Abstract
The values of hydraulic conductivity of some soils may vary by several orders of magnitude within the water content range of interest. Most measurement systems can not efficiently cover such a wide range. The available experimental data cannot represent the complete relationships describing the hydraulic properties. To replace the missing information several methods have been applied to compute the hydraulic properties using either empirical, semi-empirical, or theoretical models. This chapter reviews the various approaches for estimating the K(6), and/or K(yp) relationships and provides guidance for selecting formula or calculation procedure appropriate for the available soil data and characteristics. Gardner determines the values of coefficients of certain formulas for several soil classes. These values may serve as a guideline for rough estimation of hydraulic conductivity when no data are available, but the soil classification is.
