The high tide in Venice

The tide in Venice is measured and predicted on the historic zero of the city. The illustrations indicate a tide level that can affect the walkable ground of three reference areas.

For example: because the Piazza San Marco, one of the lowest points in the city, begins to flood, it takes a tide of over 80cm. At Rialto, in front of the public transport wharves, is needed a tide of over 105cm while in front of the railway station, a very high area in the city, 135cm are needed.
