Glossary of geography and geology terms Meaning and definition of permeability
Permeability
In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. Hence, it is the degree of magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the (italici…
What is the meaning of permeable material?
The definition of permeable is a material that allows liquids or gases to pass through. A cloth that liquids can pass right through is an example of something that would be described as permeable. Of or relating to substance, substrate, membrane or material that absorbs or allows the passage of fluids.
What is permeability of border?
Permeability, the degree of openness of borders, is of crucial importance for people living in borderlands. The twentieth century saw each type of border regime: closed, semipermeable, and permeable. Some border regimes even ceased to exist, at least in one certain respect, for example, in economic terms.
What does it mean if something is impermeable?
It means nothing can get through it. Some things are permeable, meaning that liquids or other matter can "permeate" them or get into them, like a kitchen sponge for instance. Others are impermeable, meaning nothing can get through or into them.
What is permeable pavement?
Permeable means capable of being penetrated, especially by water. A new and improved variety of permeable pavement developed in the U. For minimizing stormwater runoff, permeable interlocking concrete pavements are increasingly popular.
What is a definition of permeable?
Definition of permeable : capable of being permeated : penetrable especially : having pores or openings that permit liquids or gases to pass through a permeable membrane permeable limestone. Synonyms & Antonyms Did you know?
What is permeable rock geography?
Definition: Some rocks have pores in them, which are empty spaces. If these pores are linked, then fluid, like water, can flow through the rock. If fluid can flow through the rock, then the rock is permeable.
What does permeable mean in rocks?
For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.
What is permeable example?
The definition of permeable is a material that allows liquids or gases to pass through. A cloth that liquids can pass right through is an example of something that would be described as permeable.
What rocks are permeable?
Permeable rocks include sandstone and fractured igneous and metamorphic rocks and karst limestone. Impermeable rocks include shales and unfractured igneous and metamorphic rocks.
What are permeable rocks used for?
Chalk is a soft rock and wears away easily. This makes it ideal for making chalk sticks to write on blackboards. Some rocks, such as sandstone or chalk, let water soak through them. They are called permeable rocks.

What objects are permeable?
Permeable Surfaces or Materials Permeable surfaces contain pores or openings that allow liquids and gases to pass through. These surfaces can be penetrated. Some common permeable surfaces are gravel, porous materials and grass.
What is permeable and impermeable?
Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don't allow water to penetrate, forcing it to run off.
What is permeable soil?
The permeability of soil describes how water (or other liquid) and air are able to move through the soil. In the case of rainfall or irrigation, water moves very easily through highly permeable soils and very slowly through soils with low permeability.
What is the meaning of permeable barrier?
A low-permeability barrier used to prevent or reduce the migration of potentially harmful chemicals, or contaminants, into the surrounding environment.
What is not permeable?
Non-Permeable means any surface or material that will not allow the passage of water through that surface or material and into the underlying soil at a rate that ensures run-off will not occur.
What is the difference between permeable and impermeable rock?
Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don't allow water to penetrate, forcing it to run off.
What is an example of a permeable rock quizlet?
Sandstones and conglomerates are porous and permeable.
Why are sedimentary rocks permeable?
Definition: Sedimentary rocks often contain small holes called pores which can contain water or other fluids. If the holes are connected, then the rock is permeable and fluids can flow through the rock.
What are the 3 types of permeability?
There are 3 types of permeability: effective, absolute, and relative permeabilities. Effective permeability is the ability of fluids to pass through pores of rocks or membranes in the presence of other fluids in the medium.
What does "permeable" mean?
per·me·a·ble. (pûr′mē-ə-bəl) adj. Capable of being permeated or penetrated, especially by liquids or gases: permeable membranes; rock that is permeable by water. per′me·a·bly adv. American Heritage® Dictionary of the English Language, Fifth Edition.
What is the adjective for permeable?
adjectivepenetrable, porous, absorbent, spongy, absorptive, perviousmaterials which are permeable to air and water
What does "leaky" mean?
leaky- permitting the unwanted passage of fluids or gases ; "a leaky roof"; "a leaky defense system"
Which has more strength, PTFE or permeable?
The permeablecomposite sheet has two times or more strength, compared to the original porous PTFE sheet.
Do you need planning permission for gravel?
The key is drainage - if you use a porous material, such as gravel, permeableasphalt or permeableblock paving, you won't usually need planning permission.
What is permeable material?
The definition of permeable is a material that allows liquids or gases to pass through. A cloth that liquids can pass right through is an example of something that would be described as permeable. adjective. 10.
Where does the word "permeabile" come from?
From Middle French perméable, from Latin permeabilis.
How deep are confined aquifers?
Known as confined aquifers, they are pools of fresh water trapped in permeable rock strata at depths of 300 to 6,000 feet.
What is the importance of soil permeability?
The permeability of soil formations underlying a waste-disposal site is of great importance with regard to land pollution. The greater the permeability, the greater the risks from land pollution.Soil consists of a mixture of unconsolidated mineral and rock fragments (gravel, sand, silt, and clay)
What is reclamation of swampy land?
reclamation of swampy land. In land reclamation: Reclamation of swampy lands. Of particular importance is the permeability, or ability to transmit water, of the soil and underlying strata. If the soil and underlying strata have a low permeability, a quality frequently found in clay soils, the excess water must be removed by surface flow.
