    摘要: A method and apparatus for directly measuring the hydraulic conductivity of porous materials at various degrees of saturation, the invention involves determination of the rate of rotation under dynamic equilibrium of concentric cylinders having a partially saturated porous material disposed in an annular space between the concentric cylinders, the rate of rotation being directly related to the hydraulic conductivity of the material. The hydraulic conductivity of the material can thus be determined without the need for measuring fluid discharge and piezometric head gradient as is necessary in prior art determination of hydraulic conductivity.
