Flash flood is an extreme type of flood that is categorized within the fast kinds of riverine floods. The âflashâ attached to the term refers to its rapid effect. This type of flood is found to be the result of the convective moisture from the air or waters, like rain and snow that fall from the sky.
Causes of flooding. A flood occurs when a river bursts its banks and the water spills onto the floodplain. Flooding tends to be caused by heavy rain: the faster the rainwater reaches the river channel [river channel: The part of the river that holds the water. ], the more likely it is to flood.
