Massive Construction: Building a Billion Dollar Flood Defense System | FD Engineering

Massive Construction: Building a Billion Dollar Flood Defense System | FD Engineering
Extreme Constructions - Complete Series: • Extreme Constructions ...
The plan to build a surge barrier against the tides that cause the so called “Acqua Alta” has been underway for nearly forty years, but only now is the massive 7-billion-euro surge barrier nearing completion. This documentary looks at the engineering, construction and instalment of this huge and unique mobile dyke that sits invisible under the Venice lagoon, until high tides trigger it to rise from the sea bed to protect the ancient City of Water.
The last two stages of the construction of this enormous barrage involved placing the massive concrete underwater housing for the caissons that act as a barrier at the bottom of the lagoon entrance channels. The transport of the massive MOSE surge barrier and all its concrete and steel parts is a true feat of heavy lift technology and maritime engineering. Transporting the concrete beds required the customised construction of a catamaran that could be tugged over the exact location in the approach channels to the port of Venice, precisely identified using GPS while lowering the barriers involved a jack up tower which slowly sank them into place.
Today the system is fully operational. But only time will tell if this costly and controversial new maritime engineering solution to Venice’s nagging high water problem will actually work.

Looking forward to when mother nature humbles the engineers and the ones that ok'd this.

[@enricoiraldo9057]

Yes, in the end we were always humbled. For example, by nature we can’t fly, so nowadays it’s impossible to fly. Cardiovascular disease, cancer, infections are all natural, and in fact there is no way to cure them. Hell, we can’t breath underwater, and in fact oxygen masks were always a failure. I guess we should just all surrender to nature and leave until 30 eating grass and raw meat 😄

[@cestmoi1262]

If the sea level has risen over the last 100 years then why aren't the marshlands permanently under water by now.

[@justinmorgan2126]

The marshes are not static, they grow too. So long as there is not a catastrophic sea level rise the growth of the marshes in height can keep up with the rise in sea level. Buildings however don't increase their height naturally.

[@cestmoi1262]

@@justinmorgan2126 I guess Nature works in strange ways. The ground under marshes lifts up but the ground under man made buildings doesn't. Convenient, isn't it.

The earth will continue to have sea level rise. So regardless of how massive the barriers are, eventually they will become obsolete. Would it not be easier to RAISE Venice -or- float it ?

Estaria bueno saber como hacen para evitar que pase el agua entre las compuertas o por debajo de ellas. Es decir cómo es el sellado estanco final del sistema una vez elevada la barrera.

i'm pretty sure the canals of Venice way back in its early ancient days were road ways but since the city floods they dug the canals to reduce flooding but since it's sinking the flooding gets worse over time

[@ricmay2837]

How is it an environment fix … the city is unsafe ground … they may have to accept it’s time to move on…. To higher ground….

[@lavalamp6410]

A massive failure, when the barriers are raised silt accumulates in the cavity left making it impossible to lower the barriers again, that is if the corrosion on the hinges doesn't lead to catastrophic failure when they try to raise the barriers, or the massive growth of the marine mussels hasn't totally clogged up the workings. Then there is also the corrosion problem with the barriers waiting to be installed, because they started rusting from the salt laden air. I'm sure going into salt water was thought of by the designers

I totally agree, stop messing with mother nature, we should not be trying to change things to suite our life style. We build on the shores within two feet of high tide and then we are upset because our home was washed away and expect some one other then ourselves to bail us out of our own stuipidity.

Maybe technically correct but a bit misleading. Sea levels may be at the same level as they were 100,000 years ago but they have been fluctuating wildly in that time. We are just coming off one of the lowest sea levels in Earth's history. In the last 12000 years the average sea level rise is around 9mm per year, in the last 300 years it has slowed to around 4mm per year. To say it is a man made emergency is just not true..

[@DarthAwar]

@@bikepacker9850 it's not man made (as it's an ice age ending part of a natural cycle!) but man has accelerated it dramatically ironically its not co2 doing the damage but refrigeration gases, methane and the like doing the a majority of the long term damage not too sau co2 levels are not a very important part

The rate the ice is melting is far faster than previous natural cycles and the increases match exactly with the industrial era and so on. Not a coincidence.
