Dynamic characteristics and fragmentation evolution of columnar rockfall: A case study of the Zengziyan rockfall in Chongqing, China

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2022
Columnar rockfall occur widely in China and cause extreme damage to man-made structures and facilities. On 12 August 2004, Zengziyan W12 perilous rock collapsed and ran out a horizontal distance of 600 m. The rockfall caused airblast with a height of 150

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Comparing Flow-R, Rockyfor3D and RAMMS to Rockfalls from the Mel de la Niva Mountain: A Benchmarking Exercise

open access: yesGeosciences, 2023
Rockfall simulations are often performed at various levels of detail depending on the required safety margins of rockfall-hazard-related assessments. As a pseudo benchmark, the simulation results from different models can be put side-by-side and compared

A talus rock glacier in Nantlle Valley, North Wales

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Rockfall Mitigation Measures [PDF]

open access: yes, 1996
Highways in Kentucky contain numerous rock slopes and rockfall from these slopes represent potential dangers to motorists. As these highway rock cut slopes age and deteriorate because of weathering, the potential for rockfall and rock slides increases ...

Numerical Simulation of a Shed-Tunnel Structure’s Dynamic Response to Repeated Rockfall Impacts Using the Finite Element–Smoothed Particle Hydrodynamics Method

open access: yesBuildings
In practical engineering, a shed-tunnel structure often encounters repeated impacts from rockfall during its whole service life; therefore, this research focuses on exploring the dynamic response characteristics of shed-tunnel structures under repeated ...

Disposition Model for Permafrost Degradation in Mountainous Regions

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...
