Here are a few interesting things you can share with your friends about floods.

problems caused by floodsIn Australia, floods are the most expensive type of natural disaster with direct costs estimated over the period 1967-2005 averaging at $377 million per year (calculated in 2008 Australian dollars). http://www.chiefscientist.qld.gov.au/publications/understanding-floods/consequences.aspx

problems caused by floodsFlood losses in the United States averaged $2.4 billion per year for the last decade. Floods are the number one natural disaster in the United States. http://www.floodsmart.gov/toolkits/spanish/downloads/english/facts-and-figures.pdf

problems caused by floodsA physically defined route (path) where water or run-off passes into an outlet or terminus. (Terminus can be the ocean or bigger water body) This includes rivers, creeks, tributaries, stream or estuary. A waterway may be dry, but will soon be full of moving water when there are rains.

problems caused by floodsPeak water level / flood peak - The highest level that water in a waterway reaches during a flood. This is a measure of the size (or magnitude) of a flood.

RunoffRunoff – Each time there is more water on a piece of land than it can infiltrate the soil, the excess water will flow to find its own level. The excess water flow is what we call ‘Runoff” Sometimes the rains come down heavily and the soil (or earth) cannot absorb the water quick enough. This causes the rain water to flow as a runoff.

problems caused by floods
Never swim or play around in flood water. It may contain chemicals, bacteria and disease causing organisms. If your skin comes in contact with floodwater, make sure to wash it with soap and disinfected water because the contents are unknown.

problems caused by floodsCommunities particularly at risk are those located in low-lying areas, near water, or downstream from a dam.

problems caused by floodsBased on Floodsmart, a 2,000 square foot home undergoing 12inches of water damage could cost more than $50,000.

problems caused by floodsNever drive into a flooded roadway or drive through flowing water because just 2 feet of water can float a large vehicle and sway it away.

Flood watchSometimes, local emergency officers are able to tell if there is a possibility of flood during a rain or high tide at the shore. When this happens, they keep a close eye on events and inform the public about it. This is called a Flood Watch.

Flood warningA flood warning is when an official announcement is given (by TV, Radio, Text Message or Phone, Email or other means) of an impending flood or an already flood that has already occurred. A flood warning instructs people to move to higher ground or take immediate precautions to avoid drowning or to minimize damage to property.

What is a leveeLevee: A manmade structure to contain or prevent water from moving past a certain point.
