Advances in Civil Engineering, 2021 The soil-water characteristic curve (SWCC) is an important hydraulic parameter for modeling water flow and contaminant transport in the unsaturated soil. However, direct measurement of the SWCC is still difficult.

Closed-Form SWCC Functions for Granular Mixtures [PDF]
E3S Web of ConferencesFour closed-form water-retention functions (the Gardner, Fredlund – Xing, van Genuchten 4 and 5) were validated using the experimental, ideal water retention curve data of 7 granular fractions (fine gravel, sand and silt) and their 21 mixtures with fractal distribution (being similar to the Fuller curves), composed from 2 to 7 ...

Stress-Dependent Soil Water Characteristic Curves of Compacted Sand–Gypsum Mixtures
Journal of EngineeringThe presence of calcium sulfate (CaSO4) impacts soil structure, bonding, pore size distribution, and water-holding characteristics, altering both compaction characteristics and soil water characteristic curves (SWCC).

Impact of SWCC Measurement Methods on the Numerical Investigations of Unsaturated Soils
Journal of Applied Engineering and Technological Science (JAETS)The soil-water characteristic curve SWCC, also known as the soil-water retention curve SWRC, describes the relationship between soil suction and water content in unsaturated soils. Many studies rely on specific laboratory testing methods without considering their impact on numerical simulations.

A simple approach for predicting soil water characteristic curve of clayey soils using pore size distribution data [PDF]
MATEC Web of Conferences, 2021 The soil water characteristic curve (SWCC) of soils can be derived from the measured pore size distribution (PSD) data by applying capillary models. This method is limited for clayey soils due to the PSD changes during SWCC testing.

Field monitoring and model predicted water balance of monolithic cover [PDF]
MATEC Web of Conferences, 2021 The use of the evapotranspiration cover for landfill is increasing because of its long-term enhanced performance. However, the performance of evapotranspiration cover primarily depends on the onsite geo-climatic conditions.

Fractal model for bimodal soil-water characteristic curve and its application in pore classification
Yantu gongcheng xuebao, 2022 Most existing bimodal soil-water characteristic curve (SWCC) models are derived from the empirical models for unimodal SWCC, in which the parameters have no clear physical meanings or value ranges generally.

Variability of Bimodal Soil-Water Characteristic Curves under Different Confining Pressures
Applied and Environmental Soil Science, 2021 Soils with two subcurves of Soil-Water Characteristic Curve (SWCC) (dual porosity soils) might be found within various residual soils. Soils located in different depths have different confining pressure.

One-stage Bayesian experimental design optimization for measuring soil-water characteristic curve
Yantu gongcheng xuebao, 2023 The direct measurements of soil-water characteristic curve (SWCC) are often costly and time-consuming. Therefore, only a limited number of test data can be obtained from a single SWCC test, based on which the estimated SWCC inevitably produces ...
