Evaluation of Soil-Water Characteristic Curve and Pore-Size Distribution of Fine-Grained Soils

Water, 2022
A soil’s physical properties, mineral types, and pore structure significantly influence the shape and properties of the soil-water characteristic curve (SWCC). This study investigated the effects of the soil’s physical properties and mineral types on the

A NEW EQUATION FOR SIMULATING SOIL WATER CHARACTERISTIC CURVE [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2007
Several mathematical equations have been proposed to simulate soil water characteristic curve (SWCC).   All the equations show reasonable fit with measured data through a specified range of suction and in a specific soil texture, but this is not the case
