SPATIAL DISTRIBUTION OF FLOODS
Floods can occur anywhere in Australia, however they are most common in the north of Australia as well as the gulf of Queensland in the summer season. Floods in Australia often occur along rivers in low-lying areas of Australia, such as the Brisbane River. This is usually caused by prolonged periods of rain, which overflows the banks of particular rivers. These types of floods however can cause horrendous or even unrepeatable damage as the floodwater can flow down through low-lying regions.
They can also extend for thousands of square kilometers joining with several rivers at a time and can last for weeks, however they often have warnings months in advance. In regions of high mountain ranges and coastal areas, flooding’s can occur rapidly within a matter of minutes with sometimes no warning at all. These floods can occur anywhere when there is a relatively short intense rupture of rain often caused by thunderstorms. In these events the drainage system cannot cope with the vast amount of downpour of rain and as a result the systems begins to burst and overflow.
