Rain and Floods

  • Raindrops are much smaller than we think! They are actually smaller than a centimeter. Raindrops range from 1/100 inch (.0254 centimeter) to 1/4 inch (.635 centimeter) in diameter.
  • Not including wind-driven rain, raindrops fall between 7 and 18 miles per hour (3 and 8 meters per second) in still air. The range in speed depends on the size of the raindrop. Air friction breaks up raindrops when they exceed 18 miles per hour.
  • A mere 2 feet of water can float a large vehicle or even a bus. Just 6 inches of rapidly moving flood water can knock a person down.
  • Natural flooding of river plains and deltas each year is essential for farming in many areas of the world as the waters bring nutrient rich silt deposits that create very fertile alluvial soils.
  • There are 25 river level gauge stations that have been installed to monitor water levels within rivers and streams potentially impacting Fort Bend County.
  • Many ancient communities relied heavily on the annual flooding of floodplain valleys on rivers such as The Tigris-Euphrates, the Nile, and the Ganges.
  • The Yellow River (Huang He) in China has had the four deadliest flood events in world history. The floods of 1931 resulted in 1 to 4 million people being killed.
