The Geography of the Yellow River
The Yellow River is the sixth longest river in the world, but over 100th for discharge! This is because it flows through dry areas of North China, which draw on it for agriculture, industrial, and municipal water needs.
Known as "the Mother River of China", it still contributes greatly to the water needs of some of the major historical cities of China.
Once known as "China's Sorrow" its flooding has largely been alleviated by dams and dykes (and the heavy abstraction mentioned above).
The Course of the Yellow River
The Yellow River originates from the Roof of the World (the Qinghai-Tibet Plateau) in the Kunlun Mountains in western China.
It flows through nine provinces in the dry north of China: Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan, and Shandong, before flowing into the Bohai Gulf at the city of Dongying.
The Yellow River is 5,464 kilometers (3,395 miles) long, the second longest river in China after the Yangtze River.
The Ordos Loop is the characteristic rectangular "n" shape that the Yellow River takes round the city of Ordos in Inner Mongolia, as it deviates 600 km north, 300 km east, then 600 km south.
Tributaries of the Yellow River are many, but none particularly famous, including the White, Black , Qingshui, Fen, Wei, Luo, Qin, and Dawen rivers.
Location and Drainage Area
The Yellow River Basin is located between Qinghai and Shandong provinces, with a characteristic broad serpentine shape, taking it as far north as Inner Mongolia and as far south as Sichuan.
It has an east-west extent of 1,900 km (1,180 miles; 96–119° east) and a north-south extent of 1,100 km (684 miles; 32–42° north), with a total basin area of 752,000 km2 (290,000 mi2), larger than Texas or France.
The Upper Reaches of the Yellow River
The upper reaches of the Yellow River have a total length of 3,472 kilometers (2,157 miles) and total drainage area of 428,000 km2 (165,000 mi2), bigger than California.
The source section flows mainly through remote pastures, swamps, lakes, and gorges between the source and its emergence into more populated areas at 1,600 meters (5,200 ft) above sea level around Lanzhou in Gansu Province.
There are three large reservoirs in the upper reaches with hydroelectric dams: Liujia Gorge, Lijia Gorge, and Longyan Gorge.
Higher up the two largest lakes are Ngoring Lake (Elinghu) and Gyaring Lake (Zhalinghu), where fish are plentiful and protected in the Three River Sources Nature Reserve. (The Yangtze and Mekong also have their sources in that area.)
The Middle Reaches of the Yellow River
The middle reaches is officially from Hekou in Inner Mongolia, at 1,200 meters (3,900 ft) above sea level, to Zhengzhou, Henan Province, 100 meters (300 ft) above sea level. The middle reaches measure 1,206 kilometers in length, draining 344,000 km2 (133,000 mi2), the size of Germany.
Most branches flows through China's Loess Plateau region, causing serious erosion and sedimentation of the Yellow River.
The Xiaolangdi Multi-Purpose Dam protects Luoyang (20 km SE) from flooding, provides municipal water supply, irrigation, and a significant amount hydroelectric power (1/4 of the Grand Coolie Dam, North America's largest). It is the critical flood control project for the lower reaches of the Yellow River.
The "Yellowest" Waterfall in the World
Hukou Waterfall is the second largest waterfall in China and the most sedimented major waterfall in the world. Its width changes with season, from 30 meters (98 feet) to 50 meters (164 feet). It's 18 meters (60 ft) high, forming a magnificent scene, like a giant chocolate fountain. Learn more about Hukou Waterfall.
The Lower Reaches of the Yellow River
The Lower Reaches, from Zhengzhou to the Pacific (the Bo Sea Gulf), have a length of 786 km, and drain a mere 23,000 km2 (8,880 mi2), the size of New Jersey. Excessive sediment deposits have raised the riverbed several meters above the surrounding ground, forming the worldly famous "above ground river"!.
