<p>This paper presents the shear strength study of a saturated and unsaturated lateritic tropical soil, via triaxial compression tests on undisturbed (loose) and compacted soil samples. The shear strength of the soil increases hyperbolically with increasing ...

<p>Rainfall-induced landslides in steep soil slopes of volcanic origin are a major threat to human lives and infrastructure. In the context of constructing early warning systems in regions where extensive data on landslide occurrences and associated rainfall ...

Surficial slope failures are generally induced by the collection of precipitation in the cracks formed during dry summers. In the present research, an earthen dam in North Texas subjected to past failures due to surficial slope failures was selected. Soil ...

<div style="text-align: left;">After a brief review of a number of developments of unsaturated soil mechanics, the paper presents some applications to engineering problems. The first case involves the collapse of a residual soil in <div style="text-align: ...

A new centrifuge permeameter was developed with the specific objective of expediting the measurement of the hydraulic characteristics of unsaturated soils. The development, theoretical basis, and typical results associated with using the centrifuge permeameter ...

This paper presents the hydraulic characteristics of an unsaturated, compacted clay, including its soil-water retention curve SWRC and hydraulic conductivity function K function , determined using a new centrifuge permeameter developed at the University ...

This study includes an experimental investigation of the transient movement of water in unsaturated soil layers underlain by a geocomposite drainage layer (GDL) during cycles of infiltration and evaporation

This paper initially presents the fundamental aspects of evapotranspiration as well as of its evaporation and transpiration components. Typical methods used for prediction of evapotranspiration based on meteorological information are also discussed. The current ...

This paper presents initial laboratory test results which point to the main source of strength in (unstabilised) rammed earth being due to suction, showing that it can be regarded as an unsaturated soil.

<p>The issue of slope stability is an core concern to geotechnical engineers. Traditional methods of analysis assume that the soil is fully saturated. However, throughout much of the world, slopes exist in residual soil deposits. Such soils are often unsaturated, ...
