A Depth-Averaged Material Point Method for Shallow Landslides: Applications to Snow Slab Avalanche Release
Johan Alexandre Philippe Gaume, Lars Kristoffer Uhlen Blatny, Bertil Trottet, Denis Aloyse Joseph Steffen, Louis Marie Cédric Guillet
Shallow landslides pose a significant threat to people and infrastructure. Despite significant progress in the understanding of such phenomena, the evaluation of the size of the landslide release zone, a crucial input for risk assessment, still remains a c ...
AMER GEOPHYSICAL UNION2023Global spatial analysis of toxic emissions to freshwater: operationalization for LCA
PurposeThere is increasing interest in using fate and exposure models to spatially differentiate the impacts of chemical emissions. This work aims at exploring the operationalization in life cycle assessment (LCA) of spatially differentiated models for tox ...
SPRINGER HEIDELBERG2019Initiation of secondary ice production in clouds
Disparities between the measured concentrations of ice-nucleating particles (INPs) and in-cloud ice crystal number concentrations (ICNCs) have led to the hypothesis that mechanisms other than primary nucleation form ice in the atmosphere. Here, we model th ...
Copernicus GmbH2018Influence of weak-layer heterogeneity on snow slab avalanche release: application to the evaluation of avalanche release depths
Johan Alexandre Philippe Gaume
The evaluation of avalanche release depths constitutes a great challenge for risk assessment in mountainous areas. This study focuses on slab avalanches, which generally result from the rupture of a weak layer underlying a cohesive slab. We use the finite- ...
2013South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy
Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai
The IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore >100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity ...
Int Glaciol Soc2013A natural shock-induced dense polymorph of rutile with alpha-PbO2 structure in the suevite from the Ries crater in Germany
A dense post-rutile titanium dioxide (TiO2) phase was discovered in shocked garnet gneisses from the Ries crater by reflected-light microscopy, laser rnicroRaman spectroscopy and micro-beam X-ray diffraction. The Raman spectrum consists of nine bands at wa ...
