Is Venice Sinking?

world

Venice, Italy is one of the world's most beautiful cities. It is a city that should be seen with a loved one, and if reports are true, it should be seen before it disappears completely into the surrounding waters. Is Venice really sinking into its waters, never to be seen again? Venice is sinking slowly, but as with most coastal towns and cities, the sea level is also rising.

Venice was built on marshlands, a sedimentary island within a lagoon off the coast of Italy. Attila the Hun invaded Italy in 452, forcing many inhabitants to flee to the coast. A small group of islands in the center of a lagoon were collectively called Rivo Alto, or "high bank." The area soon expanded, and Ri'Alto became the center of Venice.

Venice is a warren of canals. Where most cities have roads, Venice has canals. Gondolas and water taxis transport people to and from destinations. With water levels rising, flooding has become a serious problem and is contributing to Venice sinking. During the high tides in autumn and winter, the Piazza San Marco, the lowest area of the island, becomes totally flooded with water.

When the high tide season arrives, the streets of Venice become blocked with water. Wooden walkways must be erected in order for pedestrians to walk safely. The high water level is causing damage to Venice and disruption to its inhabitants. It has now reached the point at which city governors see the problem as critical.

Venice has always been slowly sinking. Over the last 1,000 years, it has sunk by around seven centimeters for every century, but recent reports have stated that in the last century alone, the city of Venice has lowered by around 24 centimeters. This may have more to do with global warming and the melting polar ice caps than with Venice sinking into its own foundations.

Global warming is an issue that is taken very seriously and is a major environmental concern for towns and cities that are coastal or built on islands. Reports have shown that the ice caps are melting at their fastest rate ever, and it is becoming a critical issue. Experts are seriously addressing the issue in order to find a solution to the problem.

The level to which Venice is sinking is now seen as critical. Many theories and concepts are being developed to stop Venice sinking. City leaders are now considering investing in huge steel gates to block the floods in order to stop Venice sinking. The cost of this project is estimated at around two or three billion euros, but will this enormous price tag be enough to stop Venice sinking?

Many experts say that this solution to stop Venice sinking can only be short term and will only help stem the floods for the next 20 or 30 years. A long-term solution must be found to stop Venice sinking that includes dealing with the causes of global warming. If not, Venice sinking into its own waters may be another chapter in world history.

Venice has been slowly sinking for centuries, but like the article states it *appears* to be sinking faster in the past century because the oceans are rising vs. Venice compacting it's foundations.

There are numerous articles, reports, papers that can show the amount the world's oceans have risen in the past 50 years. Global climate change is the direct cause of rising oceans due to melting glaciers man-made or not. This is compounding the problems in Venice, but is not the sole cause.

"Reports have shown that the ice caps are melting at their fastest rate ever". What "reports"? That's pretty vague misinformation you're posting there. There are *no* conclusive reports to suggest that global warming is having any effect on the ice caps melting any faster than they would naturally during this climate cycle, and *no* evidence to suggest the waters are rising on account of this. If all the polar ice caps suddenly melted the waters of the whole planet would only rise a few feet anyway, so stop blaming everything on global warming!

Venice is sinking because A. It's centuries old and built on wooden pilings; B. Extraction of the aquifer in the 20th century (which was later banned in the 1960's because it was found that this was a major contributing cause to the sinking of Venice). Don't pollute the internet with your global warming conspiracy theories and claim them as 'fact'. The Earth knows more about our climate than 'man' could ever fathom to destroy. We are not that significant, hate to break it to you.

Can someone explain to me simply why venice is sinking and what people are doing to stop it because i have to do a research report on it?

no. if the world worked like that America would have capsized years ago!

its sinking because the city is built on an alluvial base which is consolidating at a slow pace.

basically the ground under Venice is squashing because it's rubbish soil.

Well, Anonymous, the article says that Venice lost 24 centimeters in the last 100 years. At that rate, I'd say that it will be available to tourists for the remainder of your mother's life, if not much longer.
