However, there is also a concept of closed porosity and effective porosity, i . e ., the pore space accessible to flow.
42.
As the fault begins to slip, this rapid increase in temperature close to the fault causes the water in the pore space to vaporize.
43.
"Porosity : " \ phi The percentage of a given volume of rock that is pore space and can therefore contain fluids.
44.
When a layer of sediment is originally deposited, it contains an open framework of particles with the pore space being usually filled with water.
45.
"' Soil structure "'describes the arrangement of the solid parts of the soil and of the pore space located between them.
46.
This slippage is increased in heavy rainfall areas and in shallow soils; deep soils have more total pore space and are not as prone to slippage.
47.
Anthracite has a history of use in blast furnaces for iron smelting; however, it lacked the pore space of metallurgical coke, which eventually replaced anthracite.
48.
The CAWST Version 10 biosand filter takes this into account; the volume of the water reservoir is equal to the pore space volume of the sand layer.
49.
The membrane seal will leak whenever the pressure differential across the seal exceeds the threshold displacement pressure, allowing fluids to migrate through the pore spaces in the seal.
50.
Stygofauna can live within freshwater aquifers and within the pore spaces of limestone, calcrete or laterite, whilst larger animals can be found in cave waters and wells.
