A fractal analysis of the water retention curve
Hydrological Processes, 2018AbstractThe dependence of the soil water content ϑ upon the matric potential ψ is studied within a fractal approach that regards the water retention curve as a sequence of well defined fractal regimes. Each of such regimes accounts for a given functional dependence ϑ≡ϑ(ψ), which in turn is characterized by a fractal dimension.

Uncertainties in Water Retention Curve of Bentonite
2020Bentonites are increasingly used for various geoenvironmental applications (e.g. hydraulic barriers and waste containment) owing to its low hydraulic conductivity and high water retention capacity. Investigating the aforementioned problems necessitates the knowledge of the water retention curve (WRC) of bentonite, which maps the variation of the degree

Soil/water retention curve (SWRC) is the relationship between soil/water matric potential and volumetric soil-water content at equilibrium above the reference (zero) level represented by the free water table at atmospheric pressure. SWRC is the basic soil characteristic needed as input data for simulation models. SWRCs have a hysteresis-like character,

Hysteresis of Water Retention Curve of Saline Soil
Unsaturated Soils 2006, 2006The soil water retention curve of a soil is usually not unique. It depends on the soil water flow process. Fully primary curves for draining and wetting processes are necessary in soil water flow modeling. Usually, the primary draining curve can be produced from an experiment with a hanging column apparatus together with a pressure plate apparatus ...

Closing the Loop of the Soil Water Retention Curve
Journal of Geotechnical and Geoenvironmental Engineering, 2015AbstractThe authors, to their knowledge for the first time, produced two complete principal soil water retention curves (SWRCs) under both positive and negative matric suction regimes. An innovative testing technique combining the transient water release and imbibition method (TRIM) and constant flow method (CFM) was used to identify the principal ...

Revisiting laboratory methods for measuring soil water retention curves
Soil Science Society of America Journal, 2023Abstract Traditional laboratory methods for measuring soil water retention curves (SWRCs) typically consist of suction tables, pressure cells, and pressure plate apparatus (i.e., traditional methods). However, technological advancement has resulted in newer methods based on precision mini‐tensiometers and dew ...

Estimation of the water retention curve for unsaturated clay
Canadian Journal of Soil Science, 2011Mir Mohammad Hosseini, S. M., Ganjian, N. and Pashang Pisheh, Y. 2011. Estimation of the water retention curve for unsaturated clay. Can. J. Soil Sci. 91: 543–549. Extensive laboratory tests are essential in order to determine the soil water retention curve, defined as the relationship between water content and suction, in an unsaturated soil.

A new equation for the soil water retention curve
European Journal of Soil Science, 2014Summary The soil water retention curve is a fundamental characteristic of unsaturated zone flow and transport properties. Recent studies show that an air‐entry value is needed in a soil water retention equation in order to provide a better prediction of relative hydraulic conductivity. A new equation considering the air‐entry value is

Water retention curves of multicomponent mixtures of spherical particles
Powder Technology, 2017Abstract The water retention curve (WRC) is a key material function to define the unsaturated behaviour of natural and artificial particulate media. In many circumstances, it is necessary to have the estimate of the WRC in the early stage of a project or a research activity.
