Abstract: A laboratory index defined as gravimetric water content at ambient relative humidity of 75%

Abstract: A complete understanding of soil–water interactions and the corresponding mechanical behavior of unsaturated soils requires differentiating adsorptive and capillary components of water retention and dominant water uptake ...

Abstract: Alternative laboratory approaches for cyclic permeation-desiccation experiments on geosynthetic clay liner (GCL) specimens are compared. Permeation cycles for hydraulic conductivity (k) are conducted in flexible-wall ...

Abstract: The concept of the suction stress characteristic curve (SSCC) for unsaturated soil is presented. Particle-scale equilibrium analyses are employed to distinguish three types of interparticle forces: (1) active forces ...

Abstract: The engineering concepts necessary for fully describing contaminant transport processes in soil and groundwater have been largely neglected by traditional civil engineering curricula in the United States. New lecture and ...

Abstract: Constitutive relationships among water content, matric suction, and capillary stress in unsaturated granular soils are modeled using a theoretical approach based on the changing geometry of interparticle pore water menisci. ...

Abstract: Short-ranged hydration of water on mineral surfaces and capillary condensation in larger pores influences mechanical behavior of unsaturated soil (e.g., strength, stiffness) in different ways. Transition between water ...

Abstract: Despite increasing awareness that cavitation can be a potential mechanism for drainage of water from soil, comprehensive understanding of its effects on soil water retention (SWR) remains largely elusive. A major obstacle ...
