Estimation of hydraulic conductivity function in unsaturated pyroclastic soils

E3S Web of Conferences, 2016
A full understanding of slope failure conditions in unsaturated pyroclastic slope needs a fair analysis of groundwater flow and, therefore, a proper hydraulic soil characterization in terms of either soil water retention curves (SWRC) and hydraulic ...

Distinct Proteomic Signatures Driving Progression of Sarcopenia: A Longitudinal Multicohort Study

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Sarcopenia is an age‐related condition characterized by progressive muscle mass, strength and physical performance declines, contributing to frailty and adverse health outcomes. Despite increasing interest in molecular biomarkers, longitudinal data with external validation are limited.

New automatic minidisk infiltrometer: design and testing

Journal of Hydrology and Hydromechanics, 2015
Soil hydraulic conductivity is a key parameter to predict water flow through the soil profile. We have developed an automatic minidisk infiltrometer (AMI) to enable easy measurement of unsaturated hydraulic conductivity using the tension infiltrometer ...

Monitoring of water volume in a porous reservoir using seismic data: Validation of a numerical model with a field experiment

Near Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.
Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

The Role of Internal Sedimentologic and Biotic Structure in Moderating Storm‐Induced Dune Erosion

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Laboratory studies indicate that the magnitude of coastal foredune erosion during high‐energy events is influenced by the belowground biomass and sediment grain size of those dunes. However, the extent to which dune architecture mediates wave‐induced erosion in natural settings is largely unknown.

Comment on “Modified expression for unsaturated hydraulic conductivity according to Mualem–van Genuchten to allow proper computations at low pressure heads” by M. Heinen

Vadose Zone Journal
This comment concerns evaluation of the Mualem–van Genuchten (MvG) unsaturated soil hydraulic functions at very low (negative) pressure heads as described recently in an important study by Heinen.

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

Water Resources Research, Volume 62, Issue 4, April 2026.
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

Estimation of the empirical model parameters of unsaturated soils

E3S Web of Conferences, 2016
For each flow modelling in the unsaturated soils, it is necessary to determine the retention curve and the hydraulic conductivity curve of studied soils. Some empirical models use the same parameters to describe these two hydraulic properties.

Experimental and Numerical Investigation of the Characteristic Length Governing Soil Evaporation in Layered Sands

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract In arid and semi‐arid regions, ecosystems exist with shallow water tables, where evaporation is a key component of the water balance. However, systematically addressing soil evaporation remains challenging due to differing interpretations of the mechanisms that control it.
