Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Uncertainty‐Aware Visual Analysis of Force Networks in 2D Granular Materials

Computer Graphics Forum, EarlyView.
Abstract Uncertainty in experimental measurements makes it challenging to determine which features are intrinsic to the phenomenon and which are most stable and reliable. Granular materials, such as sand, form a complex system in which the forces between individual particles influence the material's macroscopic behavior.

Profiles and Geotechnical Properties for some Basra Soils

Al-Khawarizmi Engineering Journal, 2015
Basra province is known for its logistic location for trading activity and oil industry. By geological point of view, Basra areas are believed to consist mainly of alternation of (clay, silty clay, clayey silt, silt and sand) type of soil.

Comprehensive Analysis for the Evaluation of Torrential Floods and Slope Stability of River Channels: La China River Area (Colombia)

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
Colombia and other tropical regions face a very high threat from torrential floods, which have resulted in over 25,000 deaths in a single event. Unfortunately, there is no comprehensive assessment methodology to zone and determine the magnitude of these disasters; therefore, this research aims to help fill this gap.

Quantifying Multidimensional Effects in Linear Site Response Using 1D and 2D Simulations of Sedimentary Basins in Wellington, New Zealand

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study quantifies the influence of multidimensional effects on site response in the Wellington region of New Zealand by comparing results from different simulation approaches. Response‐spectral amplification functions from 1D and 2D site response analyses are compared to quantify the magnitude and spatial distribution of multidimensional effects ...

Nonstationary Spatial Correlation of Earthquake Ground Motions in California

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Assessing seismic risk to spatially distributed infrastructure systems requires realistic representations of spatially correlated ground motions. Existing models for the spatial correlations of ground motions rely on strong second‐order stationarity assumptions, under which the correlation structure is assumed to be invariant across space, potentially ...

Application of time-lapse ERT to assess heterogeneity in soil moisture dynamics and contaminant plume and associated geotechnical and environmental risks

Discover Geoscience
In modern times, time-lapse electrical resistivity tomography (TL-ERT) has become a powerful investigative tool that can be used in conjunction with regular point-based procedures to track seasonal soil moisture content (SMC) at engineering sites and to ...

Extremecum model for evaluating the thixotropy of structured clays based on the Levenberg–Marquardt algorithm

Ain Shams Engineering Journal
To reveal the correlation mechanism between micro-pore structure evolution and macroscopic mechanical response during the thixotropic process of structured clay, a 150-day thixotropy experiment was conducted on structured clay of the Zhanjiang Formation,

Assessments of Liquefaction Triggering and Manifestation at Three Case History Sites in Napier Based on 1931 Hawke's Bay, New Zealand, Earthquake

Earthquake Spectra, Volume 42, Issue 3, August 2026.
The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.

Development of Liquefaction‐Targeted Design Basis in U.S. Seismic Provisions

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Seismic design criteria for new buildings in the United States have historically focused on life safety performance objectives through minimizing the potential for structural collapse. Development of design criteria to meet this performance objective has evolved over time, leading to the current, risk‐targeted maximum considered earthquake (MCER ...
