Evolution of rock glaciers and alpine glaciers: A model–model approach
The effects of horizontal stress transmission on the transient evolution of non-linear viscous bodies having aspects ratios similar to active alpine rock glaciers is investigated. This is done through a comparison between a shallow-ice model, which predicts material flux to be a local function of thickness and slope, and a finite-element model, which solves the full Stokes problem. For length-t...
متن کاملRock glaciers on Mars viewed with Google Earth
Several glacier-like landforms have been identified on Mars. We can view some of them with Google Earth and its virtual Mars planet. In the images of Ismeniae Fossae glaciers, the flow lines of these landforms are clearly visible too.
متن کاملThe evolution of a submarine landform record following recent and multiple surges of Tunabreen glacier, Svalbard
This study focuses on the glacial landform record associated with recent surge events of Tunabreen a calving tidewater glacier in Tempelfjorden, Spitsbergen. Submarine geomorphology and recent terminal fluctuations of Tunabreen’s glacier front were studied using high-resolution multibeambathymetric data and a range of published and remotesensing sources, including topographic maps, satellite im...
متن کاملImage 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 ...
متن کامل13: Scattering from Rock and Rock Outcrops
In terms of target detection and classification, scattering from exposed rock on the seafloor, (i.e., individual rocks and rock outcrops) presents some of the most difficult challenges for modern MCM and ASW sonar systems in shallow water. Work on characterizing, modeling and simulating mean levels and other statistical measures of acoustic scattering from rocks and rock outcrops is therefore c...
