Geomorphology of the Liera catchment (Dolomites, NE Italy): understanding landscape response to an extreme event

Geomorphological field surveys and mapping have been carried out in a catchment of the Dolomites (eastern Italian Alps) as part research project aiming at assessment sediment availability for mass wasting mountain environments. The study area is Liera which was severely affected by high-intensity, regional-scale storm named ‘Vaia’ (27–30 October 2018), induced relevant morphological changes, caused major flood main stream triggered debris flows many tributaries. This contribution gives snapshot present-day state to improve understanding such landscape characterizing processes that control its geomorphological spatio-temporal dynamics evolution.
