How did the Yellow River come about, and what the Yellow River was like

The source of the Yellow River is located in the hinterland of Qinghai. The source of the river is one for the Zha song, the second is about the ancient sect of the song, and the third is the Kari song. Zhaqu dries up most of the year, while Kariqu is the longest with five springs, and the basin area is also the largest, and it does not dry up in the dry season, which is the source of the Yellow River.

There is only one spring, which is an oval basin that is 40 kilometers long from east to west and about 60 kilometers wide from north to south, and there are more than 100 small water pools in it, which are like stars and pearls.

The gestation, birth and development of the Yellow River are subject to the geological processes in the geohistorical period, with the tectonic movement caused by crustal changes as the external force, and the erosion, transport and accumulation under hydrological conditions as the internal force.

In the course of the history of Chenghe, the movement has been continuous and advancing with the times. Soil erosion on the Loess Plateau and sediment accumulation in the lower reaches of the Yellow River have been going on since prehistoric geological times, and the impact of human activities has been increasing since then.

According to various studies, the PaleoYellow River has three stages of development: the Early Pleistocene from the Tertiary to the Quaternary is the gestation period of the PaleoYellow River. In the Middle Pleistocene of the Quaternary Period (1.15 million years ago and 100,000 years ago), the ancient Yellow River was born and grew in the period.

In the Late Pleistocene (100,000 years ago, 10,000 years ago), the Yellow River formed an ocean system.

During the historical period, the river course of the Yellow River in the upper and middle reaches of the plain has also evolved, and some of the changes are still great. For example, the Hetao section of Inner Mongolia, before 1850, it is mainly divided into two branches, the north branch is the main stream, the foot of the Yin Mountain is called the Wujia River, and the south branch is the Yellow River today. In 1850, the lower reaches of the Wujia River north of Xishanzui were silted up and cut off for about 15 kilometers, and the south branch became the mainstream, and the north branch became the retreat canal in the Houtao irrigation area.

The swing of the Longmen Tongguan river is also larger. However, the evolution of these sections has little impact on the development of the Yellow River as a whole. The course change of the Yellow River mainly occurs in the lower reaches.

Historically, the range of river changes in the lower reaches of the Yellow River has roughly reached the Haihe River in the north and the Jianghuai River in the south. According to historical records, the lower reaches of the Yellow River have flooded more than 1,500 times, and there have been more than 20 major diversions.

The name of the Yellow River is due to climate change, and people build a lot of construction, with the deterioration of the environment, a large amount of sediment on the Loess Plateau is lost into the Yellow River, the Yellow River has since become a turbid yellow soup-like appearance, at the end of the Warring States Period, the Yellow River has been called "Turbid River", the early Western Han Dynasty began to be called "Yellow River", to the Song Dynasty, this name has long been widely spread, accepted by the world.

The status of the Yellow River.

The Yellow River is one of the longest rivers in the world and the most important birthplace of Chinese civilization. Since ancient times, the Yellow River Basin has been pregnant with a splendid Chinese civilization, it is one of the most important rivers in China, its history is longer than any historical civilization in the world, although it has been changing for a long time, but it has always been the "feelings" of civilization.

History of the Yellow River.

More than 2,000 years ago, the water of the Yellow River was clear, recorded in many classics, and it was also mentioned in the "Book of Songs" that we are familiar with, that the Yellow River in that period was not called the Yellow River, let alone the Turbid River, and people called it only one word: "River".

The Yellow River is the second longest river in China and the fifth longest river in the world. The Yellow River originates in Bayan Kala Mountain in Qinghai Province, the Yellow River is turbulent and rushing all the way, and it is unstoppable, Yu Yafei's "Ode to the Yellow River" praises the spirit of the Yellow River: "The Yellow River runs through Changhong, and the waves are rushing and majestic; The stone barrier mountain screen is difficult to stop, and it always flows eastward for thousands of turns".

The Yellow River flows through nine provinces and regions, including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan, and Shandong, and flows into the Bohai Sea in Kenli County, Shandong, with a total length of 5,464 kilometers and a basin area of 10,000 square kilometers. The Yellow River and its coastal basins have had a huge impact on human civilization and are one of the most important birthplaces of the Chinese nation, and the Chinese call it the "mother river".

With a total length of 5,464 kilometers and a basin area of 752,443 square kilometers, the Yellow River is the second largest river in China after the Yangtze River. Because the middle section of the river flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is also known as the river with the most sediment content in the world. However, in Chinese history, human civilization along the Yellow River basin has had a great impact and is one of the most important birthplaces of the Chinese nation, so the Chinese generally call it the "mother river".

The Yellow River is the second longest river in China, the fifth longest river in the world, and the river with the highest sediment content in the world. The Yellow River flows through nine provinces and meanders through northern China. Looking down from the sky, it is very much like a huge "several" character, and faintly like the unique totem --- dragon of our nation.

The source is located in the Yaradazai Peak of the Bayan Kala Mountains in Qinghai, with a main stream length of 4,675 kilometers and an average flow of cubic meters per second, which flows into the Bohai Sea in Kenli County, Dongying City, Shandong Province. The dividing point between the upper and middle reaches is Hekou Town in the Inner Mongolia Autonomous Region, and the boundary point between the middle and lower reaches is Jiumengjin in Henan Province. The estuary of the Yellow River is 1,500 meters wide, generally 500 meters, only 50 meters in the narrower places, the water depth is generally meters, and the depth in some places is only meters.

The Yellow River originates from the Bayankala Mountains on the Qinghai-Tibet Plateau, and its main stream runs through nine provinces and autonomous regions: Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan, Shandong, and flows into the Bohai Sea. The annual runoff is 57.4 billion cubic meters, and the average runoff depth is 77 mm.

However, the amount of water is not as large as the Pearl River, there are 35 major tributaries along the way, the larger tributaries are in the upper reaches, there are Huangshui and Tao rivers, in the middle reaches there are Qingshui River, Fen River, Wei River, Qin River, and in the lower reaches there are Yi River and Luo River. The lower reaches of the Yellow River basin are small because of the lack of lakes on both sides and the high riverbeds, and the few rivers that flow into the Yellow River.

The Yellow River flows through Shandong, Henan, Shanxi, Shaanxi, Inner Mongolia, Ningxia, Gansu, Sichuan and Qinghai provinces.

The Yellow River is the second longest river in China, the middle and upper reaches of the Yellow River are mainly mountainous, the middle and lower reaches are mainly plains and hills, and the middle and lower reaches are mainly plains and hills, and the middle path is the Loess Plateau, so the sediment content in the Yellow River is relatively high. The Yellow River is the most important birthplace of Chinese civilization and is called the mother river by the Chinese.

Characteristics of the Yellow RiverThe main characteristics of the Yellow River are a lot of sediment, and the soil erosion in the upper and middle reaches of the Yellow River is very serious, resulting in serious siltation of the lower reaches of the river, and the riverbed is raised by about 10 centimeters per year on average. The average sediment transport volume of the Sanmenxia Station of the Yellow River is about 1.6 billion tons for many years, and the average sediment volume is 35 kilograms per cubic meter, ranking first among the major rivers and unique among the rivers in the world.

The Yellow River originates in the ancient Zonglie Basin at the northern foot of Bayankala Mountain on the Qinghai Plateau, meanders eastward, crosses the Loess Plateau and the Huang-Huai-Hai Plain, and flows into the Bohai Sea. The total length of the main stream is 5,464 kilometers (more than 10,000 miles), and the water surface difference is 4,480 meters. The total area of the basin is 10,000 square kilometers (including the area of the inflow area is 10,000 square kilometers).

Overview of the Yellow River Basin The Yellow River Basin stretches from Bayan Kala Mountain in the west, the Bohai Sea in the east, the Qinling Mountains in the south, and the Yinshan Mountain in the north, with a basin area of 10,000 km. The Yellow River originates at the northern foot of Bayan Kala Mountain on the Qinghai-Tibet Plateau, flows through 9 provinces and autonomous regions including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong, and flows into the Bohai Sea in Kenli County, Shandong, with a total length of about 5,400 km. From the source of the river to Tuoketuo in Inner Mongolia, most of the areas above Lanzhou are well covered with plants; The main stream from Maduo to Qingtongxia has many canyons and is rich in water and energy resources; Below the Qingtong Gorge is the Hetao Plain, which has developed irrigation and is navigable.

Tuoketuo to Taohuayu in Henan Province is the middle reach, and there are also abundant water energy resources; The two banks are the Loess Plateau, with little vegetation and serious soil erosion, which is the main sediment of the Yellow River. Taohuayu to the mouth of the river is the downstream, most of the embankments on both sides of the bank have been built, and the sediment accumulation makes the riverbed generally 3 5m higher than the ground on both banks, and the more reaches 10m, so it is called the hanging river; There are many irrigation areas along the coast, and the main stream is also navigable. Near the estuary, the Yellow River estuary channel is constantly silted, extended and diverted, and has a strong land-building effect.

There are 10 tributaries with an area of more than 10,000 km that directly flow into the main stream in each river section, with the Wei River having the largest area and water volume.

The Yellow River Basin is so long, and whether the water is yellow or not depends on different river basins. At the source of the Bayenkola Mountains, the water is still very clear, and after passing through the Loess Plateau, the water turns yellow and extends downstream. In recent years, after the construction of the Xiaolangdi project of the Yellow River, the water quality in the lower reaches has been improved to a certain extent, and it is no longer completely yellow, but in general, the sediment in the water is still relatively large, and the overall color is still yellow.

It is said that a long time ago, there was a Huangjiazhuang in the upper reaches of the Yellow River, and a girl named "Yellow River" was forced to death by bullies. When her family heard that she had committed suicide by throwing herself into the river, they sailed down the river to find her body, calling her name along the way. Hence the name "Yellow River".

It's just a folklore. In fact, more than 2,000 years ago, the Yellow River was simply called "river". At that time, the river was still very clear.

There is still a lot of forest vegetation in the upper reaches of the Yellow River and in the Shanxi and Shanxi regions. In Xi'an, there is a saying that "eight rivers surround the capital", which shows that the Loess Plateau was still rich in grass and water at that time. It is only due to climate change over the past millennium, as well as wars, construction projects and deforestation, that the environment has deteriorated.

A large amount of sediment on the Loess Plateau was lost and poured into the Yellow River, which caused it to be so turbid today, so the people on both sides of the river gradually called it the "Yellow River". The ancients said: "The Yellow River is clear, the world is peaceful", and I hope that one day after unremitting governance, the Yellow River can remove the word "yellow" again.

In the past, the Yellow River, like other rivers that had not been affected by human influence, was very clear and did not form an "above-ground river" downstreamNowadays, the Yellow River has a turbid flow and a huge amount of sediment, and these sand slowly precipitate when the water speed slows downstream, causing the riverbed to rise, gradually forming an "above-ground river" with a higher river height than the surrounding environment

In terms of geological conditions, the vast majority of the Yellow River Basin is the Loess Plateau, and the basic geological process is to move mountains and reclaim the sea, scouring the Loess Plateau and shaping the North China Plain. The function of the Yellow River is to transport water and sediment resources from the basin to the North China Plain and the sea. Therefore, the natural conditions of the Yellow River determine its siltation process, and also determine that it must be an above-ground river, and the reason for this change is the result of soil erosion caused by the endless destruction of forests and fields by human beings.

It used to be clear, but due to a large amount of human reclamation, the Yellow River has become what it is now.

You can time travel a bit, you know. (o (o just kidding) you can google it, there should be.)
