The wave of gaudeamus celebrations and unified networks by Saturday’s test has not yet passed today, as well as yesterday for something else Piazza San Marco in Venice is completely invaded by high tide. If anyone had understood that the Mose works and that we have solved the high tide problem in Venice, it is out of the way, but bad.
First it was decided that now the Mose will no longer rise from extraordinary tides of +110 centimeters, but only when the forecast exceeds +130 cm. The difference of 20 centimeters for a city like Venice is abysmal, so much happens between his life and his death. In fact, if with a tide of +110 cm it passes below more than 11% of the city, with +120 cm it drops below 50% of Venice (San Marco included, of course), until almost 70% for a tide of +130.
So for now and we won’t know until, as Supervisor Cinzia Zincone announced, the Mose will be completely useless and will not be able to limit the water to +129 cmIn other words, 70% of Venice will be submerged exactly as before. Whenever there are high tides, like yesterday and like today, Venice will inevitably sink.
But at least we will intervene in exceptional tides, those higher than 130/140 cm, it will be said. But all this can be seen because easily on such devastating tides Very harsh sea and wind conditions are also combined, (which fortunately did not occur on Saturday) conditions in which the Mose He never did even a test. And, looking at the state of the drawers and gaskets, one understands why and one wonders who will take responsibility for giving the order to erect 78 half-rusted doors in front of the fragile Venice.
But for the public opinion on Saturday the Mose worked, to see certain TV services it seems that the most unsuccessful work in the history of Italy has become a resounding success. Too bad we don’t even know when, for example, the “control room”, the super-tech heart that commands the Mose, will be completed. There are those who say in six months, that in a year, the fact is that now, even in the amazing success of Saturday, we even had to trust the armyThanks to the Military Engineers who made their radio links available; otherwise, there is no test gateway.
All this without taking into account that all of the chronic and probably unsolvable problems of the Mose are all there. None have been solved: corrosion, the impossible cleaning of the seabed gates, the natural instability of the seabed. Not to mention the mystery of who will have to carry the burden of managing work to the biggest problem of all: Operation and maintenance costs. If we want to evaluate a work in comparison with the others (no country in the world with problems identical to those of Venice has chosen the Mose system to defend itself, but they have all opted for floating barriers) we must evaluate the costs (6 billion, at least , spent) and 100/200 million (nobody knows) a year for maintenance. Other similar systems in Northern Europe they solved the problem with less than half the resources and time. An Italian hit.
