Integrated model for the hydro-mechanical effects of vegetation against shallow landslides [PDF]
Shallow landslides are instability events that lead to dramatic soil mass wasting in sloping areas and are commonly triggered by intense rainfall episodes.

In the UK, there is contradictory evidence as to whether climate warming is worsening groundwater drought through increased evapotranspiration (ET) or whether increased ET is compensated by rising winter rainfall. We integrated a groundwater model into the JULES land surface model.

Sanitary landfill covers are exposed to varying environmental conditions; hence, the state of the clay layer also changes from saturated to unsaturated. The study aimed to predict the unsaturated hydraulic conductivity of the locally available compacted ...

Evaluation Model of Soil Water Characteristic Curve of Red Clay Based on Dielectric Theory [PDF]
[Objective] The soil water characteristic curve (SWCC) can effectively reflect the relationship between soil water suction (matric potential) and water content, yet conventional testing methods pose challenges for the calibration of in situ soil ...

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

The unsaturated permeability curve is governed by the pore-size distribution curve, which can be used to predict the permeability curve. In order to investigate the applicability of this method for compacted loess, three groups of compacted loess samples

Agricultural intensification and the increasing use of fertilizers and irrigation have significantly improved crop productivity but have also led to growing concerns over groundwater contamination and inefficient water usage. When solutes like nitrates and pesticides seep past the root zone, they not only deplete soil fertility but also endanger the ...

Methods of Soil Water Collection at Different Matric Suctions
To investigate the transport mechanism of solutes in soil water in the unsaturated zone, collection of soil water samples having different matric potential is necessary. Three methods originally developed for the purpose of measuring matric suction, i. e., the centrifuging, the pressure membrane, and the vapor pressure depression methods, were used to ...

Determination of the lens water content for several different configurations of elliptical particles in unsaturated soils [PDF]
Until now, all of the calculations about determining of water content around the particles in unsaturated soil have done with supposing the spherical shape of particles and most of quantities such as matric suction and interparticle stress due to water ...
