Another large issue with the piling method concerns the rising tides across the planet. This is something that the residents of this city have come to regard as a fact of life, and are not immensely troubled by it. Concerns about interference with normal tides can increase the levels of toxic chemicals, such as mercury, in the waters of Venice.
This could threaten the lives of both marine life and the health of the people who eat the local fish. Since Venice does not have sewers, most of their "household waste flows into the canals and is washed out into the ocean twice a day with the tides" Fletcher, So, there is no telling what effects the gates can have on the city's natural waste system. Environmental, Water Resources, Ocean, Geotechnical, and several other engineers are working hard to solve any potential problems with the project.
Some say that the project will be a total failure because it would have a negative affect on Venice. Then there are also those who say that this project will have a positive impact on the city. Since the project is rather new, and completion for the project isn't for another years, one will only be able to know the true impact of the project until it is put into effect. There are several professionals working on the project and since there are yet to be any true uncertainties with the project, construction will continue as normal.
Hopefully, the project can create a prospective future for the city of Venice. Retrieved from. Alley, W. Relly, and O. Fletcher, C. Flooding and environmental challenges for venice and it's lagoon: State of Knowledge. New York: Cambridge University Press.

Barriers and gates take shape to protect venice from the sea. ENR, 20 , Rubbish polluting lagoon venice italy. In the s a series of artisan wells opened across the city.
Having been built on a lagoon and surrounded by the salty Mediterranean Sea, the city had always struggled to find drinking water.
To service these wells, holes were drilled deep, past the piles and into the hard clay the piles were standing on. This disruption has dire consequences. By changing and weakening the structural integrity of the wood, the city began to sink at an increased rate.
The city was quick to stop once they realised the error of their actions, however, it was too late to undo the damage they had done. Today, the wells are banned across the city and no one is trying to drill into the ground. Another impact on Venice is erosion caused by boats in the canals.
Today there are double the number of motorised watercraft in the canals than ten years ago. These motorised vehicles create much more disruption and turbulence in the water than their rowed counterparts.
This water disruption is leading to increased rates of erosion on the already aging buildings. Today Venice faces a lot of problems, from erosion to rising sea levels, the city is working hard to ensure it stays for years to come. Why was Venice built on water? But how did they managed to do something like that?
Well, the ingenious Venetians used millions of oak poles. They planted the poles in the ground until they reached the solid land under the mud layer. The space between the poles was filled with shards, stones and other waste materials. Over the layer of poles they put wooden boards that formed the base. Over these boards Venetians built their houses.
Basically Venice is a huge pile dwelling. Impressive, uh? If you want to learn more about Venice you can read my post Venice names and numbers.
