SPATIAL VARIABILITY OF HYDRO-RELATED PHYSICAL PROPERTIES OF AL-RASHEED LOAM

The Iraqi Journal of Agricultural science, 2022
A field study was conducted on 2 hectare area at Al- Rashid district, south of Baghdad to analyze the spatial variability of saturated hydraulic conductivity (Ks), initial infiltration rate (IR), Porosity (F) and bulk density (BD).

Soil Hydraulic Properties of Europe at 500 m Resolution for Topsoil Using EUPTFv2 and LUCAS Soil Data

Hydrological Processes, Volume 40, Issue 8, August 2026.
ABSTRACT Soil hydraulic properties govern the movement and storage of water in soils and are essential inputs for hydrological and land surface models, influencing water‐holding capacity, matter and energy transport, erosion susceptibility and plant water availability.

A comparative assessment of the estimates of the saturated hydraulic conductivity of two anthropogenic soils and their impact on hydrological model simulations

Soil and Water Research, 2020
In this study, different methods were compared in order to determine the soil hydraulic conductivity at the saturation (Ks) of two heavily anthropized soils in northern Italy: an irrigated field and a landfill cover.

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 ...

Hydro-pedotransfer functions: a roadmap for future development [PDF]

Hydrology and Earth System Sciences
Hydro-pedotransfer functions (PTFs) relate easy-to-measure and readily available soil information to soil hydraulic properties (SHPs) for applications in a wide range of process-based and empirical models, thereby enabling the assessment of soil ...

Climate Change Shows Inverse Effects on Grain Yield and Protein Concentration in West Africa

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Climate change driven shifts in temperature, precipitation patterns, and atmospheric CO2 concentrations threaten both productivity and nutritional quality of maize, a staple crop that underpins daily energy and protein intake for millions of households in Africa and beyond.

TESTING SOME PEDO-TRANSFER FUNCTIONS (PTFS) IN APULIA REGION

Journal of Agricultural Engineering, 2009
The knowledge of soil water retention vs. soil water matric potential is used to study irrigation and drainage schedules, soil water storage capacity (plant available water), solute movement, plant growth and water stress.

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.

Building pedotransfer functions for estimating soil erodibility in southeastern China

Ecological Indicators, 2022
Soil erodibility (K) reflects the sensitivity of soil to detachment and transport and is a key factor for estimating the loss of soil. Most of the models for estimating K are complex and experiential, simple and local estimation model in the hilly and ...

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.
