Floods have been among the deadliest natural disasters, causing widespread devastation and loss of life. Over the past 300 years, several catastrophic floods have occurred, with the 1887 Yellow River Flood in China resulting in approximately 900,000 casualties due to heavy rainfall and dike failure. The 1931 China Floods, also known as the deadliest flood in recorded history, caused around 1,000,000 deaths due to heavy rainfall and snowmelt.

Other notable floods include the 1935 Yangtze River Flood and the 1954 Yangtze River Flood, both in China, with casualties of 145,000 and 30,000, respectively. The Banqiao Dam Failure in 1975, caused by Typhoon Nina, led to 171,000 deaths. More recent floods, such as the 2010 Pakistan Floods and the 2013 North India Floods, have also caused significant casualties, highlighting the ongoing threat of flooding in vulnerable regions. Please note that some numbers of casualties are approximate values.

For more detailed information on these and other floods, various online resources such as the National Oceanic and Atmospheric Administration (NOAA), the International Disaster Database (EM-DAT), and the World Meteorological Organization (WMO) provide comprehensive data and analyses. These sources offer valuable insights into the history, causes, and impacts of floods, helping us understand and prepare for these formidable natural events.
