High Tide is the mean to indicate the phenomenon of peak tidal.
This appens with frequency in the Venetian Lagoon during spring and autmn.
On High Tide period a system of wooden palnks will be arranged to guarante a dry passage through the main street up to a tide level of 120 cm.
The city remembers particularly the high tide on 4th November 1966 that stayed over 110 cm for nearly 24H.
Few years ago a new project called MOSE, would allow the elimination of exceptional high waters through mobile barriers at the Port entrance.
