Beschreibung

The project is addressed to the analysis of fluvial hazard processes and related flood risk at confluences during hazard events with heavy bedload transport originating from steep tributaries (intense fluvial bedload transport, debris floods / flows), in South-Tyrol and Tyrol. Using data from comprehensive field surveys, geomorphological analyses, and from airborne hydromapping (bathymetry surveys), hydraulic and sediment transport processes at confluences of different types are analysed. Moreover, by means of experimental modelling in the laboratory at the University of Innsbruck (UIBK), different geometrical and process-based boundary conditions will be considered and interpreted in terms of morphologic processes, assessing the effects and influences on hazard potential and flood risk.
