Avalanche forecasting for transportation corridor and backcountry in Glacier National Park (BC, Canada)
Schweizer, Jürg; Jamieson, J. Bruce (NGI Publication;203, Chapter, 1998)The Avalanche Control Section at Rogers Pass is responsible for avalanche safety on the Trans Canada Highway and Canadian Pacific Railroad within Glacier National Park and for the daily issue of an avalanche warning bulletin ... -
Field measurements of sintering after fracture of snowpack weak layers
Birkeland, Karl W.; Kronholm, Kalle; Logan, Spencer; Schweizer, Jürg (Journal article, 2006)This research documents two cases where field workers unintentionally fractured a snowpack weak layer, but no avalanche released. Measurements from before and after the fractures provide unique data sets on the temporal ... -
Review of spatial variability of snowpack properties and its importance for avalanche formation.
Schweizer, Jürg; Kronholm, Kalle; Jamieson, J.Bruce; Birkeland, Karl W. (Journal article, 2008)The seasonal snow cover is spatially variable. Spatial variability of layer properties is due to various external and internal process drivers interacting with terrain and ground cover during and after the deposition ... -
Snow cover spatial variability at multiple scales: Characteristics of a layer of buried surface hoar
Schweizer, Jürg; Kronholm, Kalle (Journal article, 2007)With the aim of a multi-scale analysis, we simultaneously observed snowpack stratigraphy and stability at three scales: the slope scale, the regional scale and the mountain range scale. The minimum spacing between measurements ... -
Spatial variability of micropenetration resistance in snow layers on a small slope
Kronholm, Kalle; Schneebeli, Martin; Schweizer, Jürg (Journal article, 2004)The mechanisms leading to dry-snow slab release are influenced by the three-dimensional variability of the snow cover. We measured 113 profiles of penetration resistance with a snow micropenetrometer on an alpine snow ...
