Soil-Water Characteristic Curve of Residual Soil from a Flysch Rock Mass
Geofluids, 2018 Depending on the nature of the material and suction range, laboratory measurements of the soil-water characteristic curve (SWCC) can be time-consuming and expensive, especially for residual soils, in which a wide range of particle sizes and soil ...

Variability of soil-water characteristic curve [PDF]
, 2019 In recent years, unsaturated soil mechanics as related to soil above ground water table and compacted soil, has received increased attention in geotechnical engineering. The soil-water characteristic curve (SWCC) defines the relationship between the water amount in the soil (i.e. gravimetric water content, w, volumetric water content, w, or the degree

EFFECT OF SAMPLE RE-SATURATION ON SOIL-WATER CHARACTERISTIC CURVE
Revista Caatinga, 2018 Soil-water characteristic curve (SWCC) is an important tool for water management in irrigated agriculture. However, factors such as texture and structure of soils influence SWCC behavior. According to the literature, wetting and drying cycles alter SWCC.

Modeling of transpiration reduction in van Genuchten-Mualem type soils [PDF]
, 2009 We derive an analytic expression for the matric flux potential (M) for van Genuchten-Mualem (VGM) type soils which can also be written in terms of a converging infinite series.

Prediction model for soil-water characteristic curve of loess under porosity change
Yantu gongcheng xuebao, 2022 The loess has obvious macropore structure. The internal pores change continuously in the process of water immersion and collapsibility, resulting in the dynamic change of soil-water characteristic curve in the process of water immersion.
