1. Saturated hydraulic conductivity measures soil permeability when the soil is saturated. 2. The hydraulic conductivity of aquifers is often anisotropic for the same reason. 3. There is a clear proportionality between pore throat radii and hydraulic conductivity . 4. It is derived from the saturated hydraulic conductivity of the limiting layer. 5. Aquitards comprise layers of either clay or non-porous rock with low hydraulic conductivity . 6. The recovery rate of moisture deficit during dry periods is empirically related to the hydraulic conductivity . 7. This has a significant effect on the overall hydraulic conductivities ( water permeabilities ) and molecular diffusion coefficients. 8. It is necessary to have a higher porosity in the subsoil in order to improve the hydraulic conductivity . 9. The highest hydraulic conductivity and transmissivity are near the junction of the Xerias and the Eurotas south of Sparti. 10. If the proportionality between pore throat radii and porosity exists then a proportionality between porosity and hydraulic conductivity may exist.
