MARC recordLaboratory experiments on the dynamics of powder-snow avalanches in the run-out zone / Felix Hermann, Kolumban Hutter.
| Title: | Laboratory experiments on the dynamics of powder-snow avalanches in the run-out zone / Felix Hermann, Kolumban Hutter. |
| Author(s): | Hermann, Felix. Hutter, Kolumban. |
| Date: | 1991. |
| In: | Journal of Glaciology. (1991.), Vol. 37(126) (1991) |
| Abstract: | Avalanches simulated as turbulent boundary-layer flows of polystyrene particles in still water along chute with kink and runout zone. Analysis of data shows that concave change in terrain topography acts as efficient mechanism for particle sedimentation, affecting particle concentration and velocity and considerable reduction close to ground, whereas density is reduced throughout depth, leading to reduction of dynamic pressure close to ground and leaving it greater at higher altitudes. Considers implications for field glaciology. |
| Notes: | Journal of Glaciology. Vol. 37(126) :281-295 (1991). |
