Relentless 'high water' floods Venice


Venice, November 5 - Venice was once again
underwater Monday in some of the most persistent flooding in
recent memory.
Flood levels reached 110 centimeters before sunrise and
rose again to 105 centimeters in early afternoon local time,
forcing pedestrians to resort to temporary elevated bridges as
water covered St Mark's Square, the Rialto Bridge area and other
crowded walkways.
Venice had recently been subject to one week straight of
unforgiving floods that reached chest-high levels several times,
flooding stores and ground-floor apartments.
Italy has been under a nationwide rainstorm, and autumn
marks the beginning of the 'high water' season, which has been
particularly severe this year.
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.
Weather forecasts predict mild weather until Sunday, when
storms are predicted to pound the country again, and high water
is expected to return to Venice.
