Venice – Venice continues to drop into the sea. Why don’t you just pump the lagoon city up with salt water again? That is the idea of an engineer to save the place.
The plan is revolutionary. Engineer Enter Teatini wants the city in Italy Get air to breathe for two or three decades. To do this, he wants to raise the city’s level by 30 centimeters. This reports CNN.
Venice has dropped by almost 25 centimeters
Venice dropped by about 25 centimeters in the last century. And the average sea level is in the Tourists-Metropolis rose by almost 30 centimeters. Venice drops by about two millimeters every year, while the tides rise by about five millimeters.

Water trick is supposed to save the city
Teatini aims at the groundwater manager. This is a rock or sediment body that contains groundwater and runs up to 1000 meters below the surface of the earth. The idea comes from the observation of hydrocarbon reservoirs in northern Italy. There are reserves for winter by warehouses in which gas is pumped out of external pipelines and saved in summer.
The result: in summer, when the reserves are filled with gas, the country rises. In winter, while the reserves are used, the country falls off. Teatis idea: “Develop wells in which we inject water instead of removing it.”

Brunnen belong to the project
The project therefore includes a dozen fountain. These should be around the Sight be drilled. However, these wells must be installed in the lagoon. You are not allowed to More Or go under the mainland.
And how is the water prevented from climbing up? A thick layer of sound is used under the surface of the lagoon. And how does the water get into the ground? For this purpose, holes are drilled to the island. Then salt water is pumped through the pipes to lift the floor. When the water gradually flows into the groundwater ladder, the country rises around it.
A pillow made of water should be the solution
Why does this circle have to be so wide? According to Teatini, to achieve a “very flat, uniform buoyancy”. The recipe: to raise Venice on a water -bed -like pillow, while the country around it stays. It is a kind of fracking. In this process, liquids are injected into the earth under high pressure in order to crack surface rock layers so that it is then possible to access oil and gas reserves. Injection of liquids under high pressure can lead to tremors in the earth.
But the cracking of the layers definitely wants to prevent Teatini. That is why the height difference is limited to 20-30 centimeters.
