A NEW EQUATION FOR SIMULATING SOIL WATER CHARACTERISTIC CURVE [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2007 Several mathematical equations have been proposed to simulate soil water characteristic curve (SWCC). All the equations show reasonable fit with measured data through a specified range of suction and in a specific soil texture, but this is not the case

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.Soil–water retention characteristics and plant‐available water (PAW) are critical for irrigation management in semiarid Andosols. This study determined the soil–water characteristic curves (SWCCs) of Andosols at the Melkassa Agricultural Research Center (MARC), Central Rift Valley (CRV), Ethiopia, using a pressure plate apparatus at matric potentials ...

A novel liquid bridge model for estimating SWCC and permeability of granular material
, 2015 As traditional liquid bridge model based on Yang-Laplace theory fails to model behaviors of unsaturated granular materials when liquid bridges fuse with each other in funicular and capillary regimes, a method called "Redistribution of Air Volume and ...

Comparative analysis of four soil water sensors for irrigation water management
Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.Abstract With the increasing availability of soil water sensing technologies for irrigation management, it is essential to compare sensor options in production field settings. In this study, four soil water sensors—CropX, FieldNet with Watermark sensors, Valley Aqua Trac Lite using Sentek probe, and Aqua Trac Pro with Watermark sensors—were compared ...

Vadose Zone Journal, Volume 24, Issue 6, November/December 2025.Abstract The hydraulic properties of silty sand are affected by a combination of internal and external factors such as the compaction, moisture content, and groundwater properties. This study investigated the measurement methods and hydraulic characteristics of unsaturated silty sand.

Evaporation‐induced salt precipitation and feedback on water–heat transport in saline soil
Vadose Zone Journal, Volume 24, Issue 6, November/December 2025.Abstract The precipitation and growth of salt crystals significantly affect soil water and heat balance. However, the effects of salt precipitation on water–heat flow in unsaturated soil remain unclear. Therefore, we investigated the influence mechanisms of salt precipitation on water and heat transport in saline sandy soil by conducting controlled ...

Water Resources Research, Volume 61, Issue 10, October 2025.Abstract How water is stored within‐ and released from‐the vadose zone controls groundwater recharge, plant water uptake, and the movement of dissolved solutes (nutrients, carbon, pollutants). The goal of this study was to determine the age of water recharging groundwater during the growing season in a temperate agricultural catchment. We measured soil

Water Resources Research, Volume 61, Issue 10, October 2025.Abstract Soil freezing characteristics are predominantly governed by the mechanism of bound water, which essentially constitutes a multicomponent cations distribution within the electrical double‐layer (EDL) on clay particles. The freezing behavior of bound water is determined by two critical factors: (a) the distribution characteristics of cation ...
