The upper zone, called the zone of aeration, is where a mixture of water and air fills the pore spaces. Below the zone of aeration is the zone of saturation, where the pore spaces are completely filled by water. The upper boundary of the zone of saturation is known as the water table. Aquifers are found in the area saturated with water.The zone of aeration consists of the upper layers of soil in which there is air-filled porosity, pores or pockets filled with air rather than water. If toxic spills occur, chemicals move …The unsaturated, vedose or aeration zone is further classified into three sub zones:-. a. Soil – water Zone: This begins at the ground surface and extends downward through the major root zone. Its total depth is variable and dependent upon soil type and vegetation. The zone is unsaturated except during periods of heavy infiltration.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. CONE OF DEPRESSION: Pumping from a well in a water table aquifer lowers the water table near the well. This area is known as a cone of depression.The zone above the water table that contains both air and water within the pore spaces of soil, sediment, or rock. Zone of saturation. The area below the water table in which all pore spaces are filled with water. Water table. The surface that separates the zone of aeration from the underlying zone of saturation. Capillary fringe.Rain that falls on the surface seeps down through the soil and into a zone called the zone of aeration or unsaturated zone (also called the vadose zone), where most of the pore spaces are filled with air. As it penetrates deeper it eventually enters a zone where all pore spaces and fractures are filled with water.Groundwater is the water which occurs in the zone of saturation where all interconnected voids are filled with water under hydrostatic pressure, while vadose water is the water which occurs in a zone of aeration where interstices are filled partly with water and partly with air (Todd and Mays, 2005). Groundwater is generally less vulnerable to ... Water seeps through the zone of aeration to the zone of saturation where openings in soil and rock are completely filled with water. The top of the zone of saturation is called the water table. Where the water table intersects the ground surface, springs and streams form. Note that the depth of the water table varies with the topography. Groundwater forms when surface water is pulled down by gravity permeates the zone of aeration, which is the top layer of sediment with pore space filled with water and air, and then settles in the ...Above this zone is the unsaturated / partially saturated zone (these terms have replaced the term zone of aeration).
