What is a Flood: Definition and Explanation

Floods are probably amongst the most vicious, and disgusting, natural disasters that most of us, and most animals, experience every couple of years. Be it a river overflowing, or metamorphosing rain and snow, a gradual rise in temperature— floods affect billions across the globe and bring with them loss of property and life. People however are left wondering how these floods occur or more precisely, what is defined as a flood. In this blog, we explain it in a way that is easy and simple for anyone to understand.

How do we define a Flood?

Flooding happens when water spreads over dry land. Despite the several ways this could happen, the end result is always an inflow of water that submerges lands, which results in altering the geography of that specific area along with the destruction and damage to several buildings, roads, and even areas. Floods could arise as a result of numerous heavy rainstorms or on the other hand, they could be the result of extreme hurricanes, but they could also be as a result of poor construction and human activity focused on globalisation.

How Flooding Takes Place

To put it more simply, flooding occurs when the amount of water exceeds what a surface can accommodate or remove. There could be several explanations for this flooding, to begin with:

1. Pour-down Precipitation

Sometimes too much water falls on the ground in a very short span of time, and as a result, the surface runoff water is unable to absorb all the water. Due to heavy precipitation, rivers and lakes overflow from their banks, and the water overpowers adjacent land. High storms and continuous series of storms are responsible for the floods in certain areas.

2. Stream Inundation

An inundation can occur in places that have frozen water due to heavy winds precipitating small moving water droplets to precipitation in the form of ice particles. A river backflows when its mouth is close to the ocean and this deficiency of water in the ocean creates pressure. With that said, any and all dry lands near that river could be put at potential risk.

3. Tide Flooding

Sea level rise and severe storms can lead to low-lying coastal areas being greatly affected. Storms and high tide events can cause seawater surge and these drown the adjacent lands. Water can creep into coastal regions as a result of a hurricane or a typhoon along with storm force winds.

4. Flood due to melting of glaciers

Another potential cause of backflow floods are the glaciers covering the east Asian region. The floods, if they do appear seem to cause great damage when they sweep through China, Japan and Korea; torrents of rain and floods are able to flow through quickly due to wind patterns. Rapid melting of frozen water droplets in the spring season can set off guidelines where frozen water can feed into large rivers.

5. The Outburst Flood

Dams and levees are manmade structures designed to contain water in lakes or rivers. In case these structures break, flooding may occur. Such incidents put the residents near the dams or levees at risk.

6. Urbanization

Floods are more prevalent in the developing areas now, as there is plenty of pavement and masses that cannot allow for water penetration. If it rains, it has to go somewhere, and that somewhere would be the pavement, causing flooding. Poor drainage and thickly populated areas help worsen the floods.

The Impact of Floods

Flooding may bring destruction to homes, industries as well as infrastructural development done in an area. They have the power to wipe out road systems, farms, bridges as well as townspeople. People are displaced and some may die while others lose their property.

Moreover, floods will also render islands dirty or dysfunctional and people will suffer trying to find drinkable water.

More than people’s lives and their property, floods can also destroy the economy of a country – state, region or area! Food production will be affected and there will be food scarcity. Depending on the situation, affected areas may take several months or years to recover which will be an expensive affair.

What to Do in Case of a Flood to Keep Yourself Out of Risk

Floods can be unpredictable, but there are steps we can take to stay safe:

1. Stay Informed: If weather reports warn of a flood or change in weather conditions, everyone should heed the warnings because authorities will normally advise on when and where the floods are likely to happen. Nowadays, floods are becoming more severe and widespread.

2. Have an Emergency Kit: It may be wise to have food, water, medicines and essential documents easily reachable in a place and all your emergency supplies in the needed kits ready and easily accessible in case you need to leave in a hurry. Start praying for effective International and National movements to recover these resources for food security.

3. Evacuate When Told:People from a particular area need to get out when Local authorities order an evacuation while going outside. It is important to not wait until there are last few options available after the last minute because flooding can occur and thus there can be traffic more than roads can handle.

4. Don’t Drive Through Flooded Areas:This requires ambition and even self-control of being tempted to drive through the flooded area where traffic control even after rough seas is spelt by just a few inches of water. If possible avoid traveling through flooded roads, fences should covered.

5. Find Higher Ground:If caught in a flood the best tactic would be to relocate into an area without water and topographic elevation would be a breadcrumb. Basements and regions close to water sources should be shunned because flooding has the potential to engulf everything in its path.

Preventing and Reducing Flood Risks

Therefore it would not be wrong to say we have found our flood squad, with minimal to no changes in structures flood consequences and survival strategies need to change. Schools should work on how to develop better drainage during monsoon schools along with governments should think of building flood barriers during the monsoon as well as replanting trees to prevent soil erosion during heavy rains. Building homes and businesses in flood-prone areas should be carefully planned, and people should be educated about how to prepare for floods.

Final Thoughts

Floods can be a horrible, and forceful assault of nature, but with knowledge of its reasons and how to avoid being its victim, it becomes easy to cope with. Providing aid in maintaining them, developing paying attention to communication outlets, and being educated is how we enhance safety in our societies. Weather is not something that we can influence, but human actions can still provide some safety to people, and even pets when calamity hits.Be prepared, and do not forget to take care of yourself!
