Calculation of Hydraulic Conductivity: A further Evaluation of some Predictive Methods

Abstract

Abstract A computational method based on the pore‐interaction model of Marshall was shown to compare favorably with modified methods of Millington and Quirk and of Marshall for prediction of hydraulic conductivity vs. water content on a number of soils and a glass bead system. All methods required matching one point on the calculated hydraulic conductivity curve to an experimentally measured hydraulic conductivity value. The calculation methods adequately predicted the experimentally measured values and provide satisfactory conductivity data for many applications. An advantage of the proposed method is its independence of the value chosen for the exponent on the porosity term in the prediction equation.
