Why is Venice, a "water city", short of water when the water level drops, rivers dry up and ships run aground?
As we all know, all the stars, such as the earth, the moon and the sun, are not static, but are always moving. Among them, the moon revolves around the earth and the earth revolves around the sun, which will produce a centrifugal force, but at the same time there is also a gravitational force between the moon and the earth, and between the earth and the sun. Centrifugal force and gravity will produce a resultant force under the mutual influence, which is the tidal force that causes the tidal phenomenon of seawater. The so-called tidal phenomenon refers to the periodic high tide and low tide of seawater, in which the seawater will have a high tide due to rising at high tide and a low tide at low tide.
When you are at the seaside, people's perception of the fluctuation of seawater is the most intuitive and obvious. Like Venice, a water city built by the sea, you can naturally feel the occurrence of tidal phenomena clearly. Some time ago, Venice suffered a very rare low tide. Because of this low tide, the water in Venice was decreasing, and then the river dried up and the ship ran aground. I guess no one thought of it. What do you mean? Shuicheng? Venice will one day fall into the dilemma of water shortage. After all, Venice has been facing the crisis of being submerged because of the rising water level.
The rapid development of society has caused great damage to the environment, and the emergence of greenhouse effect has led to the continuous warming of the global climate. For this reason, the ice sheets in Greenland and other places have melted, leading to sea level rise. Sea level rise has a great impact on the coastal city of Venice. The level of cities today is more than 20 centimeters higher than that of a hundred years ago. 1999, Venice was hit by a big flood, and the water level of this flood once rose to 1.87 meters. In addition, Venice suffered a flood with a water level as high as1.52m in February last year.
Venice? Born of water? And then what? Prosperous because of water? But it's the same? Is the water sleepy? . Due to the rising water level in recent years, Venice faces the dilemma of flooding every year. However, this sudden and rare low tide this year has made Venice, a water city, suffer from water shortage.
