Further examination of the use of the equivalent salt solutions method for predicting hydraulic conductivity of soils for different salt solutions

Abstract

Hydraulic conductivities of Pachappa and Waukena soils for different salt solutions, predicted by the equivalent salt solution methods, showed satisfactory agreement with measured values. The values of equivalent salt solutions for these soils were calculated from macroscopic swelling values of extracted clays. The equivalent salt solution method and the simplified domain model method of McNeal predicted equally accurately, the changes in hydraulic conductivities of Pachappa soil in salt solutions with sodium absorption ratio values from 15 to 100.
