Soil-water characteristic curve considering temperature and void ratio under capillarity and adsorption

Yantu gongcheng xuebao
The soil-water characteristic curve (SWCC) is an important constitutive relationship of unsaturated soils. The temperature and void ratio obviously affect the SWCC of soils.

Ensemble learning of soil–water characteristic curve for unsaturated seepage using physics-informed neural networks

Soils and Foundations
The determination of the soil–water characteristic curve (SWCC) is crucial for hydro-mechanical modelling and analysis of soil slopes. Conventional inverse analysis often relies on a predetermined SWCC model for parameter estimation.

Study on the Effect of Soil Type and Salinity on Water–Soil Characteristic Curves of Saline Soils Based on the Vapor Balance Technique

Advances in Civil Engineering
The soil–water characteristic curve (SWCC) describes the relationship between water content and soil suction, which is an important tool for determining the engineering properties of unsaturated soil. By measuring SWCC through vapor equilibrium technique,

RELAIBILITY ASSESSMENT OF THE SOIL-WATER-RETENTION FOR UNSATURATED SAND SOILS

Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ
In this investigation, the soil-water-retention is described in the soil-water-characteristics-curve (SWCC). SWCC contains the data required to explain the unsaturated soils' mechanical behavior.
