Snow 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 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 کاملRemote Sensing Tools for Snow and Avalanche Research
Since the first images acquired from airplanes (1915) and satellites (1960), remote sensing has had a great impact in diverse number of fields such as meteorology, military, topographic mapping, archaeology and forestry. Today remote sensing has even become a common tool for the general public, with location searches using high spatial resolution (< 1m) imagery on GoogleEarth or Bing Maps. The ...
متن کاملAnalysis 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 کاملAn Information States Blackboard as an Intelligent Querying Interface for Snow and Avalanche Data
We present the graph-based querying paradigm used in the Regional Avalanche Information and Forecasting System (RAIFoS) for the collection and analysis of snow and weather related physical parameters in the Swiss Alps. The querying paradigm relies upon the issue of interactively constructing a semantically valid query graph on an Information States Blackboard as guided by meta-data elements sta...
