A framework for assessing sediment volumes mobilized by debris flows: the case of study of Liera catchments (Dolomites)

Extreme meteorological events cause environmental damages, particularly in mountain areas, which are prone to destructive processes such as landslides and debris flows. An intense storm, named Vaia, occurred from 27th to 30th October 2018 over Northeastern Italy, triggering mass wasting processes, generating new slope instabilities, causing widespread windthrows, and damaging anthropic structures. The objectives of the present study are to create and compare pre- and post-event sediment source inventories and to quantify debris flows mobilized volumes.
