In Venice, the hydrological officer is an important figure second only to the governor. What he said is the law of the lagoon. Since 1501, the Republic of Venice has used all available resources and technologies to maintain the ecological balance of the lagoon.

Now because of the construction needs of the Moses plan, this department is assigned to the New Venice Group by the mayor to assist them in completing the construction of the dam.

In public speaking, Moses' plan was to separate Venice from the Adriatic Sea to ensure that the flood would not continue to damage the city, but just now Marcusa told Pomona that it was a problem of rainfall, just as she said she It was Mrs. Prince, who did not say she was Linda Smith.

The hydrological data of Pomona in recent decades is impossible to touch, but in this forgotten library there are materials left by the former Venetian Hydrological Management Association. Perhaps Napoleon thought that these hydrological materials were related to the Knights Templar Whereabouts don't matter.

During the 14th to 16th centuries, when the massive silt carried by the Brenta, Gila, and Piaf threatened Venice, hydrographers ordered the diversion of the three rivers.

In this way, less silt was poured into Venice, and less water. Italy has a Mediterranean climate. The characteristics of the Mediterranean climate can be summed up as less rain in high temperature periods and more rain in low temperature periods. In 1966, the flooded sea in Venice was 200 centimeters higher than the Adriatic Sea. That is to say, the Moses plan, which cost 4.5 billion euros, could not solve the flood problem in Venice.

Housewives who often wash vegetables know that if the sewer is blocked by vegetable leaves, the speed of sewage discharge will be very high. If the water continues to pour in, the water will increase, so there is a kitchen garbage crusher. , to ensure that the drain pipe is not blocked.

In order to allow the sewage in the city to be discharged smoothly when the tide rises and falls, the three outlets of the Adriatic Sea cannot be too large or too small, and all cargo loading and unloading is carried out in the ports of Lido and Pola.

However, after the collapse of the Republic, the unified management method for the lagoon was also destroyed. Napoleon, the Austrian and Italian governments all introduced new systems. The Austrians excavated savagely, widened the entrance to facilitate loading and unloading, and drove the boat into the lagoon. .

Italy backfilled one-third of the lagoon for agriculture and fishing. In 1917, the Magra Industrial Zone was created. In order to allow cargo ships to enter the port, a Magra Canal was dug.

The industrial zone is not on the main island, but on the mainland. This place involves the employment of many people.

In 1973, Italy promulgated a special protection law for the lagoon, and all actions to reduce the area of ​​the lagoon must be stopped, which means that no one wants to fill the lake for agriculture.

Tourism is the pillar industry of Venice. In the past, there were no cargo ships coming in at the widened entrance, but there were more giant cruise ships coming in. The gondola boatmen have complained about this for a long time, and they even blocked the Giudecca Canal with small boats to prevent those The big ship passed by.

The centralized Republic of Venice is gone. How to manage the lagoon will involve the opinions of nine cities, different policies, their own economic interests, and national interests such as airports, railway stations, and museums. , must be restricted by people everywhere.

for you.

Pomona glanced at it in her busy schedule, and it turned out to be a rum ice cream sprinkled with chocolate chips.

Why are you here? Pomona asked.

I don't think it's better not to be a light bulb, Alessandro said. Besides, I don't like reading.

A place like a library is like a duck to water for a bookworm, and the snotty one forgets everything when he has a book.

She looked at the clock, and it was past six o'clock. Venetians usually eat early, so it was time to call him for dinner.

What are you looking at these hydrological data for? Alessandro asked.

Find the real cause of lagoon flooding.

So did you find it? Alessandro asked.

No. She said blankly, but she understood one thing, there was a person who really wanted to save the city.

If the population continues to drain, Venice will also become an empty city, and through the construction of the Moses Project, some large ships cannot enter, protecting the silt layer of the lagoon from being impacted by those large-displacement cruise ships.

In the old photos of Venice, there are many crooked towers. They are different from the Leaning Tower of Pisa, and they are the towers of the church bell tower.

The Leaning Tower of Pisa was originally said to be designed as a bell tower, but when the bell tower was built to the fourth floor, it was found that the bell tower had tilted to the southeast due to uneven foundation and soft soil, so the project was suspended.

When the project continued again, marble was used for the first time. This kind of stone is relatively heavy. The builders took various measures to correct the inclination. The upper floor of the bell tower was deliberately built with an inclination in the opposite direction to compensate for the deviation of the center of gravity that had occurred. But when it reaches the seventh floor, the tower body is no longer straight, but concave. Work was suspended again.

After almost a century of stagnation, the clock tower made its last push toward completion, another architect adapting the plumb line and making one last major correction. There were 7 bells in the 8-story bell tower when the top floor where the clock was placed was completed, but the bell tower was always in danger of collapsing and never struck.

In order to achieve a perfect balance, people in the Renaissance performed many precise and complex calculations and accomplished miracles unimaginable by ordinary people. Baroque architecture is very complicated and unnecessary, just like the machines designed by Da Vinci, full of imagination Powerful, but not entirely practical, not as efficient and fast-paced as it is now, but full of luxury and beauty.

People spend a lot of time and energy on one thing, and one day quantitative changes will lead to qualitative changes. It was also on this tower that Galileo completed the experiment of two iron balls falling to the ground at the same time.

The river can bring in silt, and it can also replenish the silt lost in the lagoon. This city is like a hydrological machine that has been calculated with great precision. A small change will cause unpredictable consequences, or it is a balanced balance, and a little weight will be added. Make it unbalanced.

People who work hard look so attractive that the snotty face of the snot man looks handsome.

Ahem. Alessandro coughed, attracting the attention of both of them.

Are you going to visit the Governor's Palace at night? He asked, We'll go after dinner.

I'm fine, how about you? Severus asked.

Me too.

Very well, let's go, said Alessandro briskly.

Where's your cousin? Severus asked.

Gianluca will take her home.

You should protect your sisters, Severus said sternly, especially those of unknown origin.

I've known Gianluca since I was a child...

But he hides very deeply, you shouldn't underestimate him, call them and let's go.

Alessandro reluctantly had to leave.

Who do you think that kid is?

A clever Muggle. Severus sighed. So many people despise him, and no one knows he's rich.

Weird. Pomona closed the book, made a copy with the Duplication Charm, and put the original back on the shelf.

There is a sick game in Venice, which is to bet on which tower will fall, but everyone knows not to bet on St. George's Church, because it will not fall from 1592, but it looks very strong The bell tower of St. Mark's Basilica fell first.

This is such a strange and unique city, no wonder someone is going to save her with 4.5 billion euros.
