The Liao River (simplified Chinese : 辽 河 ; traditional Chinese : 遼 河 ; pinyin :Liáo Hé) is the principal river in southern Northeast China, and one of the seven main river systems in mainland China. Its name derived from the Liao region, a historical name for southern Manchuria, from which the Liaoning province, Liaodong Peninsula and Liao dynasty also all have derived their names. The river is also popularly known as the "mother river" in Northeast China. Coursing 1,345 kilometres (836 mi) long, the Liao River system drains a catchment basin of over 232,000 square kilometres (90,000 sq mi), but its mean discharge is quite small at only about 500 cubic metres per second (18,000 cu ft/s), about one-twentieth that of the Pearl River. The Liao River has an exceedingly high sediment load because many parts of it flow through powdery loess.
The Liao River is also an important geographical landmark, as it divides the modern Liaoning province into two broad regions — Liaodong ("east of Liao River") and Liaoxi ("west of Liao River").
The Liao River is formed from the confluence of its two main tributaries, the Xiliao River from the west, and Dongliao River from the east. The western tributary resides entirely in Inner Mongolia, and is formed by the confluence of the Xar Moron River and the Laoha River at approximately 43° 25' N, 120° 45' E, before being reinforced by another tributary called the Xinkai River at its lower section. The eastern tributary arises in western Jilin Province, and goes through an S-shaped course before meeting its counterpart near the junction region of Liaoning, Jilin and Inner Mongolia, approximately 42° 59' N, 123° 33' E.
The resultant river, the Liao River proper, then enters Liaoning Province and courses southwards through the Northeast China Plain, receiving numerous tributaries along the way. It makes a westward turn near Pingdingbao Town, Tieling County, and after receiving more tributaries, earns an infrequently used nickname Juliu River (巨流河, "giant stream river"). The Liao River will then course southwest until it reaches near the Liujianfang Hydrological Station (六间房水文站) at Tai'an County, and historically bifurcates into two distributaries, forming the Liao River Delta (辽河三角洲). The western distributary of the delta, originally smaller, was called the Shuangtaizi River (双台子河) until 2011, receives the tributary Raoyang River at Panjin's Panshan County before draining into the Liaodong Bay of the Bohai Sea west of Dawa County. The eastern distributary, originally the larger and the main body of lower Liao River, was called the Wailiao River (外辽河, "Outer Liao River"). The Wailiao River travelled southwards to pick up two large tributaries, the Hun River and Taizi River , at a confluence locally referred as the "Trident River" (三岔河), where it then adopted the new name Daliao River (大辽河, "Great Liao River") and drained into the Liaodong Bay just west of Yingkou.
However, the Liao River Delta has a flat topography made up of soft sediment soil, with meandrous waterways that had a rich history of rerouting. This coupled with the risk of storm surges due to the region's low elevation, created a huge problem in flood control. This flood risk at the coastal section of the Liao River system was particularly threatening to Yingkou, a city immediately adjacent to the mouth of Daliao River and home to 2 million people. In 1958, the upriver of the Wailiao River at Liujianfang was blocked off via a river engineering project, redirecting the water flow from the Liao River proper entirely towards the Shuangtaizi River (which was renamed to simply the "Liao River" in 2011), effectively separating the Hun River and Taizi River from the Liao River system. Therefore, the Daliao River system is considered an independent water system of their own since 1958, and the Hun and Taizi River are no longer tributaries of the Liao River. Also, due to the Wailiao River's upstream flow being cut off, the Liao River no longer has any distributaries, therefore the Liao River Delta technically also ceased to exist from 1958 onwards, however the term remains in use to describe the area of Panjin between the Liao River's left bank and Wailiao/Daliao River's right bank.
These following tributaries drain into the Liao River proper throughout its course within the Liaoning Province. [ citation needed ]
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. Irtysh is the chief tributary of the Ob river and is also the longest tributary river in the world. Madeira river is the largest tributary river by volume in the world.

The Liuyang River, also known as Liu River or Liuwei River, is a right-bank tributary of Xiang River, the largest tributary of Xiang River in Changsha, Hunan Province, China. The river has a length of 234.8 kilometres (145.9 mi) with its drainage area of 4,665 square kilometres (1,801 sq mi), accounting for 39.47% of the total area of Changsha, with surface water resources of 4,506 million cubic meters, accounting for 41.08% of that. It flows through Liuyang City, Changsha County, Yuhua, Furong and Kaifu Districts, and merges into Xiang River at Xinhe Delta Mouth of Kaifu District.
The Taizi River is a major river in the Liaoning province of Northeastern China. The river was historically also known as Yan River (衍水) or Liang River (梁水). It was originally the third largest tributary of the Liao River, southern Northeast's principal river, draining with the neighboring Hun River into a confluence known as "Trident River" near Haicheng, until a river engineering project in 1958 cut off the eastern distributary of the river delta from the Liao River's main course, making the Hun River and Taizi Rivers a separate system that drains into the Bohai Bay independently from the Liao River. However, both sister rivers are still usually considered a part of the Liao River system because they are both within the historical Liao River drainage basin.
