Bayesian estimation of soil-water characteristic curves
Canadian Geotechnical Journal, 2022The soil-water characteristic curve (SWCC) is a significant prerequisite for studying the mechanical properties of unsaturated soil. As experimental measurement of the SWCC is time-consuming, empirical methods have been suggested to estimate the SWCC. However, the uncertainty associated with SWCC can be substantial.

Soil–water characteristic curves of gap-graded soils
Engineering Geology, 2012Abstract Soil–water characteristic curves (SWCCs) of compacted mixtures of residual soil and gravel with different particle sizes were determined from laboratory tests. The study involved compacted mixtures of 50% residual soil by dry mass and 50% gravel of different particle sizes.

An evolutionary approach to modelling the soil–water characteristic curve in unsaturated soils
Computers & Geosciences, 2012In this paper a new approach is presented based on evolutionary polynomial regression (EPR) for modelling of soil-water characteristic curve in unsaturated soils. EPR is an evolutionary data mining technique that generates a transparent and structured representation of the behaviour of a system directly from data.

Nature of Soil–Water Characteristic Curve for Plastic Soils
Journal of Geotechnical and Geoenvironmental Engineering, 2005Determinations of unsaturated soil parameters using experimental procedures are time consuming and difficult. In recent years, the soil–water characteristic curve (SWCC) has become an important tool in the interpretation of the engineering behavior of unsaturated soils.

Soil-Water Characteristic Curves for Compacted Clays
Journal of Geotechnical and Geoenvironmental Engineering, 1997Soil-water characteristic curves (SWCCs) are presented for four compacted clay barrier soils that were prepared at different compaction water contents (dry, wet, and optimum water content) and compactive efforts (standard and modified Proctor). The SWCCs were measured in the laboratory using pressure plate extractors.

Study on the Test of Soil Water Characteristic Curve
Advanced Materials Research, 2011The test of soil water characteristic curve (SWCC) and its mathematic model are present. The SWCC can describe the relationship between unsaturated soil matric suction and water content. Matric suction is an important parameter to address when studying the engineering properties of unsaturated soil.

Predicting Bimodal Soil–Water Characteristic Curves
Journal of Geotechnical and Geoenvironmental Engineering, 2005Failure of colluvial soil deposits induced by rainfall is a common geohazard in the natural terrain. Many colluvial soils are widely and gap graded with a minimal sand fraction. In order to study the pore water pressures in such gap-graded, unsaturated soil deposits through a seepage analysis and to evaluate the stability of these soil deposits, the ...

Probabilistic Analysis of Soil-Water Characteristic Curves
Journal of Geotechnical and Geoenvironmental Engineering, 2010Direct measurement of the soil-water characteristic curve (SWCC) is costly and time consuming. A first-order estimate from statistical generalization of experimental data belonging to soils with similar textural and structural properties is useful.
