Climate Change and Reduction of Soil Organic Layer Thickness Increases Drought Risk in Mountain Forests of the Northern Alps

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Rainfall‐Induced Physical Crusting Is Associated With Near‐Surface Structural Degradation and Strain Localization During Drying in Loess Soil

Land Degradation &Development, EarlyView.
ABSTRACT Rainfall‐induced physical crusting is associated with degradation of near‐surface soil structure, but its pore‐scale structural and mechanical evolution during drying remains poorly resolved. We combined time‐resolved X‐ray computed tomography (XCT), digital volume correlation (DVC), and surface‐aligned stratification to track pore ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Hypoplastic Model for Unsaturated Soils With Degree of Saturation Dependent Stiffness

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents an enhanced hydro‐mechanically coupled hypoplastic constitutive model for unsaturated soils, developed by extending an existing framework, with particular emphasis on improving the stiffness formulation to better capture the influence of the degree of saturation. The existing framework links Bishop's effective stress to the
