enice has always been hit by
frequent high tides throughout the
year. Regularly the majority of the
city’s area is flooded and this leads
to Lagoon’s inhabitants discomfort
V and difficulties and to historical and
architectural heritage degrade.
A Consortium was created in order to provide a
definitive solution to protect Venice from flood. The
work is being performed by the Consorzio Venezia
Nuova acting on behalf of the Ministry of Infrastructure
and Transport - Venice Water Authority. This
innovative project is called MOSE, the acronym of
Modulo Sperimentale Elettromeccanico
(Experimental Electromechanical Module).
The scope of this project is to erect and position
artificial dams or barriers which will automatically lift
during high tides or flood risk situation. Four barriers
are placed in front of three harbor entrances (Bocca
di Porto di Chioggia, figure 1, Bocca di Porto di
Malamocco, figure 2, and Bocca di Porto di Lido
Treporti, figure 3 in order to prevent sea streams
from entering the lagoon so that to maintain different
sea levels inside and outside of the lagoon (figure 4).
The integrated defense system is composed of 79 from the sea to the lagoon and effectively reducing Fig. 4 - View of the
