Floods are one of the deadliest calamities that can strike humans. They bring immense destruction and, worst of all, claim lives. We’re looking at when are floods most common and where do they occur.
Nowadays, it is not even easy to tell when a flood can occur due to global warming.
Naturally, waves are likely to occur due to heavy and frequent rains.
This leads to the overflow of water into the dry land.
According to the Red Cross, 90% of natural disasters are related to floods, and they cause at least 100 deaths every year in the US. Here are areas where floods are frequent.
Areas Close To the River
Cities close to a river are prone to floods.
When a river overflows and breaks its banks, the waters rush into the neighboring dry land.
Waves are likely to happen during the rainy season and when there are ice jams or melting snow.
According to one scientific study, about 41 million people in the US are at risk of river flooding and especially those living in the lowlands.
Americans love the coastal areas because of the beautiful sceneries. Flooding puts around 8.6 Americans at risk of coastal flooding as they build homes along the coast. Nothing beats a house with a beach view.
The flooding is believed to be the worst as the water comes with massive force powered by winds like a hurricane.
They have killed many people in the history of America.
The water is driven by strong winds, creating a massive wall of water.
These waters bring down even the most substantial houses and sweep away vehicles.
This storm surge causes incredible devastation.
The low-lying areas are the frequent victims of flash floods.
This type of flooding occurs suddenly after several hours of continuous heavy rains.
Lack of proper drainages causes water accumulation and leads to flooding as the water cannot find appropriate ways to flow away.
Levee or dam breaks and water overflow caused by ice jams or debris also lead to flash floods. Since they are unpredictable, they can result in massive fatalities.
Coastal floods, river floods, and flash floods can happen in urban areas. However, urban floods are caused by heavy rainfall and not due to the overflowing of a water body. A city’s drainage system is overwhelmed by large amounts of water. The water floods into basements parking lots, roads, and other areas where water is supposed to enter.
Floods in Different Seasons
Flooding can occur any season, though they are prevalent in particular areas. There is no safe season except the winter one. Here are the reasons why those living the areas should watch out for floods, regardless of the season.
Areas that received heavy snowing during winter start melting around this time.
People living below the snow-laden mountains can easily experience flash floods.
The warmer temperatures cause the snow to melt, and the water becomes too much for ditches and streams to handle.
Spring and Summer
During the summer and spring seasons, thunderstorms are experienced and can lead to heavy rainfall.
In the US, monsoon storms are known to cause flooding despite the warm temperature experienced during summer. They can quickly create rapid or flash flooding.
Summer and Fall
Coastal floods occur during these seasons.
They are common in Florida, Louisiana, Texas, and Georgia.
They form severe hurricanes and create big disasters.
These are the worst floods and the most horrible battles that America has to fight in the summer and fall seasons.
What are the Impacts of a Flood?
A flood causes damage worth billions of dollars globally every year.
In the US alone, $8 billion worth of property is believed damaged by floods.
While it’s estimated that about 100 people are killed by floods every year, in China, the Yellow River Valley killed millions.
Heavy rain causes a lot of problems, including lack of clean water, power and can cause waterborne diseases such as cholera, hepatitis A and typhoid.
Prevention of Floods
Flooding is not preventable in low land areas, especially during heavy rainfall seasons.
Floodplains, including the Mississippi Valley, Tigris-Euphrates, and the Nile River agriculture flourish due to the silt deposits full of nutrients left by floods.
However, the risk of damage and death increases because of human activities such as the construction of roads, homes, and commercial buildings.
To prevent floods, engineers have created massive dikes and levee systems. For example, the Netherlands dams and dikes and New Orleans levee system.
How to stay safe from floods
Floods can be in the form of slow-moving or raging waters.
Most people underestimate the power of water, leading to injuries, and loss of lives.
Any water that is six inches can cause imbalance and make someone fall. The first thing to do is to move to higher grounds. Stay safe from floods by:
- Avoid building your home in flood plains.
- Keep your furnace and home heater elevated to avoid considerable damages in case of a flood.
- Pay attention to flood warnings.
- If you have enough time to evacuate your family, switch off utilities.
- Avoid getting into contact with the floodwater. It is dirty and likely to contain sewage, gasoline, and oil.
The nature of water is that it moves from high grounds to lower areas.
Rain means when floods occur, the low area experience more destruction.
Any region that receives high levels of rainfall, too much water accumulates, and it cannot be drained or absorbed fast enough, leads to a flood.
In various cities around the world, buildings and other constructions have sprung up where they are not allowed. They block waterways, which makes such areas prone to floods.
