How does Venice work?

Venice Backstage:

Venice is not just a stage set. It is also a city with a resident population, which has productive activities, transportation and services. But how does the “Venice system” work? How do the tides in the lagoon behave? How are the canals formed? And the embankments? What’s under the buildings?

Venice is a fascinating place. Not only because of its history and culture but its actual physical nature. This is a really well-done video “explaining” the city.
