Walls of Venice: The Complex Engineering of the Mobile Walls

The video discusses the MOSE project, a complex civil engineering endeavor aimed at protecting Venice from flooding. It highlights the environmental and governmental prerequisites, such as maintaining the lagoon's visual and hydrodynamic characteristics. The project involves constructing floating barriers that rise to block water during adverse conditions. The barriers are filled with air to float, utilizing the Archimedes effect. The video also covers the construction process, including the use of prefabricated caissons and precise installation techniques.

What is the primary purpose of the Venice flood prevention project?

• To enhance tourism in Venice
