In engineering soil mechanics, it is very common to determine stress–strain relationship of soils (under equiTilled agricultural soils are in a constant state of change induced librium conditions) empirically from simultaneous meaby variations in soil strength due to wetting and drying and compaction by farm implements. Changes in soil structure affect many hydraulic surements of stress and str...

Extreme rainfall events are the major driver of shallow landslide occurrences in mountainous and steep terrain regions around the world. Subsurface hydrology has a dominant role on the initiation of rainfall-induced shallow landslides, since changes in the soil water content affect significantly the soil shear strength. Rainfall infiltration produces an increase of soil water potential, which i...
