Closed-Form Functions for the Soil Water-Retention Curve of Sand Fractions and Sand Mixtures

Publication: Unsaturated Soils 2006

Abstract

Four closed-form water-retention curve functions were validated using the previously measured water retention curve of 4 sand fractions and their 6 two-component mixtures. Out of the models of Gardner (1958), Fredlund - Xing (1994) and the simplified and non-simplified models of Van Genuchten (1980), the non-simplified model of Van Genuchten model fitted with the smallest error to the tested soils.
