Estimation of SWCC and Permeability for Granular Soils
2020This chapter presents a new estimation model for soil–water characteristic curve (SWCC) of granular soils with the effect of initial density. The proposed model, namely the modified Fredlund and Xing (MFX) model, is based on the Fredlund and Xing equation without increasing the number of parameters.

An Oedometer-Type Pressure Plate SWCC Apparatus
Geotechnical Testing Journal, 2008Abstract A new oedometer device for SWCC determination has been evaluated by testing a wide range of soil types, and recommendations for best practices for use of this device have been made. The new device allows application and control of the net normal stress, σ−ua, in addition to the matric suction, ua−uw.

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 New Equation for SWCCs of Unsaturated Soils
2018In the current geotechnical engineering practice, soil-water characteristic curves (SWCCs) are essential for quantifying the mechanical responses of unsaturated soil. The SWCC can be measured from laboratory or estimated from some empirical equations.

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.

Prediction of SWCC using artificial intelligent systems: A comparative study
Scientia Iranica, 2011 AbstractThe significance of the Soil Water Characteristic Curve (SWCC) or soil retention curve in understanding the unsaturated soils behavior such as shear strength, volume change and permeability has resulted in many attempts for its prediction. In this regard, the authors had previously developed two models, namely.

Physical Modeling of SWCC for Granular Materials
2007A 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.

Materials performance and failure evaluation in SWCC MSF plants
Desalination, 1994Abstract An MSF plant is subjected to different forms of deteriorations due to the use of a wide variety of materials and existence of diverse types of environments. It is well established that seawater and uncondensed gases are responsible for the majority of the failures reported in desalination plants.
