Acqua Alta

Acqua Alta is a natural tidal phenomenon in Venice, Italy, where very high tides cause the seawater level to rise significantly, flooding parts of the city. These floods occur when strong winds and specific astronomical conditions push water into the Venetian Lagoon, raising water levels beyond normal. Acqua Alta often happens in autumn and winter and can flood streets, squares, and buildings, impacting residents and tourists. The city has implemented measures like raised walkways and barriers to manage these high tides, but the phenomenon remains a noteworthy aspect of Venice's relationship with its unique geographic setting.
