The 2022 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Davide Tognin for the poster/PICO entitled:

Salt-marsh sedimentation affected by storm surges and anthropogenic impacts (Tognin, D.; D'Alpaos, A.; Ghinassi, M.; Marani, M.; Carniello, L.)

Davide Tognin recently completed his PhD under the supervision of prof. Luca Carniello and prof. Andrea D’Alpaos at the University of Padova (Italy), where he is currently a postdoctoral researcher. His research focuses on spatial and temporal sediment transport dynamics in shallow tidal environments and how they are affected by climate change and human interventions.

The awarded presentation at EGU 2022 analyzed the temporal variability of sedimentation on the salt marshes in the Venice Lagoon (Italy), which recently became regulated by a storm-surge barrier, known as the Mo.S.E. system. Salt-marsh sedimentation was measured with monthly frequency or immediately after each storm-surge event from October 2018 to October 2021. The results show that most of the salt-marsh sedimentation (more than 70%) occurs due to sediment reworking during storm surges and that the large, yet episodic storm-driven sediment supply is seriously reduced by operations of storm-surge barriers, revealing a critical competition between the objectives of coastal flooding protection and preservation of salt marshes.
