LandRockfalls can cause loss of life and material damage. In Northern Morocco, rockfalls and rock avalanche-deposits are frequent, especially in the Dorsale Calcaire morpho-structural unit, which is mostly formed by Jurassic limestone and dolostone ...

Boreas, EarlyView.Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Investigating submerged morphologies by means of the low-budget “GeoDive” method (high resolution for detailed 3D reconstruction and related measurements) [PDF]
, 2018 Geophysical methods allow to collect geological data on lake and sea bottoms and characterize large areas, even at high depths, but with high costs.

A nonlinear model coupling rockfall and rainfall intensity based ewline on a four year measurement in a high Alpine rock wall (Reintal, German Alps) [PDF]
Natural Hazards and Earth System Sciences, 2009 A total of more than 140 000 kg of small-magnitude rockfall deposits was measured in eight rockfall collectors of altogether 940 m<sup>2</sup> in size between 1999–2003 below a 400–600 m high rock face in the Reintal, German Alps ...

Semi-Automatic Determination of Rockfall Trajectories
Sensors, 2014 In determining rockfall trajectories in the field, it is essential to calibrate and validate rockfall simulation software. This contribution presents an in situ device and a complementary Local Positioning System (LPS) that allow the determination of ...

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)
Boreas, EarlyView.Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Applied Sciences, 2022 The rockfall process is characterized by bounces of a block on the ground. The coefficient of restitution (COR), which indicates the degree of rockfall energy dissipation, has a significant effect on the rockfall trajectory.

Boreas, EarlyView.The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

QuaRRi: a new methodology for rock-fall risk analysis and management in quarry exploitation [PDF]
, 2010 Rockfall is one of the most critical geological events that can affect quarrying activities. Nevertheless, few tools are currently available to help designers and managers correctly define the risk conditions and quantify the advantages, in terms of ...
