Main publication details
MARC recordExperimental and theoretical study of the dynamics of powder snow avalanches / Pierre Beghin, Xavier Olagne.
| Title: | Experimental and theoretical study of the dynamics of powder snow avalanches / Pierre Beghin, Xavier Olagne. |
| Author(s): | Beghin, Pierre. Olagne, Xavier. |
| Date: | 1991. |
| In: | Cold Regions Science and Technology. (1991.), Vol. 19(3) (1991) |
| Abstract: | Experimental results in water tank show that "thermal theory" is applicable to 3-D flow of buoyant cloud for slope angles between 10 and 90°. Spatial growth rates in height and length are linear functions of shape angle, whereas growth has nearly constant value. Results can be extrapolated to powder snow avalanche to calculate flow variables along track. |
| Notes: | Cold Regions Science and Technology. Vol. 19(3) :317-326 (1991). |
| Keywords: | 551.578.481 -- Avalanches, types. 551.578.482 -- Avalanches. Theory, causes. E10 -- Glaciology: snow and avalanches. |
