Outline of Final Research Achievements |
Soil-snow mixed avalanches are easy to occur in winter on the collapsed slopes induced by the North Nagano prefecture Earthquake on March 2011 and heavy rain fall on 2011 and 2012. We have experimented soil-snow mixed snow avalanche on 5m slope in low -10℃ temperature room and outside, and observed flow length and flow velocity. We founded that dry snow flow longer than wet snow. By changing of mixing ratio of soil and snow, soil-mixed flow change different flow behavior. We simulated soil-snow mixed flow by two phase liquid model. We simulate the snow avalanche flow of avalanche on slopes.
