On the response of rockglacier creep to surface temperature increase

A Kääb, R Frauenfelder, I Roer - Global and Planetary Change, 2007 - Elsevier
Besides its thermal characteristics cree** mountain permafrost is substantially defined by
its kinematics. Due to the–in general considerable–ice content of rockglaciers, their …

Mathematical descriptions for the behaviour of ice-rich frozen soils at temperatures close to 0 C

LU Arenson, SM Springman - Canadian Geotechnical Journal, 2005 - cdnsciencepub.com
With the use of creep and constant strain rate (CSR) tests, mathematical formulations were
found that describe the thermomechanical behaviour of ice-rich frozen soils. A Glen-type …

Observations and considerations on destabilizing active rock glaciers in the European Alps

I Roer, W Haeberli, M Avian, V Kaufmann, R Delaloye… - 2008 - zora.uzh.ch
In many high mountain regions, warming of perennially frozen ground in both coarse debris
and rock walls has a major influence on slope stability. In this context, indications of …
