On August 18, 1931, the major rivers of eastern China flooded disastrously into nearby towns and farms. The Huai, Huang (Yellow), and Yangtze rivers all overflowed their banks. While many died from drowning or being crushed by debris others starved or were or felled from the effects of waterborne diseases such as cholera and typhus. Millions were left injured or homeless.
The floods were the result of unusual weather patterns and decades of poor river management. A long period of drought was followed by a severe winter, including record snowfall and heavy rains. This raised the water level of the rivers, whose beds had already become higher than the surrounding land. Silt had built up on the riverbeds as engineers constructed earthen levees and dikes along river banks, blocking the river’s natural flood plain. In 1931, pressure from the unusually heavy river burst the levees.
