Numerical analysis of desiccation, shrinkage and cracking in low plasticity clayey soils [PDF]

, 2017
This paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking.

Revisiting the thermodynamics of hardening plasticity for unsaturated soils [PDF]

, 2010
A thermodynamically consistent extension of the constitutive equations of saturated soils to unsaturated conditions is often worked out through the use a unique 'effective' interstitial pressure, accounting equivalently for the pressures of the ...

Effects of deficit irrigation and biostimulants on melon productivity and quality in semi‐arid conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Suction cup system‐dependent variable boundary condition: Transient water flow and multicomponent solute transport

Vadose Zone Journal, 2020
Suction cups are widely used in agricultural and environmental research and monitoring under the hypothesis that the sample chemistry represents the soil pore water solute composition around the cup location.

Growing trees on farms: Navigating the goals and values of farmers

People and Nature, EarlyView.
Abstract Agricultural landscapes represent critical contexts for advancing policy objectives related to tree cover expansion. This paper explores how farmers' values influence their willingness or ability to grow trees on farms. Research is based on 49 interviews and two focus groups with farmers in England and draws on two social science research ...

Modelling large deformation problems in unsaturated soils [PDF]

, 2016
Applications of unsaturated soil mechanics often involve large deformations and displacements. This is the case of collapse behaviour of low density soils or the unrestrained swelling of expansive clays.
