Webmatrix void ratio and clay type; and, in clast dominated soils, the intergranular void ratio and particle size distribution. The transition from a matrix dominated soil to a clast dominated soil occurs at a fines content between 20% and 35% KEYWORDS: composite soils, hydraulic conductivity, matrix void ratio, intergranular void ratio 1 ... WebThe unit of cm/s is more commonly used in soil mechanics (e.g., the hydraulic conductivity of clay liners in landfills is commonly expressed in cm/s). From the above example, one can tell that a geologic formation with an intrinsic permeability of 1 darcy has a hydraulic conductivity of approximately 10~ 3 cm/s or 20 gpd/ft 2 for transmitting pure water at 20°C.
