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 ...

The Effect of Temperature on the SWCC and Estimation of the SWCC from Moisture Profile under a Controlled Thermal Gradient

2014
In many situations, the upper layers of soil above the ground water table are in a state of unsaturated condition. Although unsaturated soils are found throughout the world, they are predominant in arid or semi-arid regions. In these areas, the soil water characteristic curve (SWCC) which relates the water content to the matric suction could be used as

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 ...

A BP neural network model for SWCC considering consolidation stress

2010 IEEE International Conference on Intelligent Computing and Intelligent Systems, 2010
Soil-Water Characteristic Curve (SWCC) plays an important role in theoretical research and practical application. At present, SWCC can be obtained from experiments. The experimental results are inconvenient for practical application. Some models are presented to fit experimental results, such as Gardner model, V-G model, etc.

Laboratory versus field SWCC data

2009
Soil Water Characteristic Curves (SWCCs) are typically determined in the laboratory by performing drying tests on samples in a Tempe cell. In some cases, re-wetting is also carried out. The advantage of using drying tests is that they are carried out from the saturated state at a given sample test density, so that there is some chance of obtaining ...
