Heavy rain swept through New York, and the subway station became a water curtain hole , what is the

This heavy rainfall has caused New York to be almost paralyzed, mainly because of its low-lying geographical location. So in the process of this rainfall, a lot of rainwater has flowed into it, and their subway is currently in a state of suspension. Water can be seen everywhere on the road surface, reaching up to the waist.

Today we will take a look at the local drainage system in this precipitation? <>

First, the drainage system is already in full operation.

After the hurricane arrived in New York Week, the local area has entered a state of first-level alert, and the city's drainage system has begun to operate at all, but there is no way to drain the current water, on the one hand, because of the terrain, on the other hand, the precipitation this time is indeed very heavy. At present, the amount of precipitation in one hour has exceeded 80mm. It has set a new record for local rainfall, so it is simply not possible to rely on local drainage facilities to accomplish this task.

Second, what do you think of this rainfall?

This rain has caused irreversible damage to New York, on the one hand, most of the municipal construction is basically ineffective, and on the other hand, because many places are in disrepair and the electrical circuits are aging. So far, more than 5,000 households have been without water and electricity, and according to the latest situation, this number is likely to continue to increase in the future. <>

Third, why are cities so weak in the face of heavy rains?

In fact, the main reason for this is that with the large-scale gathering of population, the land where we live will be transformed. But in the process of feeling, the water storage capacity of the land will be reduced, because most of the places will be covered with reinforced concrete, and in this case, the water will form a flow on the surface of the earth, and then collect it together, instead of being absorbed by the land and flowing underground. So that's why once there is heavy rainfall in megacities, urban waterlogging will occur.

In fact, the local drainage system is particularly good, but because the heavy rain is too heavy, it will cause the subway station to be blocked.

The local drainage system is not very good, and netizens have complained about the disrepair of the New York subway, aging facilities and other problems, and waterfalls and fountains appear in many places inside the subway station, so to speak.

The local drainage system is very bad. If the local drainage system is good, the subway station will not become a water curtain hole, and the drainage system of a place is very important, if the drainage system is not good, it is very easy to cause flooding.

<> is certain that there must be some problems with the drainage facilities in New York City, otherwise it would not have been paralyzed by 80mm of rain in an hour, and so far, the roads in New York City have been invisible from the roads, and the subway has been flooded. The whole city is almost paralyzed, and this time the precipitation has affected New York City more than any previous flood, and today we will take a look at this disaster. <>

First, whether there is a problem with the drainage system.

The reason I decided there was a problem with the drainage system was because the ground in New York was already flooding before the precipitation began. In particular, the drainage facilities in the subway system, and even some equipment are not working at all, because in the whole process of precipitation, the subway in New York is the first place to be flooded, although its terrain is relatively low, but it is generally the highest level of safety. Logically speaking, it should not have been overrun by the flood so quickly.

Second, the intensity of the precipitation this time.

When discussing the issue of urban drainage, we can't ignore the intensity of precipitation, as the heavy precipitation in New York City has been snorting so far, their 100-year record reached 80mm per hour, and now the precipitation is about 40mm per hour. In terms of precipitation, this is understandable. <>

Third, how to improve a city's drainage system.

In fact, for a city, the most advanced drainage system is the land, but with the process of urbanization, most of the land is replaced by reinforced concrete, so after the precipitation reaches the ground, there is no way to be absorbed, which forms the water flow. In the process of urban renewal, the water will flow to lower places, so it will cause serious flooding. In fact, many countries want to solve the problem of urban waterlogging, but as long as it is a country with a monsoon climate, there is basically no good solution.

There is indeed a certain problem with the drainage system, which has completely collapsed and is completely unable to withstand the arrival of this rainstorm.

This does not indicate that there is a problem with the local drainage system, because the amount of precipitation brought by the hurricane is so large that it far exceeds the carrying capacity of the local drainage system.

There is indeed a certain problem with the local drainage system, which is why this situation occurs.

Affected by "Ida", New York City was hit by torrential rains, which caused flooding, flooding the subway, turning the subway station into a curtain hole, and passengers trying to leave. The flooding of the New York subway once again exposed the vulnerability of the subway system in the face of extreme rainfall.

I think extreme weather is caused by human destruction, but now there are many extreme weather in many areas, such as high temperatures, heavy rains, and floods.

It may be that the ecological environment has been damaged, the soil is not strong, and there are not too many trees, which will lead to a lot of natural disasters.

The global climate has changed, and there is a trend of global warming; Environmental pollution; The global environmental destruction and various felling of plants have led to an increase in solar radiation and a resurgence of the greenhouse effect.

The occurrence of bad weather has caused many people to encounter some problems in their travel. In our country, there are also heavy rains in many places, so most people will choose to take public transportation when traveling. But what we didn't expect was that New York, USA, was hit by torrential rain, and the subway station was flooded.

This is also something we didn't expect, you must know that New York is a very prosperous city in the United States. And most people are very eager for this place. However, in such a prosperous place, there is a situation of stagnant water backfilling, which is also unacceptable to everyone.

The drainage system must be taken seriouslyIn the event of heavy rain in the city, everyone must reduce travel and pay attention to their own safety. And this time, the New York subway station can be said to have directly become a water curtain hole, and passengers cannot walk normally in the subway station, but can only grope in the water. At that time, the stairs of the subway station were all waterlogged, and the water was flowing down all the time.

This situation also makes many people say that such a prosperous city is not as good as a random subway station in our country.

It is because the United States has not maintained and repaired the local drainage system for a long time, which is why there is a backflow of water during heavy rainfall.

The subway drainage system is designed to drain only inches per hour (38 mm). Therefore, for this subway flooding, New Yorkers may have become accustomed to it, just complaining and ridiculing.

This is due to the fact that the local drainage system is in disrepair and the rainfall is very heavy.

New York was hit by heavy rains, the city was seriously waterlogged, and the subway station was flooded, and the local drainage system should have hidden dangers from the local water situation。However, the local transport department said that the drainage system was operating normally, and the reason why there was a large amount of water was because the terrain of the place where the water was accumulating was relatively low, and it was normal for water to flow to the lower places. I have to say, the explanation of the New York Transportation Department is perfect!

It seems to make a lot of sense.

Facts speak louder than words, some places are very high, and there is also a large amount of stagnant water, and it is difficult for people to travel an inch! It is reported that the reason why the water in New York is very deep this time is mainly due to the heavy rain! The heavy rain was due to the impact of Tropical Storm Elsa.

It is reported that when the rainstorm is in full swing, the weather forecast only issues a warning, and it can be said that the warning of extreme weather is still a step slow! Now the city is still a sea of water, the drainage system is normal, I don't know why there is still so much water.

Traffic paralysis is due to the fact that most of the subway stations are very waterlogged, and some of the flooded subway stations have stopped operating. The subway stations that are still in operation have very deep water, and some even reach the waist level. The people of New York, USA, said that when they were catching the subway, they were brutally treated by the subway staff, which was terrible!

You have to go to work in a rainy day, and when the water is serious in a rainy day, there is no tolerance for catching the subway, and most of the people in New York say that it is simply unbelievable!

This time the water in New York City should be the largest in history! At that time, the local transport department said that it was doing its best to drain the water! Full efforts are underway to restore normal transportation, etc.

The Transport Department advises people not to go to work for the time being and wait for everything to return to normal.

Netizens are hotly discussing that the water in New York City in the United States is so serious that people can't travel normally, and netizens have said, is this the United States? Isn't the United States the most beautiful landscape? It's also become an ocean?!

New York was hit by heavy rains, and the subway stations in the city were heavily waterlogged, and the local drainage system should be a hidden danger.

There are hidden dangers, the most important thing is that if there is a heavy rain in this process, there will be a series of collapses, and now the local situation is also very serious, there is no way to carry out a reasonable control.

There is a hidden danger, and it is also possible that the local rainstorm has blocked the drainage system, so this flooding situation will occur.

Of course there is. The local drainage system does not discharge a lot of water, and there are many pipes that are blocked, which is a very serious safety hazard.
