| Summary: | This PhD thesis has been carried out in the context of a Strategic Project of the University of Padua ("Georisk"), which aim was the study of the geological and hydrological hazards in the north-east of Italy. The project was divided into 5 workpackages (WP) and the PhD study was mainly conducted in the framework of WP1 ("slope processes"). The study focused on the geomorphological evolution of three mountain areas affected by the presence of glaciers at different times. According to the literature, after the glacial mass withdrawal the evolution of these territories is defined "paraglacial evolution". In particular, the study areas are: the Schlinig Valley (Eastern Alps - South Tyrol), the area of Cima Uomo Glacier (Dolomites - Trentino) and the Vauz Basin (Dolomites - Belluno). In the Schlinig Valley the aim was to assess the state of the slopes which are affected by various DSGSDS (Deep Seated Gravitational Slope Deformations). At Cima Uomo the purpose was to understand how the permafrost presence can drive the evolution of the area during and after the deglaciation. Finally, in the Vauz Basin, the aim was to understand the present evolution of this area, which in the past underwent paraglacial modeling processes and modification, as documented by some relict landforms. The detailed study of the three investigated areas allowed to: 1) characterize the current geomorphological processes, 2) understand the past morphological evolution and 3) better understand the developmental status achieved in each area with respect to the paraglacial period. The three study areas highlight the importance of the local topo-climatic factors on the characteristics of paraglacial evolution processes, deposits and landforms respect to the wider scale climatic factors. La presente tesi di Dottorato è stata realizzata nell’ambito di un Progetto Strategico dell’Università degli Studi di Padova (“Georisk”), il quale aveva come obiettivo lo studio dei rischi geologici e idrologici nell’Italia nord orientale. Il Progetto strategico ...
