The Yellow River carries more sediment than any other in the world. [ 1 ] [ 2 ] During the 18 months after the river was closed, 1.8 billion metric tons of sediment had accumulated in the reservoir. Only 7% of the sediment-load was released downstream and the reservoir lost 17% of its capacity below a 335 m (1,099 ft) ASL elevation.
The Earth Suspended River (地上悬河 [1] is located in the lower reaches of the Yellow River, which is a world-famous geographical landscape. Also known as 'the raised bed river', its bed is more than 3 metres higher than the ground. In some places, the water level is even about 10 metres higher than the ground.
The river, flowing through the Loess Plateau, has been notorious since ancient times for its high sediment content and its propensity to flood and change course. Simple construction of riverbanks to prevent flooding would lead to sediment accumulation, creating an elevated river in downstream areas. [1]
The Yellow River Delta National Nature Reserve (YRDNNR) is a protected area in the city of Dongying, China, which covers wetland habitats on the shore of the Bohai Sea. These wetlands are formed through the deposition of silt by the Yellow River , forming a large and growing delta .
The amount of matter carried by a large river is enormous. It has been estimated that the Mississippi River annually carries 406 million tons of sediment to the sea, [5] the Yellow River 796 million tons, and the Po River in Italy 67 million tons. [6] The names of many rivers derive from the color that the transported matter gives the water.
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 billion tons in 1933. The highest silt concentration level was recorded in 1977 at 920 kg/m 3 (57.4 lb/ft 3).
Map of current configuration of Yellow River system, and the Luo (Lo) River. The Yellow River (Chinese: Huang He ) flows from the Tibetan Plateau to the Bay of Bohai over a course of 5,464 kilometers (3,395 mi), making it the second-longest river in Asia and the sixth-longest in the world .
The Loess Plateau is a plateau in north-central China formed of loess, a clastic silt-like sediment formed by the accumulation of wind-blown dust. It is located southeast of the Gobi Desert and is surrounded by the Yellow River. It includes parts of the Chinese provinces of Qinghai, Gansu, Shaanxi and Shanxi. [4]
