The coefficient of permeability varies with the void ratio as e/sup>/(1+e). For a given soil, the greater the void ratio, the higher the value of the coefficient of permeability. Here 'e' is the void ratio. Based on other concepts it has been established that the permeability of a soil varies as e 2 or e 3 /(1+e). Whatever may be the exact ...
Relative permeability, , for phase is then defined from =, as = / where is the permeability of the porous medium in single-phase flow, i.e., the absolute ...
Soil texture determines total volume of the smallest pores; [56] clay soils have smaller pores, but more total pore space than sands, [57] despite a much lower permeability. [58] Soil structure has a strong influence on the larger pores that affect soil aeration, water infiltration and drainage. [59]
h' is the average depth of the water level in the hole relative to the water table in the soil (cm), found as ′ = + D is the depth of the bottom of the hole relative to the water table in the soil (cm). Cumulative frequency distribution of hydraulic conductivity (X-data)
The Plasticity Index of a particular soil specimen is defined as the difference between the Liquid Limit and the Plastic Limit of the specimen; it is an indicator of how much water the soil particles in the specimen can absorb, and correlates with many engineering properties like permeability, compressibility, shear strength and others ...
LNAPL transmissivity is the discharge of light non-aqueous phase liquid (LNAPL) through a unit width of aquifer for a unit gradient.. Scholars Alex Mayer and S. Majid Hassanizadeh define LNAPL transmissivity as the "product of the porous medium permeability and the LNAPL relative permeability, which in turn is a function of saturation, and the thickness of the LNAPL".
