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 ...

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 ...

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,

Characterization of the water retention curves of Everglades wetland soils
Geoderma, 2021Abstract Alterations to the natural hydrology of wetlands like the Everglades have increased the presence of unsaturated zones in typically inundated soil environments. Understanding soil moisture dynamics through numerical modeling requires a large dataset of soil hydraulic parameters (SHPs) due to the spatially variable nature of hydromorphic soils

Temperature Dependence of Soil Water Retention Curves
Soil Science Society of America Journal, 1986Abstract Effects of entrapped air volume and surface tension of soil solution are often regarded as the primary cause of temperature effects on the water retention curve. A procedure was developed to determine simultaneously the water characteristic curves and the volume of entrapped air for a glass beads medium and a Norfolk sandy ...

A conceptual model of the soil water retention curve
Water Resources Research, 1998A conceptual model based on the assumption that soil structure evolves from a uniform random fragmentation process is proposed to define the water retention function. The fragmentation process determines the particle size distribution of the soil. The transformation of particles volumes into pore volumes via a power function and the adoption of the ...

A Technique for Producing Soil Water Retention Curves
South African Forestry Journal, 1990SYNOPSIS Water retention curves compiled for specific soil types are an essential management and research tool in evaluating plant stress. The method of producing water retention curves by means of the 1500 kPa pressure extractor is described.
