Measurement of SWCC of Xiamen Residual Soil by Filter Paper
Applied Mechanics and Materials, 2012Soil 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.

Effect of Drying and Wetting SWCCs on Unsaturated Soil Slopes
2021The soil water characteristic curve (SWCC) exhibits hysteresis. It is the relation between soil water and soil suction. Desorption (drying) and sorption (wetting) can be used to obtain SWCC. The suction is different in drying and wetting SWCC paths. The slope failures generally take place in wetting SWCC. Therefore, a few efforts have been made in this

A Probabilistic and Mechanical Approach for Hysteresis of SWCC in Unsaturated Soil
Geo-Frontiers 2011, 2011The 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 ...

Toyobo and SWCC to pilot test membrane technology
Filtration Industry Analyst, 2019Japan'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
2020Following 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.

Effect of High Suction Measurement Technique on the SWCC of Expansive Soil
2021The determination of soil water characteristics curve (SWCC) for any particular soil is very essential to understand the suction variation or negative pore water changes with drying or wetting and to obtain the unsaturated soil property functions accurately.

Experimental Study on the SWCC Transition Zone Features of Unsaturated Soil
Indian Geotechnical Journal, 2019In order to study the soils SWCC transition zone features under different steady-state and transient conditions, a series of pressure plate and model tests were carried out; the internal structure adjustment of soil caused by different test conditions is the underlying reason for the change in SWCC transition zone curve.

Use of SWCCs to describe the dewatering of product coal
2009Australian 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
