Abstract: A new approach is proposed for modeling thermal conductivity dryout curves (TCDCs) using measurements of soil-water characteristic curves (SWCCs) for coarse-grained unsaturated soils. The approach is based on observation ...

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: A model for the water retention behavior of unsaturated granular soil is developed by extending the classic bundled cylindrical capillary representation of pore space to a geometry more closely approximating that of granular ...

Abstract: An approach is presented for predicting saturated hydraulic conductivity (

Abstract: Laboratory fall cone penetration is measured as a function of saturation for four sands using equipment more commonly used to quantify plasticity and undrained strength of fine-grained soils. Relations between penetration ...

Abstract: Water-retention data for a suite of predominantly sandy soils were analyzed to quantify the effects of two constraints commonly applied to the three-parameter model for the soil-water characteristic curve (SWCC). Systematic ...

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 ...
