Flash floods are a problem in Australia. These devastating forces of nature can cause extensive damage to property and can put lives in danger. The financial and psychological effects of a flash flood can take individuals and communities years to recover from. It is important that effective measures are put in place so that flash floods can be prevented. In the event of a flash flood, it is important that prior preparation minimises the damage to property and the potential loss of life.
There are dozens of reasons why flash floods occur. These reasons need to be taken into account so that the necessary steps can be taken to defend communities against damage. This helpful guide lists five of the main causes of flash flooding. Read on in order to find out more.
Blocked And Damaged Drains
Damaged drains which are cracked and overflowing will not be able to handle large amounts of water. Likewise, blocked drains in Perth which are clogged with debris such as leaves or rubble will be unable to channel water safely underground.
It is important that homeowners regularly have the pipes in their houses checked for any signs of damage or blockages. Local councils should do the same to the drains beneath a city’s roads. The regular maintenance and repair of pipes will mean that the risk of flash flooding is greatly reduced.

Parts of Australia are susceptible to sudden downpours which can trigger flash flooding. Canberra receives the lowest amount of yearly rainfall between major cities in the country. It is susceptible to sudden rainfall after weeks of dry weather which can result in floodwaters forming.
The worst recorded flooding disaster in Australia’s history occurred on June 24, 1852, when 89 people lost their lives in Gundagai, New South Wales.
Modern irrigation and drainage systems have become increasingly more sophisticated in order to deal with sudden downpours. These drainage systems allow rainwater to be collected in gutters and pipes before they have a chance to cause extensive damage. Rural areas have a higher risk of flash flooding from sudden rainfall because the quality of drainage is of a lower quality.
Damage To Man-Made Structures Such As Dams
Dams are designed to retain vast amounts of water for a variety of purposes. Commonly, water is retained in order to be used for hydroelectric power. These structures need to be carefully monitored for any signs of damage. Cracks in dam walls or structural collapses can lead to large quantities of water escaping and causing damage to nearby property. A detailed system of checks and balances need to be in place to prevent this from happening, and dam workers should report problems to superiors as soon as they are noticed.
Natural Disasters Such As Hurricanes Or Mudslides
Hurricanes or mudslides can occur flash flooding to occur as a knock-on effect.
Rising Global Temperatures
Global warming has the potential to increase the risk of flash flood in areas which are increasingly seeing rapid downpours after weeks without rain.
