What effect did the Australia floods have on Australia?
It cost alot of money, and people died. But it made us smarter and stronger.

Although Australia is the second driest continent (with Antarcticabeing the driest as precipitation there is virtually nil), it canand it does flood in Australia - regularly. …Floods are one of themost common natural disasters in the country. This is because ofthe unique layout of the continent. Australia is a very flat country. Running down the eastern coast isthe Great Dividing Range, so there are the usual coastal plainsthere. To the west of the range are vast expanses of flat country,and when there is a lot of rainfall (which happens sometimesseveral times a year, and sometimes only every few years), therivers quickly swell and break their banks, sending massive floodsacross these great plains. Australia spends many years in drought, often caused by the El Niñoeffect. When an El Niño occurs, changes in sea surface temperaturescause a shift in air pressure which, in turn, can result inclimatic anomalies, such as severe droughts in Australia. Theseyears are punctuated by years of normal rainfall, but occasionally,Australia gets the opposite to an El Niño, which is La Niña. Thismeans that weather conditions, etc, are in reverse to those seenduring El Niño, and Australia experiences far more rain than usual.When this happens, many parts of Australia will see graduallyincreasing rainfall over the period of several months. The groundbecomes too saturated to hold any more water. This often occursduring the spring and summer season, which is also cyclone season.Add to the already super-saturated ground the effects of a cyclonewhich becomes a rain depression once it crossed the coast, and thescenario is one of excessive rainfall leading to the groundbecoming waterlogged. (This was the pattern that led to both theBrisbane floods of 1974 and 2011).
Three major types of floods include:. Slow onset floods - these occur gradually after there has been significant rain in a catchment area. Often, towns have plenty of warning… that such floods are coming, and have the time to create levee banks for protection. Charleville, in western Queensland, is prone to slow onset floods as the waters flow down the Warrego River from further upstream, where heavy rain has fallen. The water takes days or even weeks to go down. . Fast onset floods - these are also caused by heavy monsoonal rains, but water comes up more quickly, often trapping motorists trying to cross swollen rivers and isolating towns quickly, then just as quickly subsiding. . Flash floods - usually caused by thunderstorms and sudden downpours. these fill rivers and drains quickly, sweeping away people who try to cross. Flash floods subside very quickly.
Currently (January 2011), Queensland is suffering from massive floods across much of the state. Some 22 towns and a couple of cities have been fully or partially evacuated. …Some of the water is heading for the coast; some of it is replenishing the Darling River which, in turn, will flush out the Murray River to the south. The city of Rockhampton has been particularly badly affected. Other Queensland towns significantly affected include Emerald, Dalby, Chinchilla, Condamine, St George, Theodore, Bundaberg, Mundubbera and Warwick. Toowoomba experienced a devastating flash flood which then travelled down the range, hitting the towns of Grantham, Helidon, Murphy's Creek and Gatton. Many deaths were recorded in this area. The floodwaters then continued on to the Wivenhoe Dam which, due to being over capacity, resulted in flooding of the Brisbane River, which affected the cities of Ipswich and Brisbane. In western New South Wales, Bourke has been badly affected, and more towns will be affected as the floods move south. In northeastern NSW, Grafton and centres in the Northern Rivers area are being hardest hit.
75% of the entire state of Queensland has been affected by floods in some way. This includes from Rockhamptonl where floodwaters have remained for about three weeks. Centres… west to Emerald and south west to St George have been affected as well. In January 2011, the city of Brisbane has been inundated with the rising of the Brisbane River. In addition, the floodwaters have moved south, together with heavy rain, which has swamped parts of northern and western New South Wales, and northern and western Victoria. Even parts of South Australia have been affected.
It started on the 23rd of December 2010
Most of the floods in Australia happen in the northern more tropical areas because it receives the greatest amount of rain.
Very briefly the floods were caused by excessive rain, the ground not being able to absorb anymore water and the La Nina weather pattern.
Floods occur in all of Australia's states and territoriesperiodically. Floods are among the most common natural disasters inAustalia.
As of 28 January 2011, northwest Victoria is certainly still flooded. Swan Hill is the area currently under threat.
we are a huge land mass based in the middle of nowhere next to the largest body of water in the entire world and in qld we have the longest mountain range in the world as well… which is close to the coast... Combined with expected seasonal rain, high tides and cities and towns basing themselves around the water run offs and river mouths should we not expect this to never happen every now and then? Planes crash... Boats sink... Cars collide... Trains derail... The 6 main effects... Affected farms... Food prices... Roads... Government schemes & projects cancelled... International tourism... And insurance companies reinforcing why we shouldn't apply for your cover... Let us down and now see ure policies decline and a major investment structure drop as well... I hate to s a this but we need insurance companies for economic purposes...
Parts of Australia flood regularly. The most recent significant floods occurred between December 2010 and January 2011.
The Australian flood lasted for more than 40days
Many parts of Australia's eastern half and the north are flood-prone due to the numerous river systems and low plains throughout the region. The northern and eastern coasts ar…e also prone to summer cyclones (which bring heavy rains) and seasonal monsoonal rains. These rains can send large amounts of water across the northern plains, through Queensland's "channel country", which floods huge areas of land in north western Queensland. Another particularly flood-prone region is the Hunter Valley in New South wales.
