The Yellow River is the second longest river in China only inferior
to Yangtze River . It originates
from the northern slope of the majestic Bayankera Mountains in
Qinghai Province, traversing through nine provinces of Qinghai
Province, Sichuan Province, Gansu Province, Ningxia Hui Nationality
Autonomous Region, Inner Mongolia, Shaanxi Province, Shanxi Province,
Henan Province and Shandong Province before flowing into the Bohai
Sea. More than 30 branches and countless streams join the Yellow
River on the way to the sea. Being the river with the most excessive
silt in the world, the Yellow River gets its name from the muddiness
of its water, which bears a perennial ochre-yellow color.
Generally speaking, the Yellow River is divided into three stages.
In the upper reaches, the river starts from its original passes
in Qinghai Province, running 3,472 kilometers (about 2,157 miles)
through mountains and arid regions, swamps and grasslands just
before it makes a sharp turn to the south at Hekouzhen of Inner
Mongolia. In the middle reaches, it flows 1,206 kilometers (about
749 miles) to Taohuayu in Zhengzhou, Henan Province. At this stage,
this part of the mighty Yellow River runs through the vast region
of Loess Plateau, cutting the plateau into two parts like a sharp
sword: the left side of the river is Shanxi Province and the right
side is Shaanxi Province. The Yellow River has become the natural
geographical demarcation of the two provinces. And at the same
time, many of branches take a great amount of mud and sand into
it, so this area is the main silt source of Yellow River. A famous
engineering project is located in this section: the Xiaolangdi
Multipurpose Dam, which is used for flood control, ice jam control,
siltation control, irrigation, and water supply, as well as generating
hydroelectric power. In the lower reaches, it flows 786 kilometers
(about 488 miles) through the North China Plain, ending at the
delta of Bohai Sea. In this section, excessive sediment deposits
of the river have raised the riverbed several meters over the
surrounding grounds. Thus, the world famous 'River above Ground'
emerges.
