EVOLUTION OF A TIDAL MEANDER DRIVEN BY 120-YEARS OF NATURAL AND
ANTHROPOGENIC MODIFICATIONS OF THE VENICE LAGOON
Leaders: Alvise Finotello (University of Venice, Italy), Marta Cosma (CNR, Italy), Massimiliano Ghinassi (University of Padova, Italy), Andrea D’Alpaos (University of Padova, Italy)
Description: During the last 120 years, feedbacks between rising relative sea levels and anthropogenic interventions have caused severe modifications of the hydrodynamics and morphology of the Venice lagoon (Italy). In particular, the construction of jetties at the lagoon inlets at the beginning of the 20th century, as well as the most recent inlet-modifications related to the installation of mobile gates (Project Mo.S.E.) designed to protect the city of Venice and other lagoon settlements from extensive flooding, caused significant changes in both tidal asymmetries and sediment transport dynamics in tidal channels within the lagoon. In this 1-full-day boat excursion, the evolution of the meandering Gaggian channel will be illustrated directly on the study site, located close to Burano island and the Lido inlet.
Logistics/recommendations: A bus will pick up the participants at the Congress Center in Riva del Garda and drop them near Lio Piccolo, within the Venice Lagoon. Then, a short boat transfer (~30 minutes) will take us to the study site.
During the trip, we will boat from a stop to another, and no cars or buses will be used. Transfers can take up to 1 hour.
During the fieldtrip, short walks are planned in muddy areas, where rubber boots are required. July in Venice is generally very warm and humid, although windy intense rain events cannot be ruled out. Therefore, sunscreen, sunglasses, and a hat are highly recommended, along with a rain jacket.
