Difference Between Flood and Flash Flood

Flood vs Flash Flood

Flood and flash flood are natural disasters created by the changes in the weather that are causing calamities in the world. Be it because of recurring storms, hurricanes, tropical cyclones and heavy rains from monsoons and some tropical depression, flood is always expected as the incoming result. Flood is the general term for the catastrophe that is basically defined as an overflow of water from lakes and rivers that eventually covers a large width of land that is not covered with water in a normal time being.


Floods can damage houses and establishments that are near to flooded areas. This catastrophe can take away lives, too. These possibilities can be easily eliminated if one pursues to live or build something far from places with large water banks like rivers. However, majority of people believe that living somewhere near to places with waters could be a gain of a cheap living expenditure. This is the reason why many people, especially those with families, still chose to inhabit places that are threatened of flood damage. The cost of flood damage and the rate of death exceeds every time a periodic flooding repeats.

Flash Floods

Flash flood is one extreme type of flood that is categorized within the fast kinds of reverine flood. The ‘flash’ attached to the term refers to its rapid effect. This type of flood is found to be the result of convective moisture from air or from waters, like rain and snow, that are falling from the sky. Some other types of flood include:

Slow kinds of riverine flood – Sufficiently defined as the overflowing of water from its boundaries that is caused by heavy rains and unexpected melting of ice especially those that are coming from elevated areas like mountains.

Estuarine and Coastal flood – These are almost similar with each other since their causes are from sea hazardous storms. An offshore elevation of water, commonly called as storm surge, falls in this category regardless of the cause.

Catastrophic flood – This is a kind of flood that results from a series of particular misfortunes. For an instance, during earthquake or a volcanic eruption, undesirable events like dam breakage may happen, which will eventually result to catastrophic flood.

Muddy flood – This type of flood is cause by a runoff that is accumulated on cropland. Muddy floods of massive movements are one the most dangerous catastrophes since it carries sediments of suspended objects from land.

There are numerous ground-breaking effects that come with floods. Bad effects are truly heart-breaking but there are some good effects, as well. It can kill lives; it will destroy our means of living and can be the cause of certain waterborne diseases. Positive effects are from smaller, frequently occurring floods, like fertilizing the soil, recharging grounds with insufficient rate of moisture and fishes can travel across new habitats, too.

In brief:

1. Flash flood is another type of flood that is rapid in the manner of elevating water to lands.

2. Flood is a general term; flash flood is one of its types and is very specific when it comes to causes.
