Dense Avalanche Friction Coefficients Influence of Nivological Parameters
High altitudes, heavy snow, and sharp mountainous relief of Mont Blanc massif make the upper part of the Arve valley (Chamonix, France) one of the most threatened areas by snow avalanches. 115 paths from this area were included in the avalanches national observatory, 26 of them have experienced between 20 and 100 events over a period of almost 100 years, among these avalanches 729 are posterior...
متن کاملMars: Wind Friction Speeds for Particle Movement
Wind friction threshold speeds (V,t) for particle movement were determined in a low pressure boundary layer wind tunnel at an atmospheric pressure of 5.3 mb. The results imply that for comparable pressures on Mars, the minimum V,t is about 2.5 m/sec, which would require free-stream winds of 50 to 135 m/sec, depending on the character of the surface and the atmospheric conditions. The correspond...
متن کاملAvalanche Dynamics and Trading Friction E ects on Stock Market Returns
We propose a model with heterogeneous interacting traders which can explain some of the stylized facts of stock market returns A generalized version of the Random Field Ising Model RFIM is introduced to describe trading behavior Imitation e ects which induce agents to trade can generate avalanches in trading volume and large gaps in demand and supply A trade friction is introduced which by resp...
متن کاملAvalanche dynamics of elastic interfaces.
Slowly driven elastic interfaces, such as domain walls in dirty magnets, contact lines wetting a nonhomogeneous substrate, or cracks in brittle disordered material proceed via intermittent motion, called avalanches. Here we develop a field-theoretic treatment to calculate, from first principles, the space-time statistics of instantaneous velocities within an avalanche. For elastic interfaces at...
متن کاملFriction versus texture at the approach of a granular avalanche.
We perform an analysis of the granular texture of a granular bed close to stability limit. Our analysis is based on a unique criterion of friction mobilization in a simulated two-dimensional packing. In this way, we recover the bimodal character of granular texture and the coexistence of weak and strong phases in the sense of distinct contacts populations. Moreover, we show the existence of a w...
