1887 Yellow River flood
The 1887 Yellow River flood was a devastating flood on the Yellow River (Huang He) in China. This river is prone to flooding due to the elevated nature of the river, running between dykes above the broad plains surrounding it. The flood that began in September 1887 inundated the area, killing some 900,000 people. It was one of the deadliest natural disasters ever recorded.
For centuries, the farmers living near the Yellow River had built dikes to contain the waters, caused by silt accumulation on the riverbed. In 1887, this rising riverbed, coupled with days of heavy rain, overcame the dikes on around 28 September, causing a massive flood. Since there is no international unit with which to measure a flood's strength it is usually classified by the extent of the damage done, depth of water left and number of casualties.
The waters of the Yellow River are generally thought to have broken through the dikes in Huayankou, near the city of Zhengzhou in Henan province. Owing to the low-lying plains near the area, the flood spread very quickly throughout Northern China, covering an estimated 50,000 square miles (130,000 km2), swamping agricultural settlements and commercial centers. After the flood, two million were left homeless. The resulting pandemic and lack of basic essentials claimed as many lives as those lost directly by the flood itself. It was one of the worst floods in history, though the later 1931 Yellow River flood may have killed as many as four million.
