Main Rivers


 

China abounds in rivers, lakes and water resources.

Due to its topographical features, most rivers flow east or south into the ocean, thus forming vast outflow river valleys that constitute nearly two-thirds of the national total area. Most of them belong to the Pacific Valley and a small number fall into the Indian Ocean Valley. Only the Erix River in the Xinjiang Uygur Autonomous Region that flows westerly out of China belongs to the Arctic Ocean Valley.

More than 1,500 rivers have a drainage area of over 1,000 square km. The total volume of runoff stands at 2.7 trillion cubic meters, ranking sixth in the world. Holding the top five positions are Brazil, Russia, Canada, the United States and Indonesia. Famous rivers in China include the Yangtze River, the Yellow River, the Heilongjiang River, the Yarlung Zangbo River, the Pearl River and the Huaihe River. The Tarim River in Xinjiang is the longest inland river in China. Running across deserts, it has been known as the "river of life.¡±
Because most of the main rivers originate from the Qinghai-Tibet Plateau with big falls, China has abundant waterpower resources, with total reserves of 680 million kw, ranking first in the world. However, the waterpower resources are unevenly distributed, with 70 percent in southwest China. The Yangtze River system has the most waterpower resources, which account for nearly 40 percent of the national total, followed by the Yarlung Zangbo River system. The Yellow and Pearl river systems also abound in waterpower resources.

 

Yangtze River


 


Yangtze River The largest in China and the third longest in the world, the Yangtze River rises in Geladaindong, the highest peak of the Tanggulashan Mountains. It flows 6,300 km eastward traversing 11 provinces, autonomous regions and municipalities before emptying into the East China Sea. It has numerous tributaries, including the Yalong, Minjiang, Jialing, Hanjiang, Wujiang, Xiangjiang and Ganjiang rivers, with a combined drainage area of over 1.8 million square km, accounting for 18.8 percent of China's total area. Its annual average runoff stands at 951.3 billion cubic meters, accounting for 52 percent of the national total. It is a major artery of inland water transportation in China.

Flowing easterly from Fengjie County, Chongqing Municipality, to Yichang City, Hubei Province, the Yangtze River cuts across Wushan Mountain, forming three gorges with a total length of 193 km. The famous Three Gorges Water Project began construction at the eastern section of the area in 1994. After completion in 2009, the project is expected to be able to control catastrophic flooding in nearby drainage areas that occurs once in a century. It is also expected to annually generate 84.7 billion kwh of electricity, improve navigation conditions, and ensure water supply in urban areas and irrigation of farmland in the middle and lower reaches of the Yangtze River.

 

Yellow River


 


Yellow River The second largest in China, the Yellow River originates from the northern foot of Bayan Har Mountain in Qinghai Province. It flows 5,464 km easterly across nine provinces and autonomous regions before emptying into the Bohai Sea. With a drainage area of more than 750,000 square km, its annual average runoff is 66.1 billion cubic meters. It has more than 40 tributaries, of which Fenhe and Weihe rivers are the main ones.

The middle section of the river traverses the Loess Plateau with loose soils, making it a river with highest silt content in the world. Around a quarter of total silt it carries is deposited at downstream riverbeds, making them rise 10 cm a year on average. Thus, the riverbed of many downstream sections of the river is 3 to 5 meters higher than the surrounding land.

The upstream of the Yellow River runs through the junction of the country's first- and second-terrace regions, a section reserving most waterpower resources of the river. Many water conservancy projects have been built in this area, including those at Longyangxia, Liujiaxia and Qingtongxia. The middle reaches of the river also abound in waterpower resources. The Xiaolangdi Water Project, situated in Henan Province, is under construction.

 

Heilongjiang River

 


Heilongjiang River Situated in the northernmost part of China, the Heilongjiang River is the boundary river between China and Russia. Its mainstream flows 3,420 km within the boundaries of China, with a drainage area of around 900,000 square km.

 

Songhuajiang River

 


Songhuajiang River The Songhuajiang River flows 2,308 km, with a drainage area of 557,180 square km and an annual runoff of 76.2 billion cubic meters.

 

Liaohe River

 


Liaohe River The Liaohe River flows 1,390 km, with a drainage area of 228,960 square km and an annual runoff of 14.8 billion cubic meters.

 

Pearl River

 


Pearl River The largest in south China, the Pearl River flows 2,214 km, with a drainage area of 453,690 square km and an annual runoff of 333.8 billion cubic meters. In terms of runoff volume, it is considered the second largest in China, next to the Yangtze River.

 

Huaihe River

 


Huaihe River The Huaihe River flows 1,000 km, with a drainage area of 269,283 square km and an annual runoff of 62.2 billion cubic meters.

 

Beijing-Hangzhou Grand Canal

 


Beijing-Hangzhou Grand Canal Starting from Beijing's Tongzhou District in the north, the Beijing-Hangzhou Grand Canal extends 1,800 km to Hangzhou, Zhejiang Province in the south. Flowing through Beijing, Tianjin, Hebei, Shandong, Jiangsu and Zhejiang, it connects the Haihe, Yellow, Huaihe, Yangtze and Qiantangjiang rivers. First dug in the fifth century B.C., the canal served as an important channel for the transport of grain in ancient China. The earliest and longest artificial waterway in the world, its southern section is still navigable.
