Stability Analysis of Multilevel Cutting Slope Before and After Highway Expansion Under Rainfall Conditions

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
This study employs the FLAC3D numerical simulation software to systematically analyze the stability of multitier embankment slopes in the G4 Beijing–Hong Kong–Macau Expressway expansion project, under various rainfall conditions in Hunan Province. The research innovatively compares slope designs before and after the highway expansion, as well as the ...

Comparative analysis of four soil water sensors for irrigation water management

open access: yesAgrosystems, 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 ...

Indirect models for SWCC parameters: reducing prediction uncertainty with machine learning [PDF]

open access: yes
The soil–water characteristic curve (SWCC) is crucial for modelling the transport of water and hazardous materials in the vadose zone. However, measuring SWCC is often cumbersome and time-consuming. This paper introduces indirect models that predict SWCC

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

open access: yesGeofluids, 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 ...

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

open access: yesVadose 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.

Software cloud counting (SWCC) in NGC 224 distance estimation,I

open access: yes, 1998
About 41770 dark clouds were identified through a C++ program [ software cloud counting, SWCC] developed to study the dust content in NGC 224 (M31). The clouds were sorted out according to their opacities and then their areas.

Evaporation‐induced salt precipitation and feedback on water–heat transport in saline soil

open access: yesVadose 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

open access: yesWater 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
