There was a barbecue in Xinbei, Taiwan Province, and a sudden flash flood caused people to evacuate in a hurry. What are the factors that cause flash floods?

A barbecue restaurant in Xinbei, Taiwan Province was hit by flash floods, and people had to evacuate urgently. There are many factors leading to flash floods. First of all, it may be the terrain, and the local forest coverage rate is not large. The most important thing is the water source condition.

On September 1 1, Beijing time, people from Taiwan Province province barbecued in Dabaoxi area. It is said that the people who participated in the Mid-Autumn Festival celebrations were all professional rescuers, and later they were criticized for making the worst demonstration. They came here for a barbecue that day, but in the middle of the barbecue, it suddenly rained heavily in the mountains. The water in the whole river soared rapidly, but all of them were professional rescue teams, so they quickly evacuated to safety without causing casualties. After this video was posted on the Internet, it caused a heated discussion, because as a professional rescue team, they actually chose to barbecue on the river, and it was during the rainstorm. Because of the powerful mountain torrents, all their barbecue utensils were washed away. Someone tried to rescue them, but they were dissuaded by the people next to them. After all, human life is more important, and the above three factors are the causes of flash floods.

Some people in Taiwan Province province suffered flash floods during barbecue, but all of them have been evacuated to safety. There are many mountain torrents, first of all, the terrain and forest coverage.

The main cause of mountain torrents is topography, because the drop will cause a lot of water to rush down together, which is very powerful. If it is serious, the flood may be mixed with many stones, which will cause fatal damage to the vegetation downstream and people in the river. At the same time, the forest coverage rate is also an indirect reason. If there is insufficient forest coverage in some places, it is easy to cause flash floods. The factor of flash floods is also the water source condition, because most flash floods come from precipitation.

Don't stay in the middle of the river when it rains, it is easy to collapse. If there is insufficient forest coverage in some places and heavy rain occurs, the risk of flash floods will increase. Fortunately, the flash floods in Taiwan Province Province did not cause any casualties, and we also warned people not to barbecue in the middle of the river on rainy days.
