one of the natural hazards in mountainous areas, which always cause great losses of life and financial damages, is the avalanche fall. since, survey the avalanche-prone areas for prevention the probable damages is considerably important, especially when the avalanche paths affect the residential areas or roads. in this research, based on local information, one of the avalanche paths in the chah...

Natural disturbances have been among the most important driving factors in many ecosystems. Anthropogenic suppression of various disturbances has led to documented changes in ecosystem structure and function. Avalanche disturbances are one of the most important processes in many subalpine ecosystems world-wide and avalanche tracks provide unique habitat for various animal and plant species. Ove...

Snow avalanches pose a threat to settlements and infrastructure in alpine environments. Due to the catastrophic events in recent years, the public is more aware of this phenomenon. Alpine settlements have always been confronted with natural hazards, but changes in land use and in dealing with avalanche hazards lead to an altering perception of this threat. In this study, a multi-temporal risk a...

With the principle of the time expansion chamber and the additional measurement of the position of the avalanche along the circumference of the anode wire it is possible to reconstruct the spatial distribution of the primary ionization in space. A position resolution for minimum ionizing tracks of a 5 30 urn is expected. First tests and concepts for vertex detectors are presented.

The Madagascar seasat dataset presents a problem where data are collected along crossing tracks. These tracks are not straight, and appear to be irregular in the model space. Previous methods assumed that the data were regularly sampled in the model space coordinate system. I warp the model space to look more like the data space, so that prediction-error filters can be estimated in the more reg...
