Floods In The United States (1900–1999)
Floods in the United States are generally caused by excessive rainfall, excessive snowmelt, and dam failure. Below is a list of flood events that were of significant impact to the country during the 20th century, from 1900 through 1999, inclusive. Decade of the 1900s Kansas River – May 1903 The greatest flood of the Kansas River on record of in the memory of the oldest inhabitants living along the stream occurred May 23 to June 13, 1903. Pacolet River (South Carolina) – June 1903 On June 6, 1903, after heavy rain, the Pacolet River destroyed or heavily damaged six large cotton mills, their associated dams, and 70 houses in the mill villages of Converse, Clifton, and Pacolet, South Carolina. Approximately 100 people were killed. Heppner flood – June 1903 The third deadliest flash flood in US history, the normally placid Willow Creek burst its banks during an intense rain and hail storm.

Rainfall
Rain is a form of precipitation where water droplets that have condensed from atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
