Snow instability patterns at the scale of a small basin

Snow Cover Patterns and Evolution at Basin Scale: GEOtop Model Simulations and Remote Sensing Observations

Remote sensing data can provide images of snow covered areas and, therefore, it is possible to follow the time evolution of snow melting spatial patterns with increasing spatial and temporal resolution. Snow cover patterns are dominated by the complex interplay of topography, radiation forcings and atmospheric turbulent transfer processes. The snow cover evolution in an alpine basin in Trentino...

Visualizing meltwater flow through snow at the centimetre-to-metre scale using a snow guillotine

Movement of liquid water through snowpacks remains one of the least understood aspects of snow hydrology. Liquid water movement through snowpacks is generally recognized to occur in distinct flow paths rather than as uniform flow through a homogeneous porous medium. Dye tracer experiments have been used in studies of meltwater flow through snow since the 1930s. Although dye tracer experiments h...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

Wet Slab Instability at the Arapahoe Basin Ski Area

Empirical evidence gathered at the onset of ablation on a ski slope where a wet slab avalanche claimed the life of a skier indicates a chance of snowpack fracture. Wetting fronts which fully penetrate the basal layer of depth hoar in response to the first episode of excessive diurnal melt result in a softening of ice-to-ice contact points and a significant change in cup-shaped ice particle geom...
