Porosity: The capacity of soil or rock to hold water. The ratio of the volume of void spaces in a rock or sediment to the total volume of the rock or sediment. DIAGRAM
Potable water: Suitable for human consumption as drinking water.
porosity
The volume percentage of the total bulk not occupied by solid particles.

Porosity: The ratio of the volume of void or air spaces in a rock or sediment to the total volume of the rock or sediment. The capacity of rock or soil to hold water varies with the material.
Porosity: Degree to which soil, gravel, sediment, or rock is permeated with pores or cavities through which water or air can move.
porosity The ratio of the volume of small openings in soil or rock to its total volume, usually expressed as a percentage. Of interest as it determines the capacity of soil or rock to hold water.

POROSITY
The ratio of the volume of voids to the total volume of a rock or unconsolidated material. It is a measure of the amount of empty 'space' in a material. See permeability.

porosity. the capacity of soil of rock to hold water.
positive displacement pump. A type of piston, diaphragm, gear or screw pump that delivers a constant volume with each stroke.
Porosity, Primary: The pore spaces which were created at the time of deposition of a soil or rock unit.
Porosity, Secondary: The pore spaces which were created after the time of deposition of a soil or rock unit (e.g. fractures, solution channels).
Effective porosity: The portion of pore space in saturated permeable material where the movement of water takes place.
Effective Porosity for Flow (ne or nef)
Represents the interconnected porosity of a material. In a porous material, some void spaces may be saturated but are not able to transmit water, and so are not available for flow.
Under moist conditions the soil can be compacted by traffic and the soil porosity can be reduced.
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, ...
osteoporosis
Significant decrease in bone mass with increased porosity and increased tendency to fracture.
ovicide
Substance intended to kill eggs.
The amount of water lost from soil upon drying to a constant weight, expressed as the weight per unit of dry soil or as the volume of water per unit bulk volume of the soil. For a fully saturated medium, moisture content indicates the porosity. 2.
porosity. the amount of space or pores within soil or rock, relative to the total volume of that substance.
