Venice anti-flood system slammed by Italia Nostra


Venice, December 12 - Italian heritage and
conservation body Italia Nostra on Monday slammed a
controversial flood-prevention system under construction in
Venice for being "incapable" of halting dangerously high water.
"In case of a repeat of the 1966 flood, MOSE would be
incapable of keeping the lagoon waters below 110 centimeters,"
it said in a statement.
The record 'acqua alta' (high water) was in the great flood
of 1966, at 194cm.
Italia Nostra was citing new research from Venetian
engineer Paolo Pizzarolli, a member of France's national
research center.
"MOSE is inadequate to safeguard Venice, and it is not able
to resist flooding," said Italia Nostra. "If it is completed in
2016, according to the most optimistic forecasts, it will have
to be demolished soon thereafter".
When the 5.7-billion-euro project was conceived in 1984,
tide levels were expected to rise by roughly 22cm by the year
According to Italia Nostra, up-to-date projections foresee
an 80cm rise by the end of the century.
Italia Nostra added that even normal flood conditions would
pose a serious threat to the anti-flood system.
"The grandiose MOSE project would be insufficient to
protecting the city from the sea if current climate forecasts
prove accurate," it said.
Floods have reached chest-high levels several times since
this autumn, flooding stores and ground-floor apartments.
The causes are both natural and man-made.
Decades of pumping groundwater caused significant damage to
the delicate foundation before the practice was called off.
Weather experts say the high-water threat has been
increasing in recent years as heavier rains have hit northern
Other possible explanations for the phenomenon include the
sea floor rising as a result of incoming silt and gas extraction
in the sea off Venice undermining the islands.
According to a recent study, plate tectonics are also to
blame as the Adriatic plate is sliding beneath the Apennine
Mountains, causing the area to drop in elevation.
