Abstract

This research proposed to analyze the dependence on the water retention properties in granular samples (Guamo sand) regarding diferent contents of fnes (kaolin). The extended evaporation method (EEM) and dew point method (DPM) allowed
the construction of the water retention curves (WRCs). These methods can determine the matric suction of the samples at
volumetric water contents in the partially saturated state. The results revealed that the Guamo sand only showed signifcant
suction values in the pendular state of the system. As the kaolin content in the samples increased, the desaturation process
revealing high suction values, even when samples have up to 30% volumetric water content. The evaluation of the experimental methods was generated from a WRC setting using traditional constitutive models. The prediction capacity of each
model is defned with the coefcient of determination, where the behavior of the data indicates more signifcant predictive
potential in high suction ranges.
