer of 2 to 3 cm) from where water moves upward.Aerators are essential pieces of equipment for any lawn care business.
