![]() Based on these observations, the relationship of the specific discharge to measurable characteristics of the porous media and were noted as shown in Equations 27, 28, and 29.ĭiameter of uniform glass beads comprising the porous medium (L) A number of columns filled with different sizes of glass beads were set up as Darcy columns and changes in specific discharge were observed. Intrinsic Permeabilityįreeze and Cherry (1979) describe the results of hydraulic conductivity experiments used to explore the relationship between physical properties of the porous media and the fluid. These conditions are also referred to as permeable or of low permeability, respectively. If water easily passes through a porous material it is described as having a high hydraulic conductivity if water is poorly transmitted through a material it has a low hydraulic conductivity. ![]() However, K is not a velocity, rather it represents the transmission properties of the porous material. Thus, the constant of proportionality, K, has units of velocity (e.g., meters/seconds, meters/day). In this configuration, it becomes clear that the units of K are L/T because Q units are (L 3/T), A units (L 2), h units are (L), and L units are (L). Rearranging Darcy’s law to solve for hydraulic conductivity generates Equation 25. It has direction and magnitude and is represented as a vector however, the first part of this discussion presents it as a scalar value. Reynolds number for clean cold water flow.The hydraulic conductivity proportionality constant, K, can be conceptualized as the relative ease of fluid passage through a porous material.
