SEMINAR TITLE
Future changes in extreme precipitation in the Great Alpine Region

SHORT DESCRIPTION
Understanding how sub-daily precipitation extremes may change is essential for climate change adaptation and flood risk management, particularly in complex terrain prone to natural hazards. This seminar presents a comprehensive study of sub-daily precipitation extremes in the Great Alpine Region, based on observations, a high-resolution ensemble of convection-permitting climate models, and a novel statistical approach for estimating extreme precipitation. Model evaluation against observations reveals dependencies on event duration and elevation, while comparison with radar observations highlights the added value of convection-permitting models over coarser regional climate models, especially at short durations and small spatial scales relevant to mountain catchments. Projections under the RCP8.5 scenario indicate a marked intensification of short-duration extreme precipitation, particularly for higher return periods, with distinct spatial patterns in the Alpine range.

SHORT BIO:
Dr. Eleonora Dallan is an environmental engineer and researcher at the TESAF Department (Land, Environment, Agriculture and Forestry) of the University of Padova, Italy. After professional experience in an engineering consultancy, she earned a Ph.D. in Environmental Engineering and pursued an academic career. Her research focuses on hydrology, particularly rainfall dynamics, extreme precipitation, and their effects on the water cycle, as well as climate-change impacts on rainfall, water resources and rainfall-driven natural hazards. She serves as Vice-President of the International Committee of Statistical Hydrology (ICSH–IAHS) and as Associate Editor of the Journal of Hydrology.
