A Probabilistic and Mechanical Approach for Hysteresis of SWCC in Unsaturated Soil

Geo-Frontiers 2011, 2011
The relationship between suction and water content in an unsaturated soil is called the soil-water characteristic curve (SWCC). The SWCC of unsaturated soils is hysteretic in nature. In this paper, a numerical model for hysteresis is proposed to simulate the main and scanning curves of the SWCC in an unsaturated soil based on KITA-ARA model and KITA ...

Physical Modeling of SWCC for Granular Materials

2007
A physically model was used in this study to estimate the soil–water characteristic curve (SWCC) of granular materials in case of Hostun sand. Based on soil parameters and pore geometry the main drainage and main imbibition process as well as a scanning drainage and scanning imbibition process was determined.

Experimental Investigation of the Soil-Water Characteristic Curves (SWCC) of Expansive Soil: Effects of Sand Content, Initial Saturation, and Initial Dry Unit Weight

Water (Switzerland)
Soil-water characteristic curve (SWCC) is an essential parameter in unsaturated soil mechanics, and it plays a significant role in geotechnical engineering to enhance theoretical analysis and numerical calculations. This study investigated the effects of

Toyobo and SWCC to pilot test membrane technology

Filtration Industry Analyst, 2019
Japan's Toyobo Co Ltd and Saudi Arabia's Saline Water Conversion Corporation (SWCC) have signed a memorandum of understanding (MoU) on a joint pilot test aimed at realizing the practical application of a new brine concentration (BC) membrane technology that uses concentrated brine discharged by seawater desalination plants.

Modeling SWCC for Coarse-Grained and Fine-Grained Soil

2020
Following Chap. 2, the work is extended to predict SWCC of a soil with different initial densities by using Bayesian method, for both coarse-grained and fine-grained soil. An adjustment parameter (β) is introduced to express the relationships between the matric suctions of two soil samples.

Measurement of SWCC of Xiamen Residual Soil by Filter Paper

Applied Mechanics and Materials, 2012
Soil suction is one of the most important parameters for unsaturated soils. An experimental program was carried out to measure the maric suction of soil specimens of a residual soil in Xiamen by filter paper method. Initial water content, soil structure, and stress state were taken into account to investigate the hysteresis loop of SWCC.

Study of measured and fitted SWCC accounting the irregularity in the measured dataset

International Journal of Geotechnical Engineering, 2016
The relationship between soil suction and water content, popularly known as the soil water characteristic curve (SWCC) provides significant information to evaluate the behaviour of unsaturated soils in engineering practice. For measuring soil suction over the entire range, combination of suction measurements from different instruments is quite common ...

Use of SWCCs to describe the dewatering of product coal

2009
Australian product coals are becoming finer-grained, mainly due to improvements in the performance of ultra-fine coal recovery methods. The finer the product coal size fraction, the more capacity it has to store water during beneficiation and the higher the pressure required to facilitate dewatering to meet the specified moisture. Following the removal
