Cities have a great characteristic, that is, high population density, once the occurrence of heavy rainfall such serious weather disasters, then lead to the consequences will be very serious.
If the city suffers from heavy rainfall, then the traffic is paralyzed for sure, and then it may also lead to power cuts and water cuts and other situations that affect normal life, and even serious cases of personal injury or death may occur.
One, the traffic paralyzed.
This is very good to understand, and this Luohe heavy rainfall we all see, the first thing that happens when the storm is the city's transportation system. Because the rainfall is too big and too fast, the city's drainage system can't keep up with the speed, so it leads to the accumulation of rainwater on the road.
City roads under heavy rainfall immediately become rivers, no wonder the majority of netizens will have a funny saying that finally know why they buy a car to pay boat tax.
More often than not, drainage systems in particular can't keep up with the rate of precipitation, and it can take days for traffic to return to normal during a rainstorm.
Two, normal life is affected.
Heavy rainfall is very likely to lead to power outages, which everyone should have experienced. The distribution of wires in the city is too dense, especially some street lamps and so on, due to the perennial exposure, there will inevitably be line aging problem. In the event of a rainstorm, these aging lines can lead to short circuits at any time, and even the occurrence of burned lines.
As for water cuts, this is understandable. Although the use of water and electricity has no direct relationship, but the power outage for a long time will certainly stop the water, because the operation of the pump needs electricity to drive, no electricity pump can not move naturally also stop the water.
Three, casualties.
The most frightening thing is this one, due to the safety hazards caused by heavy rainfall, it is likely that casualties will occur. Just like this heavy rainfall, Henan has already had 12 deaths, it's scary to think about.
Heavy rainfall will lead to serious waterlogging of roads, pedestrians may be drowning accidents; heavy rainfall will also lead to building collapse accidents, at any time may be dangerous to the safety of passers-by; heavy rainfall will also lead to electrocution accidents, passing through which leakage of electricity in the area may be electrocuted to death.
As for other less common accidents, that is also anyone's guess. There are so many problems that can be caused by natural disasters that humans seem very small in its presence.
The danger of strong rainfall is much greater in cities than in sparsely populated rural areas. I remember one year when we had heavy rain here, one underground store was flooded as a whole, and the traders suffered heavy losses, even some lost their homes. Although there were no casualties, we could not afford such financial losses. For ordinary people like us, any disaster is fatal.
