Dr. Sara Savi

I am actually working in the field of applied geomorphology and my main research interests focus on landscape evolution of mountain environments. In particular, my research focuses on the influence of climate and climatic changes on surface processes (sediment supply and sediment transfer) and natural hazards (mainly debris flows and rock falls). I am mainly interested in the understanding of how the modern global warming is affecting sediment dynamics and the evolution of our mountains, for a correct and sustainable management of alpine environments. My research includes morpho-tectonic evolution of mountains and volcanoes, and processes such as landslides and debris-flows. I have experience with field work and data collection, GIS, cosmogenic nuclides, dendrochronology, photogrammetric and remote sensing techniques. I also have experience with physical modeling and the analysis of environmental data.
