Transcript of Floods
Unfortunately, this catastrophe has also been proved as a man-made disaster.
Floods are massive threats to the abundance of humans and animals as they can inflict damage on food, crucial institutions, homes, and important stock. Many people die from drowning in waters and from catching mosquito spread diseases because of their contact with floods. One that is common in other foreign countries is Malaria. What is flood? Helloooo der. Speaking of floods... "Flash Floods" can be rapid and accumulate within minutes or a few hours after heavy rainfall, tropical storm or hurricane, failure of dams, levees or releases of ice jams.
Levee: A raised riverside built up naturally by the river by deposition of silt during flooding. (dictionary meaning)
Actually, flash floods pose the greatest risk to society, even if they last for a short period of time. That is because they are rapid and are increasingly unexpected. After all they are floods.
"Slow Onset Floods" are generally way longer than flash flooding. They can take place for a at least 1 week or so. They can even prolong their time period by 1 week. Slow onset floods can even last for a month. Therefore, they can lead to serious situations such as loss of stock
(oO o )~
"Rapid Onset floods" are known to last a day or two, only. They pose a greater risk to society and environment as they are unexpected and quick to happen. Therefore, people have less time to prepare for dangers. There are about 7 different type of flood. Did you know? WA, SA, VIC, NSW, TAS Southern states were encountered by floods.
The states were: That in August 1955,
Australia's... Oh really? ^ ^

yeah. YEP Apportion can happen among floods according to duration or location. These 3 classes of floods are in the duration
category . "Coastal floods" are along coastal areas by sea. These floods are caused by severe hurricanes or tropical storms and are also created by storm wind that push the water up and create high waves. Tsunamis are a contribution to Coastal Floods. This type of flood can also take place when volcanoes install vigorous and immense tidal waves in water.
"Arroyos floods" are created in stormy, wet conditions or seasons. Arroyos Floods are caused when a portion of time is filled with rain, maneuvering amounts of water into one place, the "arroyo" (also known as dry riverbed, originated from Spanish language.) In result, the water level rises and overflows, turning into a river, creating a flash flood.
"River floods" are what as known as the most common type of flooding. As said, when the actual amount of river is larger than the expanse of its capacity, the river deluges and flows beside the river.
"Urban floods" are a problem to urban cities because of their adjacency with places with high population. This type of flood is brought forth by not enough drainage in urban area. That is because there is lack of soil used for water storage, therefore all the rain, snow, etc, is needed to be in a different place such as surface water or sewage systems. Flooding is then caused when high amounts of intensive rainfall fills up too much water and excesses the capacity of the city sewage system or drainage canals, making an effect that is yucky. Water may come in through the sewage system, then come out ending up on the street depositing waste. heh heh These Floods are categorized by location XD Response to floods. again... How floods can be created. http://library.thinkquest.org/03oct/02054/floodtype.htm
- for types of floods Sources of information: http://www.ehow.com/how-does_5200486_do-floods-occur_.html http://www.wisegeek.com/what-is-an-arroyo.htm Floods are established in areas amidst water resources and the body of water. (Creeks, rivers, etc.)
The land or area between the water resources and the body of water is called a watershed.
Overflow of water, or flooding can occur when too much rain or snow melt excess the capacity of watersheds, resulting in an error. When a watershed works properly and decently, the water from melted snow or rain is either sponged up by the ground or sent down to the shed to fill a river, lake, etc. Floods can be connected and similar to each other. Some are which of roots or the start of a different flood. XD THE END In the end, floods suck anyway. Coastal ... small Arroyos http://www.floodsite.net/juniorfloodsite/html/en/student/thingstoknow/hydrology/urbanfloods.html
http://weather.about.com/od/u/qt/urban_flooding.htm Architect Industries in the Philippines have taken charge to architect and design buildings in which can withstand floods and other natural disasters.
Most places in Australia have also taken a good affect and have responded to flooding by having a clean up day. By doing that, Australians have lessen the risk of flooding due to pollution.
These are 2 examples of how countries have responded to floods, trying to fix, and upgrade their standards so that they can have more protection against this natural disaster.
