Which of the following is defined as the line of contact between the zone of aeration and the zone of saturation?
water deficits in summer months. The line of contact between zone of aeration and the zone of saturation is known as the. water table.
What is the zone of aeration quizlet?
zone of aeration. zone of aeration is the region between the earth's surface and the water table. The main components of this region are the soil and rocks. Their pores are at times partly filled with water and air, and aeration occurs when the air and water mix or come into close contact. water table.
Which is defined as the downslope Unchannelized flow of water across the surface?
The downslope, unchannelized flow of water across the surface is known as. overland flow.
What does the term groundwater mining refer to?
The term "groundwater mining" refers to. the removal of groundwater at a rate faster than that at which it can be replaced. The term "cone of depression" refers to. a depression in the water table formed by rapid groundwater withdrawal.
What is zone of saturation in groundwater?
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).
What does zone of aeration mean?
The zone of aeration is the region between the earth's surface and the water table. The main components of this region are the soil and rocks. Their pores are at times partly filled with water and air, and aeration occurs when the air and water mix or come into close contact.
What is the top of the zone of saturation?
the water table 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). The water table may be just below or hundreds of feet below the land surface.
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.
Which is defined as the portion of streamflow that consists of groundwater?
Base Flow. The portion of streamflow that consists of groundwater.

What does recharge zone mean?
Recharge zones refer to those areas where water infiltrates through the permeable rock and sediment but the saturated zone is at a depth where surface ecosystems (e.g. palustrine, lacustrine and riverine wetlands, riverine water bodies and terrestrial vegetation) are unable to access the groundwater.
What is meant by water resources explain renewable and non renewable water resources?
Non-renewable water resources are not replenished at all or for a very long time by nature. This includes the so-called fossil waters. Renewable water resources are rechargeable due to the hydrological cycle unless they are overexploited, comprising groundwater aquifers and surface water like rivers and lakes.
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 another name for the zone of saturation?
the phreatic zone Maximum corrosion occurs at the intermediate of the two extremes of soil-moisture content. The zone of saturation is also known as the phreatic zone.
What is another name for the zone of aeration?
The zone of aeration is also known as the unsaturated area, vadose zone or zone of suspended water.
What is under the zone of saturation?
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.
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.
How are the zone of aeration and the zone of saturation the same?
Thus, the zone of aeration forms the top layer through which water penetrates, and the saturation layer is where it gets held and stored. Both zones work together to store water in the water table.
What is interflow and baseflow?
Interflow, also known as subsurface runoff is relatively rapid flow toward the stream channel that occurs below the surface. It occurs more rapidly than baseflow, but typically more slowly than surface runoff.
What is the definition of streamflow?
Definition of streamflow : water flowing in a stream channel specifically : the velocity and volume of such water.
Where is the saturated zone?
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). The water table may be just below or hundreds of feet below the land surface.
Which zone is a zone of non saturation among vadose water?
The intermediate vadose zone Which zone is a zone of non-saturation among vadose water? Explanation: The intermediate vadose zone occurs immediately below the zone of soil water. It is in fact a zone of non-saturation: water in this zone is moving downwards under the influence of gravity. 13.
What is the surface of the zone of saturation known as?
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 a Artesian zone?
Artesian Zone: where the water pressure brings water to the surface naturally. Karst: a landscape, often made of limestone, with sinkholes and caves. Well: a human-made hole in the ground, dug to pump out water. Spring: a place where water flows from the aquifer to the surface.
What is meant by natural resources explain renewable and non-renewable natural resources?
Natural resources are materials or things that people use from the earth. There are two types of natural resources. The first are renewable natural resources. They are called renewable because they can grow again or never run out. The second are called nonrenewable natural resources.
Why are coal petroleum and natural gas considered nonrenewable resources if they were produced from plant and animal remains?
Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time.
What is saturated zone and 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. The top of the saturated zone is called the water table (Diagram 1).
What is the unsaturated zone called?
the vadose zone The unsaturated zone, often called the vadose zone, is the portion of the subsurface above the water table. It contains, at least some of the time, air as well as water in the pores. Its thickness can range from zero, as when a lake or marsh is at the surface, to hundreds of meters, as is common in arid regions.
Which zones are together called zone of aeration?
Which zones are together called zone of aeration? Explanation: The intermediate zone is generally of small thickness and may be even absent in many cases. The soil water and intermediate zones are sometimes collectively referred to as the zone of aeration.
What is meant by zone of saturation?
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.
