What is a Flood?
A flood is when a place gets more water than it's supposed to in an area. Mainly caused by rain, if it's a natural flood, and if it's an unnatural flood it is mainly caused by broken pipes.
What is a Natural Flood?
A natural flood is a flood caused by the effect of nature. Some examples of a flood is when snow melts in the spring and there are lots of big puddles on the streets and in yards. This is not a big flood but it still has a larger amount of water that is supposed to be in the area making it a flood. Another way a natural flood can form is by a large amount of rainfall that goes into a river and overflows into land that does not usually get that much water as a river gets. This is also flooding the river too, because when a river overflows it is getting more water than it normally does.
What is an Unnatural Flood?
An unnatural flood is a flood that is not made by nature or weather. Unnatural floods can happen when a pipe breaks in a house while there is water in it and water fills the house.
How do I Prevent a Flood?
There are a couple ways to prevent floods but, unfortunately only natural floods and no ways of preventing unnatural floods but engineers are finding ways to prevent unnatural floods just like they already have done in the past with natural floods. One of the ways that you can prevent natural flooding is by levees. Levees is a wall of natural substances alongside a river made to prevent overflowing that helps stopping the floods. However if there gets to be too big of an overflow or too strong a current levees can potentially break, as in the case of the tradgic new Orleans flood.
How to Prepare for a Flood?
You can prepare for a flood in many ways but one way the government and or community prepares for a flood is very different than an average person might prepare for one. The government has the rights to build on public property. This can help because they are able to build dams which helps the water flow and keeps the water from getting too high. One way to prepare for a flood if you live near the equator and get a lot of rain is elevating your house by putting support beams underneath. This helps because it still keep the house steady and gives your house some elevation which can potentially save and protect your house if you get a flood around one to two feet high.
An average person can't fully prepare for a natural flood, but there are a few things they can do. Don't buy or build a house in a low lying area or flood plane. Go to the highest level of your dwelling if there is a flood. It is always good to have fresh drinking water available with you and a small food suply.
Historical Flood Examples
One of two historical examples is the 1887 Yellow River flood in china. This was the largest and strongest flood on record. The Yellow River flood killed between 900,000 to 2,000,000 people. after the flood came it left two million people homeless. The Yellow River flood was so big that it covered 50,000 square miles of land.
The second historical event is the flood in Nigeria that occurred on October 10, 2012. It was one of the worst floods with over 1.3 million Nigerians displaced and 431 deaths. Heavy rain submerged much of Belta, Bayelson, and many other states in the southwest region. 350 communities were effected and 120,000 people were left homeless. Thousands of homes, 20 health clinics, 5 hospitals, as well as a dozen schools, churches and government buildings were destroyed. Crops were also lost damaging peoples livelihood. 17.6 billion naira (US $111 million) money was allocated to agencies who responded to flood damage.
