Hydraulic characteristics and model evaluation for silty sand affected by salt solution concentration

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 ...

Growing Season Precipitation Percolates to Groundwater Past Older Water in Storage Across a Temperate Agricultural Catchment

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

Parameterized Modeling of Unfrozen Water in Frozen Soil Based on the Freezing Characteristics of Multicomponent Cation Solutions and the Electrical Double‐Layer Theory of Clay Colloids

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 ...

Representing air as imaginary water: Analysis of soil water and soil aeration corequisites for plant growth

Vadose Zone Journal, Volume 24, Issue 5, September/October 2025.
Abstract Plant‐available water and adequate soil aeration are two fundamental requirements for successful plant growth. These prerequisites have generally been assessed independently in relation to plant growth, with limited focus on their complementary and competing behavior in a soil–water matrix.

A New Soil-Water Characteristic Curve Model for Unsaturated Loess Based on Wetting-Induced Pore Deformation

Geofluids, 2019
The soil-water characteristic curve (SWCC) is the basis for describing seepage, strength, and constitutive model of unsaturated soil. The existing SWCC models do not work accurately for evaluating loess, because they do not consider the pore deformation ...

Experimental study on improving the water storage capacity of sandy capillary barrier with bio‐based or biomass materials

Vadose Zone Journal, Volume 24, Issue 5, September/October 2025.
Abstract Capillary barrier is an engineered structure composed of a fine‐grained layer overlying a coarse‐grained layer. However, traditional two‐layer configurations of fine and coarse grains exhibit suboptimal water storage performance in semi‐humid to humid regions.

Numerical Investigation of Evaporation‐Driven Salt Uptake in Store‐Release Soil Covers Over Hypersaline Tailings

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Placing moisture store‐release (SR) soil covers over hypersaline tailings has been a promising way to rehabilitate closed tailings storage facilities. However, the performance of SR covers in limiting evaporation‐driven salt migration remains less investigated. A one‐dimensional numerical model that couples the transport of liquid water, water

Excellent AUC for joint fluid cytology in the detection/exclusion of hip and knee prosthetic joint infection

Biomedical Papers, 2017
Background and Aim. The aim of this study was to evaluate the characteristics of synovial fluid (SF) white cell count (SWCC) and neutrophil/lymphocyte percentage in the diagnosis of prosthetic joint infection (PJI) for particular threshold values ...
