flash flood is due to a sudden surge of water level in a river or a dry canal basin. imagine this:
rain on mountains and all water collects in channels that slope down the mountians and by the time the water reaches a certain spot, a lot of water has been accumulated and this is called a flash flood, as suddenly water rises

Flash flooding can occur anywhere and is associated with very heavy rain in slow moving severe thunderstorms. Strong updrafts hold huge amounts of water aloft before releasing it in an intense deluge. The area on which the rain falls is relatively small but a lot of rain falls there. The water runs off the ground filling drains and creeks rapidly. Rainfall rates of 100mm or more in an a hour are common in flash flood events.
