From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone
Journal of Quaternary Science, EarlyView.ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Assessment of seismic performance of adobe structures in Pakistan and Portugal
, 2012 Adobe buildings exist in different parts of the world. The construction of these buildings can be carried out economically, using locally available materials and skills that do not require use of modern machinery.

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds
The Journal of Wildlife Management, EarlyView.Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

SEISMIC HAZARD ANALYSIS OF SONDUR DAM SITE OF CHHATTISGARH STATE
, 2015 Seismic vulnerability analysis, an approach to get an estimate of the strong ground-motions at any particular site, is mainly intended for earthquake resistant designs or for seismic safety assessments. The hazard analysis usually attempts to analyze two

A novel approach for in situ benthic habitat characterization
Limnology and Oceanography: Methods, EarlyView.Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.
