Mountain glacier-to-rock glacier transition

Glacier shrinkage across High Mountain Asia

An assessment of glacier shrinkage (reduction of area) for all of HighMountain Asia requires a complete compilation of measured rates of change and also a methodology for objective comparison of rates. I present a compilation from 155 publications reporting glacier area changes, and also a methodology that overcomes the main obstacles hindering comparison. Glacier areas are not always assigned ...

Image Measurement Techniques in Rock Glacier Modelling

Rock glacier is a rare case of study for 3D modelling. We use a stereo feature-based method and multi-view stereo reconstruction algorithms to get different types of cartography. The proposed method has been tested in a real rock glacier example (Veleta in Sierra Nevada, Spain) for producing maps with good results. This rock glacier is of high scientific interest because it is the southernmost ...

Measuring rock glacier surface deformation using SAR interferometry

The detection and quantification of surface deformation of an active rock glacier using the differential SAR interferometry technique is presented. An average deformation rate of 6 mm/35 days in the radar line-of-sight in the summer of 1992 was estimated. The maximum deformation rate was located at the upper part of the rock glacier and amounts to 18 mm/35 days. In contrast, at the snout of the...
