World Floods



Beginning in late 2010 and early 2011, a series of floods have devastated certain areas of the world, most notably Australia and Rio de Janeiro. In December 2010, a great flood hit the state of Queensland, Australia, including its capital city, Brisbane. The floods forced the evacuation of at least 70 towns and over 200,000 people were affected. The December 2010 Gascoyne River flood was the one of the most severe floods to ever take place along the Gascoyne River in Western Australia. It was triggered by record-breaking rainfall, amounting to over 6,000% of the monthly mean in just four days. The flood caused widespread damage in the region, most notably the coastal town of Carnarvon.
A high intensity of rainfall between January 12 and 14, 2011, caused major flooding across much of the western and central parts of the Australian state of Victoria. The question has been raised. When will the rain stop? Queensland Treasurer Andrew Fraser said it is not possible to put a figure on the damage, but a rough estimate is currently putting lost revenue from Australia’s GDP at about A$30 billion. The floods damaged a large portion of Australia’s coal mines and cotton plantings, among other resources. The 2010 La Niña weather pattern, which brings wetter conditions to eastern Australia, was the strongest since 1973.
Record or near to record sea surface temperatures were recorded off the Queensland coast in late 2010. The month of December, 2010, was Queensland’s wettest on record. 2010 was the Australian continent’s third wettest year ever. Communities isolated by floodwaters have experienced food shortages, and a rise in the cost of fruits and vegetables. On January 11, the Wivenhoe Dam in South East Queensland filled to a level equivalent to 191% of its supply capacity. The dam can hold the equivalent of 225% of its supply capacity. As of January 14, 2011, 30 deaths have been attributed to the Australian floods, 15 of which are from the Toowoomba and the Lockyer Valley area. Additionally, 14 people are listed as missing.
Starting on January 11, 2011, a series of floods and mudslides struck the Mountainous Region in the Brazilian state of Rio de Janeiro. The floods have caused at least 763 deaths so far, including 367 in the Nova Friburgo area and 310 in the city of Teresópolis. In a 24-hour period between January 11 and 12, 2011, this area of Brazil registered more rainfall than was expected for the entire month. Following the downpour, many areas in the region flooded. The disaster caused widespread property damage. Around 2960 people had their homes destroyed. The Brazilian local media has claimed that the combination of floods, mudslides and landslides in Rio de Janeiro has become the worst weather-related natural disaster in the country’s history. However, a similar flooding event occurred in 1967 when 1,700 people lost their lives.
