No full textINTRODUCTION
The exceptional flood of 4 November 1966, marked
a milestone in the international concern for Venice,
and this is also true for the efforts for the quantitative
forecasting of the water level in the lagoon.
Around 1970 the interest in this challenge involved
many scientific centres all around the world, so that
in 1972 the oceanographer W. Munk reported thirteen
research institutes developing prediction techniques
for Venice (Munk and Munk, 1972). The results
were significant, even though the complexity of the
problem does not allow, even today, the claim that a
definitive solution has been found.
Over the years, these research interests have been
paralleled by the development of questions from an
operational point of view. The historical Hydrographic
Office of the Magistrato alle Acque is complemented
by a service of the city of Venice, the Centre for Tides,
committed to alerting the city, initially by using sirens,
and, step by step, by the various modern tools of high
technology, like the internet and the Short Message
System (SMS). Moreover, a deeper interest has grown
from the perspective of the mobile barriers, for which
a long-term forecast becomes important. It is not correct
to say that the need for prediction is limited to
flood events. For a town like Venice, for example, the
very low tides are also dangerous; one thinks of their
effect in each ‘rio’ (small, internal canal), on commercial
traffic and much more on the rescue boats. Many
considerations force a general request for the forecasting
of all water levels, including the intermediate ones
(Boarto et al., 2001)
