The Brisbane 2011 Floods

The Brisbane Basin consists of 14 major river basins and sub-basins in the southeastern part of Queensland Province. The Brisbane River Basin covers an area of ​​about 14000 square kilometers and is the largest basin in this area. The Brisbane River is also the longest river in the southeastern part of Queensland, 309 kilometers long. In the catchment area there are several small dams and two big dams, Somerset and Wivenhoe. Wivenhoe was designed to prevent future floods and was completed in 1984. Figure 1 shows the Brisbane River Basin. It also includes rivers flowing into related rivers and rivers.

I lived in Brisbane in 2011 as the southeastern part of Queensland was hit by a tragic flood. At the end of the world's worst flood in Toowoomba and the Rocker Valley, 21 people died, reaching 150 mm in 2 hours, hit Rockwell Creek. More than 18,000 houses in Brisbane and surrounding areas were flooded with floods of varying degrees. I will not forget to clean up my friend Cheryl 's house, his house was completely submerged (above the roof). She is not insured, but she has to completely rebuild it. Cheryl did not know that her house was at risk of floods; no one told her. During the flood, she did not get enough warning time to remove valuable valuables and pictures.

In Brisbane, flooded in 1974, I have many local knowledge about this incident. However, the population growth rate of Brisbane has also doubled, and fortunately many new residents are not aware that Brisbane is built on floodplains. As a result, when floods occurred in 2011, many people were alert, but that is not the case. I lived in Brisbane in 2011 as the southeastern part of Queensland was hit by a tragic flood.
