What is Flood?

A flood is capable of damaging houses and establishments that are near to flood-prone areas, while also threatening the lives of those who live close by. Floods can happen due to changes in seasons such as changes in precipitation and snowmelt. These possibilities can be easily eliminated if one pursues to build their dwellings far from places with large bodies of water such as rivers and lakes. However, majority of people prefer living close by to bodies of water because of aesthetic as well as financial reasons since this kind of land tends to be estimated at very low values. Apart from that, people have traditionally lived and cultivated by rivers since the land is flat and fertile.

What is Flash Flood?

Flash flood is an extreme type of flood that is categorized within the fast kinds of riverine floods. The ‘flash’ 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. 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 to 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 instance, during an earthquake or a volcanic eruption, undesirable events such as dam breakage may happen, which will eventually result in a catastrophic flood.

Muddy flood – This type of flood is caused 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.
