Flood: a flood is an unusual accumulation of water that overflows from rivers, lakes or the ocean into the land that is not normally covered by water.
How often do floods occur in Australia? How often floods occur depends on the area that we are looking at. For example some countries are prone to flooding and floods occur on a regular basis, an example is Bangladesh. Australia on the other hand is the driest country in the world. Despite this parts of Australia, often along the east coast and northern Queensland, are susceptible to flooding and they occur almost on an annual basis.
