 * //__FLOODS FOCUS QUESTIONS__//**

[|**http://pictures.aol.com/galleries/tags/flood**] http://www.fema.gov/kids/p_fld.htm

These are some ways floods are caused.**
 * 1.** **__What causes floods?__


 * Alot of rainfall (from cyclones or hurricanes)
 * Rivers rising
 * Ice melting
 * Tides due to the the moon
 * Tsunamis


 * Man**-**made floods.**

Some floods are artiificial or man-made. Such as if a dam fails. If the dam is poorly made or built in a place where earthquakes and landslides occour, the dam will break and the water floods the land.
 * 2. __What significant floods and those caused by humans have occured in the recent times__**
 * __and where__**
 * 1893 in Queensland Brisbane the Brisbane River banks broke and they washed away the Albert Railway bridge at Indrroopilly
 * 1954 in New South Wales. Over raining was the cause and water flooded houses at great speed
 * For at least 5000 years the Egypt Nile river overflowed it brought silt from up the river that is used for fertile soil
 * 1973 in the Northern Territory Rivers and stagnant pools over flowed. No distruction occurred but a good flow of water to arid desert. So the flood was good.

Floods can affect the community by going into peoples houses which means the council will have to pay for it. It also means that the people living in the house will not have a place to live for a while. If someone is a farmer and a flood ruins their land, they won't have any crops to grow. It can also drown their farm animals. also if we vhave drinking water in a dam, sea water can go into it which means we can't drink out of it. W**hich is a real pain!!!!!**
 * 3.__How do floods affect the community where they occur__**


 * 4.__What assistance is avalible to someone following a flood__**


 * The S.E.S
 * An Ambulance
 * The Army
 * Council
 * A Thearipest
 * The Police

These are some of the ways
 * 5.__How can floods be prevented and their effects reduceed__**


 * Drains**-
 * To stop drains flooding you need to install Antiflood Barrier. It will stop water almost completely. The lower drains need more action, these levels will always be effected.**


 * Bath-**
 * If you have a bath situated on the ground floor then that would be the next affected point of entry. Logically, the lower the discharge point, the lower the seepage. Some products will seal most drains, including showers and washing machines. Once again this will not be necessary if the manhole is plugged.**


 * Basements-****.**
 * these are some of the signs that you need to look for**
 * **Has your basement been adequately tanked? If not, what is the porosity of the ground?**
 * **Do you have cracked or damaged drains?**
 * **There are many, many more factors that can also take effect.**
