In an effort to increase the precision of the density estimates, this study differentiates between snow grain types. 2. METHODS Densities were measured using a 100 cm3 sampling tube and either a portable electronic scale or a Strong Stitch mechanical scale.
WebThe scale was defined by Albert Ferdinand Shore, who developed a suitable device to measure hardness in the 1920s. It was neither the first hardness tester nor the first to be called a durometer ( ISV duro- and -meter ; attested since the 19th century), but today that name usually refers to Shore hardness ; other devices use other measures ...

WebA slab avalanche of relatively dense, compacted snow. These slabs are hard and dense enough (generally greater than 300 kg/m³) that it is difficult to push a single finger into them and are often characterized by hard, blocky debris. Hard slabs can be thin, formed from heavily wind compacted snow, or much thicker, formed as snow hardens under ... WebFor both treatments, we measured with a dedicated snow tribometer the friction coefficient µ on compacted snow at different temperatures (−10 °C; −5 °C; −3 °C) for a gliding speed range between 1 and 6.1 ms −1. We compared the obtained µ values with those of untreated AISI 301H plates and of stone grinded, waxed UHMWPE plates.
WebJan 20, 2024 · Measurements of snow deformation imparted by skis Schweizer and others (1995a, b) show that the most important variable with respect to the penetration of significant deformation is the snow hardness. Harder layers permit less deformation at depth than softer layers, thereby reducing the chance of failure.
