MODELS OF SOIL WATER CHARACTERISTICS CURVES: A REVIEW
Soil water characteristic curve (SWCC) is very important in the study of unsaturated soil because it represents a soil’s ability to store and release water as it is subjected to various soil suctions. This storage of moisture in soil is paramount in irrigation engineering, as it determines the irrigation scheduling in dryland.

Hysteresis model for soil-water characteristic curve under dynamic conditions
The soil-water characteristic curve (SWCC) is essential to describe the behavior of unsaturated soils. The capillary hysteresis is an important effect that should be accounted in the equations for SWCC.

Soil water characteristic curve parameters of collapsible sand in Lambayeque, Peru [PDF]
Several structures are built on collapsible soils in the mining and petroleum industries and on civil sites. In order to analyze the stability of such structures, one must properly study the unsaturated soil behavior.
