Flood

South Australia has a dry climate but many parts of Adelaide and the state can flood. Flooding is one of the most damaging natural disasters for our State’s economy.

The highest rainfall In South Australia occurs in the winter months but floods can occur at any time. Flooding can be caused by rivers, storm water, dam release or a high tide combined with a storm surge on the coast.

Flooded road

Flash flooding, rapid flooding after heavy rainfall, is often difficult to forecast and can occur with little warning. It is more likely to happen in urban areas due to large areas of roofs and roads which make the water run off quickly.

Rising sea levels and the increasing number of people living in urban parts of the floodplain increases the risk of flooding in urban areas.

Climate change is expected to increase the intensity of rainfall events.
