How Fast is Venice Sinking?

According to a recent study, Venice is sinking at a rate of about 1-2 mm per year. While that may not sound like much, it’s enough to cause serious problems for the city in the long run. Learn more about the study and its findings here.

How Much Venice is Sinking?

Every year, Venice sinks about two millimeters. That might not sound like much, but it adds up. In fact, Venice is sinking so fast that it could be entirely submerged by the end of the century. Scientists have been trying to figure out why Venice is sinking for years, and they’ve finally come up with an answer.

The rate of sinking

Venice is currently sinking at a rate of about 2-3 mm per year. This may not seem like much, but over time it can add up to significant amounts. For example, the city has sunk about 10-12 cm since the start of the 20th century.

The rate of sinking is thought to be caused by a combination of natural and man-made factors. On the natural side, Venice is built on a foundation of soft clay that is slowly squeezed by the weight of the city. In addition, rising sea levels are putting additional pressure on the city’s foundations.

On the man-made side, Venice’s canals and buildings are constantly being pumped full of water in order to keep them from flooding. This water is also thought to be contributing to the city’s sinking.

While the rate of sinking may seem worrisome, it’s important to remember that Venice has been slowly sinking for centuries and it is still standing today. In addition, there are plans in place to help slow down and even stop the city’s sinking. For example, the MOSE project is an ongoing effort to build a system of barriers that will protect Venice from rising water levels.

The causes of sinking

Venice is built on 118 small islands located in a shallow lagoon in the Adriatic Sea. The islands are situated on the edge of a large underwater delta created by two rivers, the Po and Piave, which flow into the lagoon from the north. For centuries,Venice has slowly been sinking into the mud on which it is built. There are many causes of this slow sinking.

At its foundation, Venice is built on porous limestone and clay. The weight of the buildings presses down on this soft foundation, causing it to compact and sink lower over time. Groundwater extraction is also a significant factor in Venice’s slow sinking. As water is drawn out of the ground, it creates voids that cause the ground to sink further.

Climate change is also exacerbating Venice’s sinking problem. Rising sea levels are causing flooding in the city more frequently and with greater intensity. As a result of all these factors, it is estimated that Venice is currently sinking at a rate of about 1-2mm per year.

How Will Venice Sink?

The effects of sinking

Sinking happens when the ground underneath a city starts to compact. This can happen naturally, as happens in many old mining towns, or it can be the result of human activity, like when people pump water out of the ground faster than it can be replenished. Sinking also happens when the ground water underneath a city is drained for drinking or other uses. This is called groundwater depletion.

Venice, Italy, is slowly sinking into the Mediterranean Sea. The city is built on 118 small islands and is made up of more than 400 bridges connecting those islands. Venice has been sinking since it was founded more than 1,500 years ago.

The process of sinking is called subidence, and there are three main causes of subidence: compaction, groundwater depletion and loading.

Compaction happens when the sediments that make up the ground are compressed by the weight of buildings or people on top of them. This happens naturally over time, but it can be accelerated by human activity like farming or construction.

Groundwater depletion happens when people pump water out of the ground faster than it can be replenished by rain or other water sources. This can happen naturally if there’s a long drought, but it’s usually caused by human activity like watering crops or using city water supplies.
Loading happens when something heavy is placed on top of the ground, like a building or a parking lot. This puts additional pressure on the sediments and can cause them to compact over time

The potential for disaster

The potential for disaster is real. If the city sinks too much, the foundations of buildings will start to crumble and the city could be lost forever.

A study in 2014 found that Venice is sinking at a rate of almost 2mm a year. In the last 100 years, it has sunk by almost 20cm (8in).

If nothing is done to stop the sinking, the city could be lost forever within a few centuries.

What Can Be Done to Save Venice?

Venice is a city that is loved by many. It is known for its canals and romantic atmosphere. What many people do not know is that Venice is sinking. In this article, we will discuss how fast Venice is sinking and what can be done to save it.

The options for saving Venice

1. Build a New Venice: This option would involve building a new city next to the current city of Venice. The new city would be designed to accommodate the rising sea levels, and once it is finished, the old city of Venice would be abandoned.
2. Create a Barrier: Another option for saving Venice is to build a barrier around the city. This barrier could be made of concrete walls, or it could be a natural barrier such as a coral reef. The barrier would protect the city from flooding.
3. Move the City: A third option for saving Venice is to simply move the city to a new location. This would be a massive undertaking, but it would ensure that Venice does not disappear beneath the waves.
4. Do Nothing: Some people believe that we should do nothing to save Venice. They argue that the city has been sinking for centuries and that it is simply a natural process. They believe that we should accept that Venice will eventually sink and that there is nothing we can do to stop it.

The most likely option for success

One of the most likely options for success in saving Venice from sinking is to build a series of flood barriers around the city. These barriers would work to prevent high tides and storm surges from flooding the city, and they would also help to support the city’s foundations and prevent them from eroding. There are a number of different designs that have been proposed for these kinds of barriers, and it is estimated that they would cost around $6 billion to build.
