flash flood

Encyclopedia Article


A sudden flood that occurs when a large amount of rain falls in a short amount of time, often characterized by fast-moving water and destruction. Flash floods are common in Southwestern arroyos, canyons, and other permanent and ephemeral water systems, especially during the summer monsoons, and can be very dangerous.
