Answer:
Explanation:
Flooding usually happens when large volumes of rainfall occur in relatively short time periods. Dependent on soil variants, water content, nearby trees growth and density, these are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland. Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. Flash floods, in particular, are characterised by their relatively short duration; they typically happen within minutes or hours of due to extra rainfall, broken dams or levees during slow-moving thunderstorms or hurricanes -storms generally include heavy rainfall, lightning and strong winds. Thesephenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.
The characteristics of a flash flood are:
A flash flood may be defined as a sudden increase in water caused by heavy rain and thunderstorm.
A flood arises when an enormous amount of water is gathered due to rainfall or thunderstorm in a very short time. These conditions are occurs in tropical rain forests where the average rainfall is high. Flooding also relates to the quality of soil present, as the soil has the power of holding water capacity. But in heavy floods, the quality of soil is not performed any role.
Therefore, the characteristics of flash floods are briefly described.
