Abstract:

The snow condition, the avalanches caused and the dynamic of the avalanches corridors during the winter 2007-2008. Case study, Padinile Frumoase (Piatra Craiului Mountains, Romania). In this paper we aim to present in detail the situations generated by meteorological and morphological parameters, which determined the generation of avalanches of different intensities, on five avalanches corridors in the winter 2007-2008. These are situated in the area named Padinile Frumoase, in the north-eastern part of the Piatra Craiului Mountains, which are situated in the central part of Romania and which belong to the Meridional Carpathians. The relief is represented by a calcareous- conglomeratic ridge, in the high part, the peak reaches over 2000 m altitude. Local conditions determine the forming of avalanches, which are oriented on well defined corridors, along the temporary hydrographic network. By studying the evolution of meteorological parameters and their overlapping with local morphological parameters, the existence of some favourable conditions for the apparition of avalanches were detected. There were noticed both active corridors with traces of avalanches, and inactive corridors on which it was not noticed the manifestation of these phenomena. The material adds up to the data base about the avalanches from this massif, being the second situation of analysed avalanches for this mountainous space totally situated in the National Park Piatra Craiului.
