Acqua Alta in Venice
Venice is a city of intricate architecture, historic canals and romantic gondola rides. Unfortunately is facing a recurring environmental phenomenon known as" acqua alta " or "high water". Actually this term refers to the exceptionally high tides that cause flooding in the streets and squares of Venice. So, it's a great challenge for its residents and the preservation of historic environment.
What is The Phenomenon of Acqua Alta?
Acqua alta is a natural phenomenon. It occurs when different factors by combining together such as lunar tides, wind and atmospheric pressure cause the water of Adriatic Sea to rise. In this way there is flood in the Venetian lagoon. Mostly these conditions are prevalent between autumn and early spring, particularly during the months of November and December.
When there is acqua alta, water levels rise quickly and it causes flooding in public areas. Businesses and the ground floor of buildings face the worst. The severity of the flooding depends on the volume of water and the prevailing meteorological conditions.
Why the term of "The Sinking City" is used for Venice?
Since the existence Venice has a delicate union with the sea. Venice is built across 118 small islands and these are connected by a network of canals. The first reported flood dates back to 782AD and in 1110 AD. Palaces and churches of Venice are raised upon thousands of wooden piles driven deep into the earth which is causing the city to subside . Therefore, it wouldn't be wrong to say that Venice is gradually sinking into the soft ground on which it is built. Studies describe that the city has sunk by about 23 centimeters over the last century due to both natural and human -induced factors.
What is the impact of Climate Change?
Climate change plays a significant role in the increasing frequency and severity of acqua alta events. Sea levels are rising because of melting ice caps and glaciers. The increased frequency of extreme weather events can intensify sirocco winds which pushes even more sea water in the Venetian Lagoon.
Coping Strategies
Elevated wooden walkways called"passerelle" are set up across the city to facilitate pedestrian movement during the acqua alta. Businesses and residents of the city may use temporary barriers and flood-proof doors to protect their properties.
In order to prevent flooding the Italian government has embarked a project known as Mose .In this project there is series of mobile gates to isolate the Venetian lagoon from the Adriatic Sea during high tides.
