    • Between 1998-2017, 2 Billion people have been affected worldwide due to floods. 
  • Causes: 
    • These are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
  • Types of Floods: 
    • Flash Floods: These are caused by rapid and excessive rainfall that raises water heights quickly, and rivers, streams, channels or roads may be overtaken.
