Abstract :

Eastern Australia was subjected to widespread rainfalls during the summer 2010-2011. Between the end of November 2010 and January 2011, about 75% of the State of Queensland was affected by some major flooding. Both large-scale flooding and flash floods took place causing substantial loss of life. In this presentation, the speaker will share his personal experience and observations of the floods and flooding in Central Queensland, South Queensland and South-East Queensland. He will present an unique series of field measurements conducted in the Brisbane CBD during the major flood of the Brisbane River in 12-14 January 2011. The inundation of the urban environment led to some complicated flow motion associated with significant sediment fluxes. The flood water sediment deposits were predominantly silty material with a median particle size about 25 μm. The results highlighted the large suspended sediment loads and fluctuations in the inundated urban setting. The field deployment was conducted in challenging conditions highlighting a number of practical issues during a natural disaster, including the stability of individuals in floodwaters.
