What is the unsaturated zone also called?
The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin word for "shallow").
What is an unsaturated water zone?
The unsaturated zone is the portion of the subsurface above the groundwater table. The soil and rock in this zone contains air as well as water in its pores.
What is the area above the water table known as?
vadose zone The water table sits on top of what experts call the zone of saturation, or phreatic zone. The area above the water table is called the vadose zone.
What is the zone above the water table called quizlet?
A subsurface zone above the water table where the rock or soil may be moist but not saturated, with air occupying some or all of the pore space; also called the unsaturated zone.
What is the unsaturated zone quizlet?
Unsaturated zone: The area between the soil-water belt and the water table where pore spaces are not saturated with water. Saturated zone: The zone of rock below and including the water table where pore spaces are completely filled with water.
What is saturation zone?
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.
Where is the unsaturated zone?
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.
What is the top of the saturated zone known as?
the water table The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.
What is the zone of saturation quizlet?
What is the zone of saturation? area where water fills all the open spaces in sediment and rock (groundwater is found here!)
Is water in the unsaturated zone called groundwater?
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.
What is the top of the saturation zone called?
The upper surface of this zone of saturation is called the water table. The saturated zone beneath the water table is called an aquifer. Aquifers are huge storehouses of groundwater. There are two types of aquifers: unconfined and confined.
What is saturated and saturation zone?
What is a zone of saturation? The zone of saturation is the portion of underground soil where all gaps are completely filled with water. In general, all of the soil and rock that is underground is divided into the zone of aeration and the zone of saturation.
What is the aerated zone?
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.
Is water in the unsaturated zone called groundwater quizlet?
Water in the Unsaturated Zone is called Soil Moisture, not Groundwater.
What is saturated catchment zone?
The saturated zone encompasses the area below ground in which all interconnected openings within the geologic medium are completely filled with water . Many hydrogeologists separate this zone into two subzones: the phreatic zone and the capillary fringe.
Is an aquifer the saturated zone?
4.2. 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. Like the vadose zone, aquifers are generally oligotrophic environments.
What are the 3 zones of groundwater?
Water beneath the surface can essentially be divided into three zones: 1) the soil water zone, or vadose zone, 2) an intermediate zone, or capillary fringe, and 3) the ground water, or saturated zone.
