Question

why do you think flash floods occur​

Answer 1

Answer:

Flash floods may occur after the collapse of a natural ice or debris dam, or a human structure such as a man-made dam, as occurred before the Johnstown Flood of 1889. Flash floods are distinguished from regular floods by having a timescale of fewer than six hours between rainfall and the onset of flooding.[1] The water that is temporarily available is often used by plants with rapid germination and short growth cycles and by specially adapted animal life.
