Imaging and characterization of the preferential flow process in agricultural land by using electrical resistivity tomography and dual-porosity model

Ecological Indicators, 2022
Preferential flow is an important hydrological process, but the complexity of preferential flow channels and great difficulty in determining model parameters present certain challenges for its description on the field. The existing methods for parameters

Thermodynamic Controls on the Competition Between CO2 Solute Transport and Retention in Fracture‐Pore Media: Insights From Real‐Basalt Microfluidics

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Reactive‐surface exposure during basalt carbonation is controlled by the entry and retention of fracture‐transported CO2 solute within adjacent pores, yet these pore‐scale processes remain poorly constrained under reservoir temperature and pressure.

Estimating Parameters of Van Genuchten Model for Soil Water Retention Curve by Intelligent Algorithms [PDF]

Applied Mathematics & Information Sciences, 2013
An improved particle swarm optimization (IPSO) was proposed and the intelligent algorithms such as IPSO, genetic algorithm (GA), and simulated annealing algorithm (SA) were introduced to determine parameters of Van Genuchten (VG) model for soil water retention curve (SWRC) of four typical agricultural soil te xtures (clay, clay loam, silt loam and sand

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 460-478, August 2026.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Virtual Soil Simulator—Finite Volume Method Implementation for the Unsaturated Porous Media Water Transport Model Including Film Flow and Isothermal Vapor Transport Phenomena

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Modeling unsaturated water transport in porous media traditionally relies on the Richards equation (RE) with hydraulic conductivity formulations to consider only capillary liquid water flow. However, this simplification neglects thin water films adsorbed onto particle surfaces, which can contribute significantly to flow under medium to dry ...

Abiotic Iron Precipitation and Its Influence on Groundwater Flow in Subterranean Estuaries Under Tidal Forcing

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Within subterranean estuaries (STEs), Fe2+ from freshwater is oxidized by O2(aq) from seawater to form Fe precipitates and low‐permeability zones (“Fe curtains”). Tidal fluctuations generate an upper saline plume (USP) above the saltwater wedge (SW), enhancing freshwater–seawater mixing and associated chemical reactions.

A comprehensive analytical and computational assessment of soil water characteristics curves in Atlantic Canada: Application of a novel SelectKbestbased GEP model

Agricultural Water Management
For sustainable agriculture, irrigation is one of the most important management practices in a semi-arid climate. Determining the site-specific soil type-based irrigation water requirements requires the development of a soil water characteristics curve ...

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

Ecography, Volume 2026, Issue 8, August 2026.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, Volume 251, Issue 3, Page 1101-1115, August 2026.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.
