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.

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.

Physical-statistical model for estimation of hysteresis of soil-water characteristic curve
Yantu gongcheng xuebao, 2023 The hysteresis phenomenon is commonly observed associated with both the soil-water characteristic curve (SWCC) and the hydraulic conductivity function (HCF) of unsaturated soils. In other words, the volumetric water content and the hydraulic conductivity
