The '''Yellow River''',{{Efn|{{lang-zh|s=黄河|t=黃河|p=Huánghé}}}} also known as '''Huanghe''', is the second-longest river in China and the [[List of rivers by length|sixth-longest]] river system on Earth, with an estimated length of {{Convert|5464|km|mi|abbr=on}} and a [[Drainage basin|watershed]] of {{cvt|795000|km2|sqmi}}. Beginning in the [[Bayan Har Mountains]], the river flows generally eastwards before entering the {{Convert|1500|km|mi|abbr=on}} long Ordos Loop, which runs northeast at [[Gansu]] through the [[Ordos Plateau]] and turns east in [[Inner Mongolia]]. The river then turns sharply southwards to form the border between [[Shanxi]] and [[Shaanxi]], turns eastwards at its confluence with the [[Wei River]], and flows across the [[North China Plain]] before emptying into the [[Bohai Sea]]. The river is named for the yellow color of its water, which comes from the large amount of sediment discharged into the water as the river flows through the [[Loess Plateau]].<ref name=":022">{{Cite book |last1=Mostern |first1=Ruth |title=The Yellow River: A Natural and Unnatural History |last2=Horne |first2=Ryan M. |publisher=Yale University Press |year=2021 |isbn=978-0-300-23833-4 |pages=58 |jstor=j.ctv1vbd1d8}}</ref>

The Yellow River basin was the birthplace of [[Yellow River civilization|ancient Chinese civilization]]. According to traditional [[Chinese historiography]], the [[Xia dynasty]] originated on its banks around 2100&nbsp;BC; [[Sima Qian]]'s ''[[Shiji]]'' ({{circa|91&nbsp;BC}}) record that the Xia were founded after the tribes around the Yellow River united to combat the frequent floods in the area. The river has provided fertile soil for agriculture, but since then has flooded and changed course frequently, with one estimate counting 1,593 floods in the 2,540 years between 595&nbsp;BC and 1946&nbsp;AD.<ref name="Treg" /> As such, the Yellow River has been considered a blessing and a curse throughout history, and has been nicknamed both "China's Pride" and "China's Sorrow".<ref>Cheng, Linsun and Brown, Kerry (2009) ''Berkshire encyclopedia of China'', Berkshire, p. 1125 {{ISBN|978-0-9770159-4-8}}</ref>

==History==

=== Dynamics ===
{{see also|Yellow River flood (disambiguation){{!}}Yellow River floods}}

The river has long been critical to the development of northern China, and is regarded by scholars as a [[cradle of civilization]].<ref>{{cite book |last=Little |first=Archibald John |title=The Far East |publisher=Clarendon Press |year=1905 |isbn=978-1-108-01387-1 |page=53}}</ref> Flooding of the river has also caused much destruction, including multiple floods that have resulted in the deaths of over one million people. Among the deadliest were the [[1344 Yellow River flood|1344 Yellow River Flood]], during the [[Yuan dynasty]], the [[1887 Yellow River flood|1887 flood]] during the [[Qing dynasty]] which killed anywhere from 900,000 to 2 million people, and a [[Republic of China era]] 1931 flood (part of [[1931 China floods|a massive number of floods that year]]) that killed 1–4 million people.<ref>{{cite book|title=The Great Big Book of Horrible Things|last=White|first=Matthew|author-link=Matthew White (atrocitologist)|publisher=[[W. W. Norton]]|year=2012|page=47|isbn=9780393081923|title-link=The Great Big Book of Horrible Things}}</ref>

The cause of the floods is the large amount of [[fine-grained]] [[loess]] carried by the river from the [[Loess Plateau]], which is continuously deposited along the bottom of its channel. The sedimentation causes natural dams to slowly accumulate. These subaqueous dams are unpredictable and generally undetectable. Eventually, the enormous amount of water needs to find a new way to the sea, forcing it to take the [[path of least resistance]]. When this happens, it bursts out across the flat [[North China Plain]], sometimes taking a new channel and inundating most farmland, cities or towns in its path.

The traditional Chinese response of building higher and higher [[levee]]s along the banks sometimes also contributed to the severity of the floods: When flood water did break through the levees, it could no longer drain back into the river bed as it would after a normal flood, as the river bed was sometimes now higher than the surrounding countryside. These changes could cause the river's mouth to shift as much as {{convert|480|km|-1|sp=us|abbr=on}}, sometimes reaching the ocean to the north of the [[Shandong Peninsula]] and sometimes to the south.<ref name="Gascoigne">Gascoigne, Bamber and Gascoigne, Christina (2003) ''The Dynasties of China'', Perseus Books Group, {{ISBN|0786712198}}</ref>

Another historical source of devastating floods is the collapse of upstream [[Ice jam|ice dam]]s in [[Inner Mongolia]] with an accompanying sudden release of vast quantities of impounded water. There have been 11 such major floods in the past century, each causing tremendous loss of life and property. Nowadays, explosives dropped from aircraft are used to break the ice dams before they become dangerous.<ref>[http://www.strategypage.com/htmw/htpeace/articles/20110329.aspx The Ice Bombers Move Against Mongolia]. strategypage.com (29 March 2011)</ref>

Before modern [[dam]]s appeared in China, the Yellow River used to be extremely prone to flooding. In the 2,540 years from 595 BC to 1946 AD, the Yellow River has been reckoned to have flooded 1,593 times, shifting its course 26 times noticeably and nine times severely.<ref name="Treg">Tregear, T. R. (1965) ''A Geography of China'', pp. 218–219.</ref> These floods include some of the deadliest natural disasters ever recorded. Before modern disaster management, when floods occurred, some of the population might initially die from drowning and many more would suffer later from the ensuing famine and spread of diseases.<ref>{{cite web|url=https://www.who.int/hac/techguidance/ems/flood_cds/en/index.html|archive-url=https://web.archive.org/web/20041231191845/http://www.who.int/hac/techguidance/ems/flood_cds/en/index.html|url-status=dead|archive-date=31 December 2004|title=Flooding and communicable diseases fact sheet|publisher=World Health Organization|page=2|access-date=27 July 2011}}</ref>

A similar proposal from the [[Southern Song|Song]] engineer Li Chun concerning flooding the lower reaches of the river to protect the central plains from the [[Liao dynasty|Khitai]] was overruled in 1020: the [[Chanyuan Treaty]] between the two states had explicitly forbidden the Song from establishing new moats or changing river courses.<ref name="Sedtime">Elvin, Mark & Liu Cuirong<!--sic--> (eds.)

The question of how aggressively flooding should be controlled, and whether it should be steered back to its original channels when it migrated, was a topic of controversy in the imperial court. Rival cliques made arguments based on budgetary, technical and strategic criteria. Geographer Charles Greer identifies two competing schools of thought on how to control the Yellow River. One, which he identifies as [[Confucianism|Confucian]], advocated containing the river between higher levees, thus maximizing the amount of river basin land that could be cultivated. The other, which he associates with [[Taoism]], favored lower levees separated by as much as 5–10 kilometers.<ref>{{cite book |author=Davis, Mike |title=Late Victorian Holocausts|publisher=Verso|pages=387–88|isbn=978-1-78168-061-2}}</ref> In one particular long-running debate during the 11th century reigns of the [[Emperor Renzong of Song|Renzong]] and [[Emperor Shenzong of Song|Shenzong]] emperors, when the river repeatedly broke its levees and migrated north and west, officials battled over whether expensive measures should be taken to return the river to its former channels.

The Yellow River passes through seven present-day [[Province (China)|provinces]] and two [[Autonomous regions of China|autonomous regions]], namely (from west to east) [[Qinghai]], [[Sichuan]], [[Gansu]], [[Ningxia]], [[Inner Mongolia]], [[Shaanxi]], [[Shanxi]], [[Henan]], and [[Shandong]]. Major cities along the present course of the Yellow River include (from west to east) [[Lanzhou]], [[Yinchuan]], [[Wuhai]], [[Baotou]], [[Luoyang]], [[Zhengzhou]], [[Kaifeng]], and [[Jinan]]. The current mouth of the Yellow River is located at [[Kenli County]], Shandong.

The river is commonly divided into three stages.

===Upper reaches===
{{unreferenced section|date=September 2015}}
[[File:Yellow river - A. Holdrinet.jpg|thumb|upright|Near [[Xunhua]], Qinghai]]
[[File:VM 6056 Liujiaxia Town.jpg|thumb|[[Liujiaxia]], Gansu]]

The upper reaches of the Yellow River constitute a segment starting from its source in the Bayan Har Mountains and ending at Hekou Town ([[Togtoh County]]), [[Inner Mongolia]] just before it turns sharply to the south. This segment has a total length of {{convert|3472|km|0|sp=us}} and total basin area of {{convert|386000|km2|sp=us|sigfig=3}}, 51.4% of the total basin area. Along this length, the elevation of the Yellow River drops {{convert|3496|m|0|sp=us}}, with an average [[Grade (slope)|grade]] of 0.10%.

The source section flows mainly through pastures, swamps, and knolls between the [[Bayan Har Mountains]], and the Anemaqen ([[Amne Machin]]) Mountains in Qinghai. The river water is clear and flows steadily. Crystal clear lakes are characteristic of this section. The two main lakes along this section are Lake Gyaring (Zhaling) and Lake Ngoring (Eling), with capacities of 4.7&nbsp;billion and 10.8&nbsp;billion m<sup>3</sup> (166 and 381 billion ft<sup>3</sup>), respectively. At elevations over {{convert|4290|m|sigfig=4|sp=us|abbr=on}} above sea level they are the two largest plateau freshwater lakes nationwide. A significant amount of land in the Yellow River's source area has been designated as the [[Sanjiangyuan National Nature Reserve|Sanjiangyuan ("'Three Rivers' Sources") National Nature Reserve]], to protect the source region of the Yellow River, the [[Yangtze]], and the [[Mekong]].

Flowing east at the eastern edge of the Amne Machin Mountains, the Yellow River enters [[Maqu County]] in [[Gansu]]. Here, the river skirts through the high-altitude peat bog known as the [[Zoigê Marsh|Zoigê Wetlands]] and makes a sharp turn towards the northwest forming the border between Maqu and [[Zoigê County]] in [[Sichuan]]. Flowing now along the northern edge of Amne Machin, the river reenters Qinghai and gradually curves north towards the Longyang Gorge at [[Xinghai County|Xinghai]].

The valley section stretches from Longyang Gorge in Qinghai to Qingtong Gorge in Gansu. Steep cliffs line both sides of the river. The water bed is narrow and the average drop is large, so the flow in this section is extremely turbulent and fast. There are 20 gorges in this section, the most famous of these being the [[Longyang]], Jishi, [[Liujiaxia Dam|Liujia]], Bapan, and [[Qingtong]] gorges. The flow conditions in this section makes it the best location for [[hydroelectricity|hydroelectric]] plants. The Yellow River exits Qinghai for the second and final time in these gorges and enters Gansu for the second time just before Liujia Gorge. Downstream from the Yanguo Gorge, the provincial capital of [[Lanzhou]] is built upon the Yellow River's banks. The Yellow River flows northeasterly out of Gansu and into [[Ningxia]] before the Qingtong Gorge.

After emerging from the Qingtong Gorge, the river comes into a section of vast [[alluvial plain]]s, the [[Yinchuan Plain]] and [[Hetao Plain]]. In this section, the regions along the river are mostly deserts and grasslands, with very few tributaries. The flow is slow. The Hetao Plain has a length of {{convert|900|km|-1|sp=us|abbr=on}} and width of {{convert|30|to|50|km|mi|0|sp=us|abbr=on}}. It is historically the most important irrigation plain along the Yellow River.

The [[Ordos Loop]] formed by an enormous twist of the Yellow River, beginning at [[Zhongning County]] in [[Ningxia]] and ending with a drastic eastward turn at its confluence with the [[Wei River|Wei]] at [[Tongguan County|Tongguan]] in [[Shaanxi]]. However, the official division for the middle reaches of the river run from [[Hekou, Togtoh County|Hekou]] in [[Togtoh County]], [[Inner Mongolia]], to [[Zhengzhou]], [[Henan]]. The middle reaches are {{convert|1206|km|0|sp=us|abbr=on}} long, with a basin area of {{convert|344000|km2|sp=us|sigfig=3}}, 45.7% of the total, with a total elevation drop of {{convert|890|m|sigfig=3|sp=us|abbr=on}}, an average drop of 0.074%. There are 30 large tributaries along the middle reaches, and the water flow is increased by 43.5% on this stage. The middle reaches contribute 92% of the river's silts.

The middle stream of the Yellow River passes through the [[Loess Plateau]], where substantial erosion takes place. The large amount of mud and sand discharged into the river makes the Yellow River the most [[sediment]]-laden river in the world. The highest recorded annual level of silts discharged into the Yellow River is 3.91&nbsp;billion tons in 1933. The highest silt concentration level was recorded in 1977 at 920&nbsp;kg/m<sup>3</sup> (57.4&nbsp;lb/ft<sup>3</sup>). These sediments later deposit in the slower lower reaches of the river, elevating the [[river bed]] and creating the famous "river above ground". From Hekou to Yumenkou, the river passes through the longest series of continuous valleys on its main course, collectively called the Jinshan Valley. The abundant hydrodynamic resources stored in this section make it the second most suitable area to build hydroelectric power plants. The famous [[Hukou Waterfall]] is in the lower part of this valley on the border of [[Shanxi]] and [[Shaanxi]].

===Lower reaches===
In the lower reaches, from [[Zhengzhou]] to its mouth, a distance of {{convert|786|km|sp=us|abbr=on}}, the river is confined to a [[levee]]-lined course as it flows to the northeast across the [[North China Plain]] before emptying into the [[Bohai Sea]]. The basin area in this stage is only {{convert|23000|km2|sp=us}}, a mere 3% of the total, because few tributaries add to the flow in this stage; nearly all rivers to the south drain into the [[Huai River]], whereas those to the north drain into the [[Hai River]]. The Huai River Basin, for example, is separated from the Yellow River Basin by the south dike of the Yellow River.<ref>{{cite book |last1=Yang |first1=Gonghuan |last2=Zhuang |first2=Dafang |title=Atlas of the Huai River Basin Water Environment: Digestive Cancer Mortality |date=2014 |publisher=Springer |isbn=9789401786195 |page=143}}</ref> The total drop in elevation of the lower reaches is {{convert|93.6|m|0|sp=us|abbr=on}}, with an average grade of 0.012%.

The silts received from the middle reaches form sediments here, elevating the river bed. Excessive sediment deposits have raised the riverbed several meters above the surrounding ground. That is why this part of the river is called [[The Earth Suspended River|the 'Earth Suspended River']]. At [[Kaifeng]], Henan, the Yellow River is {{convert|10|m|sp=us|0}} above the ground level.<ref>{{cite journal|url=http://emw21.com/CTS/GeorgeLeung/YRiver/geofo/geogren.html |author=Leung, George |title=Reclamation and Sediment Control in the Middle Yellow River Valley |journal=Water International |volume=21 |issue=1 |pages=12–19 |year=1996 |doi=10.1080/02508069608686482|bibcode=1996WatIn..21...12L |archive-url=https://web.archive.org/web/20131214151633/http://emw21.com/CTS/GeorgeLeung/YRiver/geofo/geogren.html |archive-date=14 December 2013 }}</ref>

[[File:Yellow River Delta.jpeg|thumb|right|300px|Yellow River Delta]]
The Yellow River is notable for the large amount of [[silt]] it carries—1.6 billion tons annually at the point where it descends from the [[Loess Plateau]]. If it is running to the sea with sufficient volume, 1.4 billion tons are carried to the sea per year.{{Citation needed|date=May 2009}} One estimate gives 34 kilograms of silt per cubic meter, as opposed to 10 for the [[Colorado River|Colorado]] and 1 for the [[Nile]].<ref name="Treg"/>

Its average discharge is said to be 2,110 cubic meters per second (32,000 for the Yangtze), with a maximum of 25,000 and minimum of 245. However, since 1972, it often runs dry before it reaches the sea. The low volume is due to increased agricultural irrigation, increased by a factor of five since 1950.

''The New York Times'' (2007-05-30)</ref> The Yellow River delta totals {{convert|8,000|km2|mi2|abbr=off|sp=us}}.

The highest volume occurs during the rainy season from July to October, when 60% of the annual volume of the river flows. Maximum demand for irrigation is needed between March and June. In order to capture excess water for use when needed and for flood control and electricity generation, several dams have been built, but their expected life is limited due to the high silt load. A proposed [[South–North Water Transfer Project]] involves several schemes to divert water from the [[Yangtze]]: one in the western headwaters of the rivers where they are closest to one another, another from the upper reaches of the [[Han River (Hanshui)|Han River]], and a third using the route of the old [[Grand Canal of China|Grand Canal]].{{Citation needed|date=May 2009}}

Due to its heavy load of silt the Yellow River is a [[Deposition (geology)|depositing]] stream{{spaced ndash}}that is, it deposits part of its carried burden of soil in its bed in stretches where it is flowing slowly. These deposits elevate the riverbed which flows between [[levee|natural levee]]s in its lower reaches. Should a flood occur, the river may break out of the levees into the surrounding lower flood plain and take
a new channel. Historically this has occurred about once every hundred years. In modern times, considerable effort has been made to strengthen levees and control floods.{{Citation needed|date=May 2009}}

[[File:Chinemys reevesii 02.jpg|thumb|The [[Chinese pond turtle]] (shown) and [[Chinese softshell turtle]] are both native to the Yellow River, but also [[Turtle farming|farmed]] in large numbers]]

The Yellow River is generally less suitable for [[Aquaculture in China|aquaculture]] than the rivers of central and southern China, such as the Yangtze or Pearl rivers, but aquaculture is also practiced in some areas along the Yellow River. An important aquaculture area is the riverside plain in [[Xingyang]], upstream from Zhengzhou. Since the development of fish ponds started in Xingyang's riverside [[Wangcun, Xingyang|Wangcun]] Town in 1986, the pond systems in Wangcun have grown to the total size of 15,000 ''[[mu (unit)|mu]]'' (10&nbsp;km<sup>2</sup>), making the town the largest aquaculture center in north China.<ref>{{cite web |url=http://www.zgnyqss.com/news/zonghe/2011/0930/95767.html |script-title=zh:黄河畔的荥阳市万亩鱼塘 |trans-title=Ten thousand of ''mu'' of fish ponds in the riverside Xingyang |website=zgnyqss.com |language=zh-hans |date=2011-09-30 |access-date=17 March 2013 |archive-date=1 February 2016 |archive-url=https://web.archive.org/web/20160201073225/http://www.zgnyqss.com/news/zonghe/2011/0930/95767.html |url-status=dead }}</ref>

The huge, entirely aquatic [[Chinese giant salamander]], a species that has declined drastically due primarily to persecution for food and traditional medicine, is native to the Yellow River and other Chinese rivers. It is farmed in large numbers in several parts of China and genetic studies have revealed that the captive stock mostly is of Yellow River origin.

[[File:Qikou.jpg|right|thumb|450px|Qikou town along Yellow River in [[Shanxi]] Province]]
A traditional belief was that the Yellow River flowed from [[Tian|Heaven]] as a continuation of the [[Milky Way]]. In a Chinese legend, [[Zhang Qian]] is said to have been commissioned to find the source of the Yellow River. After sailing up-river for many days, he saw a [[The Cowherd and the Weaver Girl|girl spinning and a cow herd]]. Upon asking the girl where he was, she presented him with her [[Shuttle (weaving)|shuttle]] with instructions to show it to the astrologer Yan Junping (嚴君平). When he returned, the astrologer recognized it as the shuttle of the Weaving Girl ([[Vega]]), and, moreover, said that at the time Zhang received the shuttle, he had seen a [[Classical planet|wandering star]] interpose itself between the Weaving Girl and the cow herd ([[Altair]]).<ref name="CBDChangChenchou">{{ChineseBioDict|Chang Chên-chou}}</ref>

The provinces of [[Hebei]] and [[Henan]] derive their names from the Yellow River. Their names mean, respectively, "North of the River" and "South of the River", although the border between them historically has never been stable, and currently the border between Hebei and Henan is not the Yellow River, but the [[Zhang River]] instead.

;Mother river, China's Sorrow, and cradle of Chinese civilization.
Traditionally, it is believed that the Chinese civilization originated in the Yellow River basin. The Chinese refer to the river as "the Mother River" and "the cradle of the Chinese civilization".
During the long [[history of China]], the Yellow River has been considered a blessing as well as a curse and has been nicknamed both "China's Pride" and "China's Sorrow".<ref>Cheng, Linsun and Brown, Kerry (2009) ''Berkshire encyclopedia of China'', Berkshire Publishing Group, p. 1125 {{ISBN|978-0-9770159-4-8}}</ref> In the twentieth-century, the river became a symbol of the rising Chinese nation in the face of Western and Japanese imperialism.<ref>{{Cite journal |last=Chen |first=Fei |date=2019 |title=Rediscovering the Yellow River and the Yangtze River: the Circulation of Discourses on the North–South Dichotomy between Late Qing China and Meiji Japan |url=https://www.cambridge.org/core/journals/international-journal-of-asian-studies/article/abs/rediscovering-the-yellow-river-and-the-yangtze-river-the-circulation-of-discourses-on-the-northsouth-dichotomy-between-late-qing-china-and-meiji-japan/FA789BD0E4991B50B13D68B3ECD3C6BF |journal=International Journal of Asian Studies |language=en |volume=16 |issue=1 |pages=33–51 |doi=10.1017/S1479591418000323 |issn=1479-5914}}</ref>

;River of disaster
Despite the Yellow River having a central role in the development of Chinese civilization on the North China Plain, flooding and constant rerouting of the river has also caused many great disaster to populations along the river, hence it is also known as a River of disaster ({{lang-zh|s=灾难河}}), with the disasters brought by the River said as history of disaster in the development of Chinese civilization, and the management of the Yellow River has been a great political trouble to various Chinese dynasties throughout history since ancient time.<ref>[http://36.112.18.13/Qikan/Article/Detail?id=75778371504849534853484949 基于黄河灾害研究综述的思考 On a Review of the Disasters from the Yellow River]</ref><ref>[https://cdo.develpress.com/?p=10096 黄河安澜呼唤生态保护和高质量发展]</ref>

;When the Yellow River flows clear
Sometimes the Yellow River is poetically called the "Muddy Flow" ({{lang-zh|first=t|labels=no|s={{linktext|浊|流}}|t={{linktext|濁|流}}|p=Zhuó Liú}}). The Chinese idiom "when the Yellow River flows clear" is used to refer to an event that will never happen and is similar to the English expression "when pigs fly".{{citation needed|date=March 2023}}

"The Yellow River running clear" was reported as a good omen during the reign of the [[Yongle Emperor]], along with the appearance of such auspicious legendary beasts as ''[[qilin]]'' (an African giraffe brought to China by a [[Bengal]] embassy aboard [[Zheng He]]'s ships in 1414) and ''[[zouyu]]'' (not positively identified) and other strange natural phenomena.<ref name=duy>{{Cite journal
