Effects of ground freezing and snow avalanche deposits on debris flows in alpine environments
Debris flows consist of a mixture of water and sediments of various sizes. Apart from few exceptions, the water is usually contributed directly from precipitation. In a high mountain environment like the Alps, it appears necessary to consider infiltration of water into the ground during rainfall events, the runoff characteristics and the potential supply of sediment as a function of a multitude...
متن کاملComputational snow avalanche simulation in forested terrain
Two-dimensional avalanche simulation software operating in three-dimensional terrain is widely used for hazard zoning and engineering to predict runout distances and impact pressures of snow avalanche events. Mountain forests are an effective biological protection measure against avalanches; however, the protective capacity of forests to decelerate or even to stop avalanches that start within f...
متن کاملSnow Avalanche Admonisher through Wireless Sensor Network
The temperature reaches around -40C to -60C in hilly and mountainous areas during winters which may lead to many probable natural hazards. Defence personnel as well as civilians are unaware of these hazards. Amongst all the natural hazards, Snow Avalanche is one of the major hazards which has the probability of occurrence in the above listed temperature range. The aim of this paper is to bring ...
متن کاملSnow metamorphism: A fractal approach.
Snow is a porous disordered medium consisting of air and three water phases: ice, vapor, and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton. The quantitative relationship between density and morphological characteristics of different snow microstructures is still an open issue. In this work, a three-dimensional fract...
متن کاملMagnitude-Frequency Distribution of Hummocks on Rockslide-Debris Avalanche Deposits and Its Geomorphological Significance
A magnitude-frequency analysis of rockslide-debris avalanche deposits was performed. Hummocks are conical mounds formed in debris avalanche deposits from the catastrophic sector collapse of a mountain (often volcanic) that represent relatively cohesive fragments of the mountain edifice. Examination of 17 debris avalanche deposits in Japan and the Philippines showed that, in general, the larger ...
