Acqua alta (“High Water”, Venice), Venezia, Veneto, Italy

Exceptional tide peaks cause partial floods in Venice and other towns and islands in the Venetian lagoon. Most of these phenomena occur in autumn and spring, when the tides are reinforced by seasonal winds, as Sirocco, from South and Bora, from east.

To allow pedestrian circulation, the Majority installs gangways. Besides prior warning alerts to the population with displays and automatic phone calls and messages, intense forecast tidal events has announced by sirens.

The Acqua alta phenomena are ever-growing in the last decades.

A system of mobile darns, to prevent the tidal peaks, is under construction between the lagoon and the Adriatic Sea.
