130 Years of Natural & Anthropogenic Modifications of the Venice Lagoon - Evolution of Tidal Meanders

Explore the morphodynamic evolution of tidal meanders in the Venice Lagoon over the past 130 years in this 53-minute lecture. Examine how natural and anthropogenic modifications have impacted the lagoon's hydrodynamics and morphology, focusing on a meandering tidal channel in the northern region. Analyze extensive datasets including aerial photographs, topographic and bathymetric surveys, geophysical investigations, sedimentary core analysis, and numerical modeling to understand the complex interplay between rising sea levels, human interventions, and channel evolution. Investigate how changes in local hydrodynamics have influenced cross-sectional areas, bed morphologies, and meander planform dynamics. Discuss the effects of altered sediment transport regimes on tidal point-bar sedimentology and explore the potential impact of wave-enhanced suspended sediment concentrations on bedform formation. Gain insights into the unique characteristics of tidal meanders and their differences from fluvial systems through this comprehensive examination of the Venice Lagoon's geomorphological history.
