Governing failure mode of unsaturated soil slopes under rainwater infiltration
E3S Web of Conferences, 2016 Due to rainwater infiltration and loss of matric suction above the wetting font, both translational and rotational slips may occur in an unsaturated soil slope. It is useful to know which failure mode is more critical.

New Polymer Tensiometers: Measuring Matric Pressures Down to the Wilting Point [PDF]
, 2007 Tensiometers are commonly used for measuring soil water matric pressures. Unfortunately, the water-filled reservoir of conventional tensiometers limits their applicability to soil water matric pressures above approximately –0.085 MPa. Tensiometers filled

Capillary barrier effect on the response of residual slope to rainfall infiltration [PDF]
, 2008 Rainfall-induced slope failure is a common problem in areas covered by residual soil in tropical countries. The soil exists in unsaturated condition as ground water table is located well below the ground surface.

Effective Stress Concept in Unsaturated Soils: Clarification and Validation of an Unified Framework [PDF]
, 2007 The effective stress principle, conventionally applied in saturated soils, is reviewed for constitutive modelling purposes. The assumptions for the applicability of Terzaghi’s single effective stress are recalled and its advantages are inventoried.
