Determination of Hydraulic Conductivity from Complete Grain‐Size Distribution Curves

Abstract Current methods of relating hydraulic conductivity to grain‐size distribution rely on a single so‐called representative grain‐size distribution parameter such as the effective diameter, geometric mean, median, standard deviation, etc. An alternative procedure is proposed which relates the hydraulic conductivity to the initial slope and intercept of the grain‐size distribution curve. The proposed methodology is documented with data from Australia and Saudi Arabia.
