Advances in Climate Change ResearchGlaciers have retreated and shrunk in High Mountain Asia since the mid-20th century because of global warming, leading to glacier instability and hazardous ice–snow avalanches.

Stability of a granular layer on an inclined "fakir plane" [PDF]
, 2012 We present here experimental results on the effect of a forest of cylinder obstacles (nails) on the stability of a granular layer over a rough incline, in a so-called "fakir plane" configuration.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps
Ecography, EarlyView.Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Crack propagation speeds in weak snowpack layers
Journal of Glaciology, 2022 For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred ...

Characteristics of wet-snow avalanche activity: 20years of observations from a high alpine valley (Dischma, Switzerland) [PDF]
, 2018 The occurrence of wet-snow avalanches is, in general, poorly understood. For 20years (winters of 1975-1976 to 1994-1995), the avalanche activity has been observed in the Dischma valley near Davos (Eastern Swiss Alps).

Journal of Quaternary Science, EarlyView.ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

Efficient numerical schemes for viscoplastic avalanches. Part 2: the 2D case [PDF]
, 2018 This paper deals with the numerical resolution of a shallow water viscoplastic flow model. Viscoplastic materials are characterized by the existence of a yield stress: below a certain critical threshold in the imposed stress, there is no deformation and ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Snow avalanche formation [PDF]
Reviews of Geophysics, 2003 Snow avalanches are a major natural hazard, endangering human life and infrastructure in mountainous areas throughout the world. In many countries with seasonally snow‐covered mountains, avalanche‐forecasting services reliably warn the public by issuing occurrence probabilities for a certain region.
