What did we learn from the Lockyer Valley 2011 flood? Lessons and Opportunities from the Big Flood project
The River Basin Management Society is pleased to host this seminar with Associate Professor Jacky Croke in Northern NSW. After recent major flooding in the Northern Rivers region Jacky will share her findings from the Australian Research Council (ARC) Linkage Project in the Lockyer Valley entitled ‘The Big Flood: will it happen again?’
Six years ago on the 11th of January 2011 an unprecedented catastrophic flood event unfolded in the Lockyer Valley in south east Queensland, one of Australia’s fastest growing regions in terms of population and infrastructure. Rapid flood waters spilled out across the floodplains and moved downstream and throughout the Brisbane River catchment inundating the capital’s CBD and inner suburbs. The 2011 flood was reported in the media as ‘biblical’ and extreme in its magnitude and is estimated to have cost the Australian economy ~ $6B. This presentation reviews several key lessons and some exciting opportunities emerging from an Australian Research Council (ARC) Linkage Project entitled ‘The Big Flood: will it happen again?’ (www.thebigflood.com.au) which involved collaboration between Universities and state industry partners. The presentation focusses on three key themes (i) The role of Geomorphology in Flood Risk Management (ii) Extending the flood record through palaeoflood reconstruction and (iii) reducing uncertainty in flood frequency analysis- the future of flood risk management in Australia. Given the likelihood of increasing rainfall extremes in the future, it is critically important we start using this information to better prepare for more frequent extreme floods. These findings represent a good starting point to deepen our understanding and approaches to estimating flood risk.
Come and enjoy a drink in the bar from 5.30pm. The seminar will commence at 6 pm.
