Ten minutes video about the Acqua Alta phenomenon in Venice.
This is an exceptional tide peaks that occur periodically (mainly during autumn) in the Venice Lagoon, partially flooding Venice and Chioggia.
Those events can be categorized as: intense (80 cm – 109 cm); very intense (110 cm – 139 cm) and exceptional high waters (> 140 cm). Venician people are used to these events and the normal life still goes on. Tourist are always amused to see these kind of stuff.
