Geography

Yellow River Yellow River in China, flows through seven provinces: Shandong, Shaanxi, Henan, Inner Mongolia, Qinghai, Ningxia Hui and Gansu.Yellow River can be divided into three parts: the lower, middle and upper reaches.The first is located on the Great Plains.Average - between the province of Shaanxi, and the Ordos Plateau.Upper - from its origins in the Tibetan Highlands to the Loess Plateau.Yellow River - one of the most full-flowing in the world.Pool of the Yellow River provides drinking, industrial and agricultural water to more than 140 million people.The bed it is extremely mobile and it often overflows its banks.Floods bring many disasters, that was the birth of the second name of the river - "The trouble is China."But there is also the opposite phenomenon, such as the 90-ies of the last century, the Yellow River is not just dry up completely in the northern regions.

floods on the Yellow River

For 3000 years, the Yellow River more than a thousand times out of its banks and 26 times changed its direction.To protect against flooding in the Yellow River built a lot of dams and diversion channels, which, however, do not change the situation on the river.Studies by American scientists showed that the construction is not stopped, not only the problem, but even provoke her as more than 3 million years, humans cover the natural history of the river.Waterworks slow flow of the river, thereby causing sedimentation at the bottom.As a result, the water rises again, and the power of flood times from time increases.People build even more powerful and deep dam diverting channels, but all the more intense the Yellow River overflows its banks.Such a struggle of man and the river could lead to unintended consequences.

history of the Yellow River

ancient map of the first rulers of China show that the Yellow River flowed north of its current channel.In 2356 BC, it happened in the flood of the Yellow River changed its course and began to fall into the Gulf of Giglio.After 2000 years, the river began to build diverting canals and dams, and she began to fall into the Yellow Sea.One of the military tactics of the warring dynasties were flooding the enemy troops, or its territories.So, at 11 AD flooding caused the fall of the dynasty of Xin.Also, the hydraulic structures were destroyed in the year 923 in order to protect the capital of the Liang Dynasty from the attack of the Tang Dynasty.From the second millennium AD Huanghe (Yellow River), she regularly broke through the dam.One of the severe floods occurred in 1887, it claimed 2 million lives.
