Title: Wet Snow Diurnal Evolution and Stability Assessment: Date: 2009; Authors: Frank Techel, Christine Pielmeier; Description: Wet snow avalanches pose a threat to snow recreationists and to infrastructure such as mountain roads. The timing of wet snow avalanche formation is d...; Object ID: issw-2009-0256-0261.pdf; Keywords: wet snow, snow stability, water content, rutschblock test, extended column test, shovel shear test, persistent weak layer; View additional details about Wet Snow Diurnal Evolution and Stability Assessment

Title: Extended Column Test Results During Surface Warming: Does Surface Warming Affect Fracture Propagation Potential?: Date: 2008-09-22; Authors: Ron Simenhois, Karl Birkeland; Description: Dry slab avalanche stability typically increases over time in the absence of active loading from new snow or wind. However, field observations suggest...; Object ID: P__8037.pdf; Keywords: extended column test, pst, propagation saw test, fracture propagation; View additional details about Extended Column Test Results During Surface Warming: Does Surface Warming Affect Fracture Propagation Potential?

Title: Comparing Fracture Propagation Tests and Relating Test Results to Snowpack Characteristics: Date: 2008-09-26; Authors: Cameron Ross, Bruce Jamieson; Description: The Propagation Saw Test (PST) and the Extended Column Test (ECT) are two recently and independently developed field tests that indicate the propensit...; Object ID: P__8177.pdf; Keywords: fracture propagation, snowpack stability test, extended column test, propagation saw test, avalanche forecasting, snowpack properties; View additional details about Comparing Fracture Propagation Tests and Relating Test Results to Snowpack Characteristics

Title: The Extended Column Test: Test Effectiveness, Spatial Variability, and Comparison with the Propagation Saw Test: Date: 2008-09-26; Authors: Karl W. Birkeland, Ron Simenhois; Description: The Extended Column Test (ECT) is a new stability test that aims to assess the fracture propagation potential across a 90 cm wide isolated column. Ini...; Object ID: P__8190.pdf; Keywords: ect, extended column test, fracture propagation, stability evaluation, avalanches; View additional details about The Extended Column Test: Test Effectiveness, Spatial Variability, and Comparison with the Propagation Saw Test

Title: The Effect of Changing Slab Thickness on Fracture Propagation: Date: 2008-09-22; Authors: Ron Simenhois, Karl Birkeland; Description: Many avalanches are triggered from shallower parts of a slope. Past research demonstrates that initiating fractures in such areas is easier than in de...; Object ID: P__8045.pdf; Keywords: ect, extended column test, pst, propagation saw test, fracture propagation; View additional details about The Effect of Changing Slab Thickness on Fracture Propagation

Title: Evaluating a Prototype Field Test for Weak Layer Fracture and Failure Propagation: Date: 2006; Authors: Dave Gauthier, Bruce Jamieson; Description: Researchers and practitioners currently lack a quantitative field test that indicates the propensity of a given slab and weak layer combination to pro...; Object ID: issw-2006-107-116.pdf; Keywords: fracture propagation, field test, extended column, snowpack stability, avalanche forecasting; View additional details about Evaluating a Prototype Field Test for Weak Layer Fracture and Failure Propagation
