Multi-annual and seasonal patterns of Murtèl rock glacier borehole deformation, environmental controls and implications for kinematic monitoring [PDF]

The Cryosphere
Information about rock glacier deformation with depth is crucial for understanding the kinematic processes responsible for variations in rock glacier velocity.

Examining the variability of rock glacier meltwater in space and time in high-elevation environments of Utah, United States

Frontiers in Earth Science, 2023
Rock glaciers are common geomorphic features in alpine landscapes and comprise a potentially significant but poorly quantified water resource. This project focused on three complementary questions germane to rock glacier hydrology: 1) Does the ...

Inventory and changes of rock glacier creep speeds in Ile Alatau and Kungöy Ala-Too, northern Tien Shan, since the 1950s [PDF]

The Cryosphere, 2021
Spatio-temporal patterns related to the viscous creep in perennially frozen sediments of rock glaciers in cold mountains have rarely been studied outside the densely populated European Alps. This study investigates the spatial and temporal variability of

A particle based simulation model for glacier dynamics [PDF]

, 2013
A particle-based computer simulation model was developed for investigating the dynamics of glaciers. In the model, large ice bodies are made of discrete elastic particles which are bound together by massless elastic beams.

A distributed energy-balance melt model of an alpine debris-covered glacier [PDF]

, 2014
Distributed energy-balance melt models have rarely been applied to glaciers with extensive supraglacial debris cover. This paper describes the development of a distributed melt model and its application to the debris-covered Miage glacier, western ...

Projected loss of rock glacier habitat in the contiguous western United States with warming

Journal of Glaciology
Rock glaciers support alpine biodiversity and may respond more slowly to warming than snow or glaciers. While responses of snow and glaciers to climate change are relatively well understood, a robust assessment of rock glacier environmental niche, future

Rapid sequestration of rock avalanche deposits within glaciers

, 2015
Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks.

Characterizing ground ice content and origin to better understand the seasonal surface dynamics of the Gruben rock glacier and the adjacent Gruben debris-covered glacier (southern Swiss Alps) [PDF]

The Cryosphere
Over the recent years, there have been focused international efforts to coordinate the development and compilation of rock glacier inventories. Nevertheless, in some contexts, identifying and characterizing rock glaciers can be challenging as complex ...

Rock Glacier Dynamics by a Thermo-Elastic-Viscoplastic Constitutive Relationship

Geosciences, 2021
As a result of mountain permafrost creep, rock glaciers are common features in high-altitude periglacial areas. From a practical point of view, beyond their localization and inventorying, both the monitoring and prediction of their evolution due to ...
