Is climate change causing increased rockfall frequency in Austria? [PDF]
Natural Hazards and Earth System Sciences, 2012 Potentially, increasing rockfall hazards triggered by climate change are a major concern expressed both in scientific and non-scientific media. An existing rockfall inventory for Austria including 252 events from ca.

Experimental testing of low energy rockfall catch fence meshes [PDF]
, 2018 Flexible catch fences are widely used to protect infrastructure like railways, roads and buildings from rockfall damage. The wire meshes are the most critical components for catch fences as they dissipate most of the impact energy.

Forensic analysis of rockfall scars [PDF]
Geomorphology, 2017 Abstract We characterise and analyse the detachment (scar) surfaces of rockfalls to understand the mechanisms that underpin their failure. Rockfall scars are variously weathered and comprised of both discontinuity release surfaces and surfaces indicative of fracturing through zones of previously intact rock, known as rock bridges.

Three-dimensional rockfall shape back analysis: methods and implications [PDF]
Natural Hazards and Earth System Sciences, 2019 Rockfall is a complex natural process that can present risks to the effective operation of infrastructure in mountainous terrain. Remote sensing tools and techniques are rapidly becoming the state of the practice in the characterization, monitoring and ...

Slope-Scale Rockfall Susceptibility Modeling as a 3D Computer Vision Problem
Remote Sensing, 2023 Rockfall constitutes a major threat to the safety and sustainability of transport corridors bordered by rocky cliffs. This research introduces a new approach to rockfall susceptibility modeling for the identification of potential rockfall source zones ...

Repetitive Rockfall Trajectory Testing [PDF]
Geosciences, 2018 Numerical simulations of rockfall trajectories are a standard procedure for evaluating rockfall hazards. For these simulations, corresponding software codes must be calibrated and evaluated based on field data. This study addresses methods of repeatable rockfall tests, and investigates whether it is possible to produce traceable and statistically ...

Characterizing geologic and climatic controls on rockfall hazards using an inventory and integrated kinematic and runout model: Skagway, Alaska, USA [PDF]
Natural Hazards and Earth System SciencesRockfall is common in steep terrain and poses a hazard to nearby communities. While rockfall triggering mechanisms are highly variable and difficult to quantify, the susceptibility of rock slopes to planar, wedge, or toppling failure can be readily ...

ISPRS International Journal of Geo-Information, 2020 Rockfalls are one of the most common natural hazards in mountainous areas that pose high risk to people and their activities. Rockfall risk assessment is commonly performed with the use of models that can simulate the potential rockfall source ...

Thermal structure of a gas-permeable lava dome and timescale separation in its response to perturbation [PDF]
, 2009 The thermal boundary layer at the surface of a volcanic lava dome is investigated through a continuum model of the thermodynamic advection diffusion processes resulting from magmatic gas flow through the dome matrix.
