Avalanche winter 1999. The importance of the snow entrainment in catastrophic avalanches / B. Sovilla, U. Gruber.

Title: Avalanche winter 1999. The importance of the snow entrainment in catastrophic avalanches / B. Sovilla, U. Gruber.
Author(s): Sovilla, B.
Gruber, U.
Date: 2002.
Language: Russian transliteration entered into original records using BGN/PCGN 1947 romanisation of Russian; Cyrillic text in MARC 880 field(s) reverse transliterated from this by automated process; BGN/PCGN 1947 text then upgraded to Library of Congress romanisation.
In: Materialy Gli︠a︡t︠s︡iologicheskikh Issledovaniĭ. (2002.), Vol. 93 (2002)
Abstract: Examines deficiencies in avalanche hazard maps of Obergoms valley in central Swiss Alps revealed during extraordinary avalanche season. About 1200 avalanches led to damage to buildings, transportation infrastructure and power lines, and 17 deaths. Considers neglect of entrainment along avalanche path as partial cause of deficiencies including underestimation of runout distances and undersizing of dams. Describes avalanche data, entrainment theory, numerical model and simulations. Concludes entrainment increased avalanche volumes by factor 1.9 - 3.4, and that simulations performed using observed release and Swiss guideline calibration parameters generally strongly underestimate runout distances and deposition volumes. Presented at International Symposium on Avalanches, September 2001, Kirovsk, Russia.
