China: The floods suddenly turned bad, revealing the "culprit" that caused the floods to cause serious damage
China National Meteorological Center has raised flood warnings to level 3 in some of the country's western provinces, after sudden bad weather changes, according to the Xinhua News Agency.
According to forecasts, extreme rains will fall on areas in the provinces of Gansu, Ningxia, Shaanxi, Shanxi, Hebei, Liaoning, Yunnan, Guangxi and Sichuan in the West. China.
In some places, there is a possibility of rainfall over 70 mm / hour, accompanied by thunderstorms, dangerous strong winds.
The Chinese Ministry of Water Resources issued orange flood warnings in areas in Sichuan, Shaanxi and Gansu.
The local authorities above have recommended people to raise their guard against floods, landslides and mud floods. Outdoor activities in areas prone to natural disasters are completely banned until further notice.
In Sichuan, floods and rains have displaced more than 60,000 people in Sichuan. 31 rivers in this province exceed flood warning levels.
Since the beginning of June, severe flooding in China has occurred in the southern provinces, leaving more than 219 people dead, 31 million affected and economic losses amounting to 25.78 billion USD.
In Chinese history, floods have always been the most damaging natural disasters.
There are many causes of bad floods in China, including factors such as climate, topography and population distribution, according to CGTN.
1. Climate
China has 5 climatic zones. Most of the eastern and southern regions of the country are located in a tropical, subtropical monsoon climate. This causes the climate in these regions to become hot and humid, causing frequent heavy rains lasting from May to September, increasing the possibility of large floods.
This year, rainfall in Southeast China is already significantly higher than in previous years. In the Yangtze River basin, the average rainfall this year is the highest in 60 years, making floods worse.
2. Topography
China's topography is made up of highlands, plains, basins and hills. Chinese terrain is taller in the west and lower in the east, like a three-step staircase.
According to the China Bureau of Meteorology in 2012, about 738,000 square meters of land, including most of the southern and eastern regions of China, are well below the flood levels of rivers flowing through the delta. During the flood season, these areas are prone to flooding.
3. Distribution of population
If you draw a line from Hebei city, Heilongjiang to Dang Chong city, Yunnan, you will easily see a line called "Duong Ho" appear on the map. This "Duong Ho" consists of rivers and lakes of large and small successive.
China has a history of agriculture for thousands of years. Since ancient times, the Chinese have depended on agriculture. Living close to large rivers and lakes ensures fertile crops with abundant water resources and fertile soil. Therefore, in China, the provinces with large rivers and lakes always attract many people to settle.
Cities with populations of more than 10 million, including Shanghai, Chongqing and Guangzhou, are all located east of "Lake Road". This is home to tens of millions of people and has great economic significance.
However, the construction close to the river bank makes the area of riverside lagoons lost, flood water therefore flows more rapidly, easily overflows into urban areas and causes serious damage.
