permeability (soil )
(1) The ease with which gases and liquids penetrate or pass through a bulk mass of soil or a layer of soil. Because different soil horizons vary in permeability, the specific horizon should be designated.

Permeability: The ability of a water bearing material to transmit water. It is measured by the quantity of water passing through a unit cross section, in a unit time, under 100 percent hydraulic gradient.

permeability
Ability or power to enter or pass through a cell membrane.
permeability coefficient,P
Quantity defining the permeability of molecules across a cell membrane and expressed as: ...

Permeability: The rate at which liquids pass through soil or other materials in a specified direction.
Permissible Dose: The dose of a chemical that may be received by an individual without the expectation of a significantly harmful result.

Permeability: Capacity of a rock or soil material to transmit a fluid. DIAGRAM
Piezometric surface: See potentiometric surface. DIAGRAM ...

permeability The ability of a porous medium to transmit fluids under a hydraulic gradient. Highly permeable soils are more likely to result in the leaching of contaminants than soils of lower permeability.
permeability coefficient ...

Permeability. The capability of soil or other geologic formations to transmit water.

Permeability: capacity of soil, sediment, or porous rock to transmit water.

PERMEABILITY
The ability of an aquifer or water bearing formation to allow water to pass through it. Permeability is also known as effective porosity because it is a function of interconnected saturated pore spaces.

permeability : A qualitative description of the relative ease with which rock, soil, or sediment will transmit a fluid (liquid or gas). Often used as a synonym for hydraulic conductivity or coefficient of permeability.

permeability. Generally used to refer to the ability of rock or soil to transmit water.
permeate (PURR-me-ate). To penetrate and pass through, as water penetrates and passes through soil and other porous materials.

Permeability
The ability of a medium to pass a fluid under pressure.

Air Permeability: Permeability of soil with respect to air. Important to the design of soil-gas surveys. Measured in darcys or centimeters-per-second.

Permeability - The property of permitting liquids or gases to pass through. A highly permeable soil, such as sand, allows a liquid to pass through quickly. Clay has a low permeability.

Air Permeability
The degree to which a given material or substance will permit the passage of air. Important to the design of soil-gas surveys. Measured in darcys or centimeters-per-second.

Relative Permeability- The permeability of a rock to gas, NAIL, or water, when any two or more are present.
Relative Risk Assessment- Estimating the risks associated with different stressors or management actions.

Permeable/Permeability: Capable of transmitting water (porous rock, sediment, or soil); the rate at which water moves through rocks or soil.

Permeability - the property or capacity for transmitting a fluid. Permeability is measured as the number of inches per hour
that water moves downward through the saturated soil. Terms describing permeability are: Very slow . = <0.

semi-confined aquifer An aquifer that is partially confined or overlain by a formation of low permeability through which water can pass slowly. Compare confined aquifer, unconfined aquifer.

It is formed from snow after passing through one summer melt season and becomes glacier ice after its permeability to liquid water falls to zero.

1) Aquifer means a subsurface layer or layers of rock or other geological strata of sufficient porosity and permeability to allow either a significant flow of groundwater or the abstraction of significant quantities of groundwater. 2) Layers of rock, ...

Scientists use the term organic to mean those chemical compounds which are based on carbon. Permeability: The property of permitting liquids or gases to pass through. A highly permeable soil, such as sand, allows a liquid to pass through quickly.

Infiltration occurs when the water seeps into the ground, The infiltration rate depends on the permeability of the ground.

The top layer becomes saturated first because it has a higher permeability or infiltration rate. The underlayment cannot allow water to enter it as quickly so that water accumulates in the saturated top layer.

A stratigraphic unit which, because of low permeability relative to the units above or below, prevents or impedes upward or downward movement of water and pressure.
