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.
There are two common types of pluvial flooding: 1  Intense rain saturates an urban drainage system. The system becomes overwhelmed and water flows out into streets and nearby structures. 2  Run-off or flowing water from rain falling on hillsides that are unable to absorb the water.
