Venice braces for waist-deep flooding


Rome, October 29 - Venice waded through its third
straight day of 'high water' flooding on Monday as it braced for
record tides later in the week.
Water levels were 103 centimeters above normal early
Monday, and meter-high flooding was also likely Tuesday.
Worse still, Venice's tide-warning system predicted flood
levels at 140 centimeters on Wednesday.
On Saturday runners and spectators at the Venice Marathon
had to resort to portable elevated bridges in order to escape
rising water amid heavy rain.
Italy is currently under a nationwide rainstorm, and autumn
marks the beginning of the high-tide season, when water
routinely spills over the city's banks, flooding its streets and
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.
Scientists have conceived various ways of warding off the
waters since a catastrophic flood in 1966 and a system of
moveable flood barriers called MOSE is near completion after
years of controversy.
