Analysis of the snow-atmosphere energy balance during wet-snow instabilities and implications for avalanche prediction
Wet-snow avalanches are notoriously difficult to predict; their formation mechanism is poorly understood since in situ measurements representing the thermal and mechanical evolution are difficult to perform. Instead, air temperature is commonly used as a predictor variable for days with high wet-snow avalanche danger – often with limited success. As melt water is a major driver of wet-snow inst...
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 کاملSlow Drag in 2D Granular Media
We study the drag force experienced by an object slowly moving at constant velocity through a 2D granular material consisting of bidisperse disks. The drag force is dominated by force chain structures in the bulk of the system, thus showing strong fluctuations. We consider the effect of three important control parameters for the system: the packing fraction, the drag velocity and the size of th...
متن کاملSlow Drag in a Granular Medium
We have studied the drag force acting on an object moving with low velocity through a granular medium. Although the drag force is a dynamic quantity, its behavior in this regime is dominated by the inhomogeneous distribution of stress in static granular media. We find experimentally that the drag force on a vertical cylinder is linearly dependent on the cylinder diameter, quadratically dependen...
