Hydraulic conductivity versus permeability
Web14 mrt. 2024 · Permeability is the hydraulic conductivity, or the rate of flow of the water as it passes through a geotextile, expressed as a velocity, i.e. meters per second. The … WebPermeability is a function of only the flow path geometry. So, if a material has large pores between particles, it means its permeability is high. On the other hand, hydraulic …
