Role of Bimodal Water Retention Curve on the Unsaturated Shear Strength

open access: yesApplied Sciences, 2022
Changes in climatic conditions are expected globally resulting in a higher rainfall intensity and longer duration of rainfall. The increase in the rainwater infiltration into the soil contributes to many geotechnical issues, such as excessive settlement,

Water retention curve for hydrate‐bearing sediments [PDF]

open access: yesGeophysical Research Letters, 2013
AbstractThe water retention curve plays a central role in numerical algorithms that model hydrate dissociation in sediments. The determination of the water retention curve for hydrate‐bearing sediments faces experimental difficulties, and most studies assume constant water retention curves regardless of hydrate saturation.

Pedotransfer functions for point and parametric estimations of soil water retention curve

open access: yesPlant, Soil and Environment, 2006
A water retention curve is required for the simulation studies of water and solute transport in unsaturated or vadose zone. Unlike the direct measurement of water retention data, pedotransfer functions (PTFs) have attracted the attention of researchers ...

Soil Water Retention Curve as Affected by Sample Height

open access: yesRevista Brasileira de Ciência do Solo, 2018
: The soil water retention curve is one of the main instruments to assess the soil physical quality and to improve soil management. Traditionally, the equipment most used in the laboratory to determine the retention curve has been Haines funnels and ...

RETENTION CURVES AND AVAILABLE WATER CAPACITY IN LATOSOLS [PDF]

open access: yesEngenharia Agrícola, 2018
ABSTRACT Water stored in the soil between field capacity and the permanent wilting point, is known as the available water capacity. Its availability to be effectively used by plants depends on the type of soil and its water retention characteristics.

Temperature Dependence of Water Retention Curves for Wettable and Water-Repellent Soils

open access: yesSoil Science Society of America Journal, 2002
The capillary pressure (ψ) in unsaturated porous media is known to be a function of temperature ( T ). Temperature affects the surface tension (σ) of the pore water, but possibly also the angle of contact (γ).

Modelling soil water retention to identify management influence on soil pore characteristics

open access: yesAnais da Academia Brasileira de Ciências, 2022
The water retention curve is widely used in studies involving soil. The management systems directly influence soil structure by altering water retention dynamics.

Evolution of the soil water retention curve based on plastic volumetric strain [PDF]

open access: yesE3S Web of Conferences, 2020
The water retention behaviour of soil can be defined as the relationship between the degree of saturation (or water content) and suction at a constant temperature, which characterises the hydraulic behaviour of unsaturated soils, normally represented as ...

Water Retention Characteristics of Various Sizes of Expanded Perlite Produced from Two Different Types of Rocks

open access: yesHorticulturae, 2022
This study presents the results of the water retention characteristics of six groups (0.25 mm to 8.35 mm) of expanded perlite (EP) produced from two crushed raw perlite rocks of Turkey (A) and China (B).
