Yellow River
China's muddy mother river, cradle of Chinese civilization
The Yellow River takes its name from the immense load of loess silt it carries, which stains the water ochre and, over millennia, has built the fertile plain where Chinese civilization began. Second only to the Yangtze in length within China, it loops north and then south across the country in a giant bend before reaching the sea. Generous and treacherous in equal measure, it has nourished and drowned the people of its banks so often that it earned the bleak nickname China's Sorrow.
Rising in the Bayan Har Mountains on the Tibetan Plateau, the river runs about 5,464 kilometers to the Bohai Sea. Its defining feature is the loess plateau it crosses, where soft windblown soil washes into the channel in staggering quantities — the river carries more sediment than any comparable waterway. That silt settles on the bed downstream, raising the river above the surrounding plain so that it flows between dikes higher than the rooftops beside it. When the dikes fail, the river can leap its banks and even shift its mouth by hundreds of kilometers.
Along the middle and lower reaches lie the heartlands of early dynastic China, and controlling the river's floods was a test of every government that ruled them. Its catastrophic inundations are among the deadliest disasters in recorded history. Today dams, reservoirs and silt-flushing schemes manage the flow, but the river now runs so heavily tapped for farming and cities that in dry years it has failed to reach the sea at all. It remains the symbolic mother river of the Chinese nation.
