Understanding the frequency and causes of extreme flood events is crucial for social and economic planning and environmental protection. SEQ has one of the fastest growing populations in Australia; currently around 2.8 million people, and expected to increase to ~4.4 million by 2031. The associated expenditure on infrastructure is expected to exceed $100 billion. This overall goal of this project was to contribute to the improved understanding, prediction and management of extreme flood events in the Lockyer Valley and broader SEQ region.

Project overview

This project came about as a direct appeal from Industry in the recognition that current understanding of flood magnitude and frequency, geomorphic impact and catchment management is inadequate to safe guard key human and natural resources.

Major aims

  • Reconstruct a time series of major flood events for Lockyer Creek extending back more than 1000 years.
  • Predict river channel and floodplain geomorphic susceptibility to floods in the Lockyer Valley and locate areas of high risk.
  • Incorporate research findings into climate change predictions, water quality protection and river management in Australia.

Partner organisations

The partner organisations of Queensland Government's Department of Science Information Technology and Innovation, Seqwater and Lockyer Valley Regional Council represent leading agencies in natural resource management, water quality and ecosystem protection, reflecting the need for a comprehensive and effective approach to the prediction of flood risk and geomorphic response.
