Effects of aggregate size on water retention capacity and microstructure of lime-treated silty soil [PDF]
, 2015 International audienceLime treatment is a common technique of improving the workability and geotechnical properties of soils. In this study, the aggregate size effects on the water retention capacity and microstructure of lime-treated soil were ...

A novel approach to determining the contribution of the fiber and fines fraction to the water retention value (WRV) of chemical and mechanical pulps [PDF]
Cellulose, 2017 The swelling behavior of pulp fibers has a significant influence on process and product properties. The water uptake of fibers is controlled by a different mechanism. While fiber charge is a driving factor for swelling, the swelling is hindered by the solid structure of the fiber wall.

Soil Water Retention and Relative Permeability for Conditions from Oven‐Dry to Full Saturation
Vadose Zone Journal, 2011 Common conceptual models for unsaturated flow assume that the matric potential is attributed to the capillary force only. These models are successful at high and medium water contents but often give poor results at low water contents.

Prediction of the absolute hydraulic conductivity function from soil water retention data
Hydrology and Earth System Sciences, 2023 . For modeling flow and transport processes in the soil–plant–atmosphere system, knowledge of the unsaturated hydraulic properties in functional form is mandatory. While much data are available for the water retention function, the hydraulic conductivity

A water retention model accounting for void ratio changes in double porosity clays
Acta Geotechnica, 2021 This paper presents a constitutive model that predicts the water retention behaviour of compacted clays with evolving bimodal pore size distributions. In line with previous research, the model differentiates between the water present inside the saturated
