Review of soil-water characteristic curve equations
TL;DR: In this article, the authors evaluate the more popular unsaturated soil mechanics equations and show that all the equations can be derived from a single generic form, which performs very well for all soil types.

TL;DR: In this paper, the relative importance of soil properties, rainfall intensity, initial water table location and slope geometry in inducing instability of a homogenous soil slope under different rainfall was investigated through a series of parametric studies.

Controlling parameters for rainfall-induced landslides
TL;DR: In this paper, the authors identify the influence of some of those parameters on the stability of an unsaturated soil slope during rainfall and show that the ratio between the saturated coefficient of permeability with respect to water and the rainfall patterns can significantly influence the seepage pattern within an uns saturated soil slope.

Determination of the shear strength parameters of an unsaturated soil using the direct shear test
TL;DR: In this article, a multistage direct shear test was performed on saturated and unsaturated specimens of a compacted glacial till and the results showed that the axis-trajectory shear was effective on both unsaturated and saturated specimens.

Permeability functions for unsaturated soils
TL;DR: It is shown that it is possible to degenerate statistical models to macroscopic models and then to empirical models, and a new empirical equation for the permeability function is suggested.
