Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Burgers-type empirical creep model for unsaturated soil considering matric suction

Shenzhen Daxue xuebao. Ligong ban
Reservoir bank slopes are often in an unsaturated state due to water level fluctuations and atmospheric precipitation, which can easily trigger landslides. Therefore, it is necessary to develop a creep model for unsaturated soils that accounts for matric

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Modelling the Thermo-plasticity of Unsaturated Soils

, 2013
This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments.

Common‐Mode Rejection Shifted‐Excitation Raman Difference Spectroscopy (CMR‐SERDS) Preserves Broad Structure Predictive of Soil Organic Carbon

Journal of Raman Spectroscopy, EarlyView.
Common‐mode rejection (CMR) is introduced as a physics‐motivated preprocessing method for shifted excitation Raman difference spectroscopy (SERDS) that removes the shared background of paired measurements while preserving the noncommon excitation‐dependent component. Applied to more than 900 North American soil samples, CMR improves soil organic carbon

Estimation of the shear modulus of unsaturated soils using the capillary model

Scientific Reports
The shear modulus is a fundamental parameter for evaluating soil deformation and stiffness. It is influenced by various factors, including void ratio, confining pressure, soil type, and soil suction (or degree of saturation).

Basal anti-heave stability of foundation pits in unsaturated soils

Yantu gongcheng xuebao
It is known that the soils surrounding a foundation pit are commonly in an unsaturated condition and the displacement of a retaining wall routinely rotates around wall bottom (i.e., RB displacement mode). The bearing capacity of strip foundations at wall
