Hundreds of thousands of Queenslanders live on floodplains, often unwittingly until they are actually flooded. In the past 10 years floods in South East Queensland, Bundaberg and Townsville as well as elsewhere have brought into question urban planning decisions, building designs, emergency planning and flood mitigation strategies. Yet there continues to be pressure to put more dwellings in floodplains, often replacing existing development with higher density development. When councils say no, the courts may say yes. This presentation explores research around human responses to flood warnings, people’s attitudes to flood risk, recent court decisions and the presenter’s ideas on finding ways to sketch a line between acceptable, tolerable and unacceptable risk to life.
The 2004 Indian Ocean tsunami that devastated Indonesia, Thailand and Sri Lanka, brought about a heightened interest and focus into the science and disaster management for this type of hazard. In 2011, the Queensland Government commenced a project to better understand the potential tsunami hazards along the east Queensland coastline. The first stage undertook hydrodynamic modelling to examine the nearshore amplification along the east Queensland coast, identifying regions where the hazard was the greatest. The project indicated that the coast south of Fraser Island was at higher risk. Subsequent tsunami inundation modelling has been completed for Moreton Bay, Sunshine Coast and Hervey Bay.
This presentation will examine the tsunami hazard along the south-east Queensland coastline.
Challenges of long tunnels and underground spaces in the snowy mountains. Learn the place of major pumped hydro in Australia’s electricity mix.
Snowy 2.0 will supercharge the Snowy Scheme’s existing hydro-electric generation and large-scale storage capabilities. The fast-start, on-demand generation of pumped-hydro and Snowy 2.0’s massive storage capacity will be vital as more intermittent, renewable energy sources such as wind and solar come online and coal-fired power stations retire. Snowy 2.0 will add 2,000 megawatts of energy generation and provide 175 hours of storage for the National Electricity Market (NEM), enough to ensure the stability and reliability of the system during prolonged weather events, such as wind or solar ‘droughts’.
Snowy Hydro already plays a critical role in ensuring system stability and at times of peak demand, we keep the lights on. Snowy 2.0 will enhance our existing capability and ensure that we can continue to provide increased stability and security to the energy market well into the future.
The 2019 Townsville flood was a major flood event that occurred in the city of Townsville and surrounding areas. One of the worst natural disasters to ever impact the region, the event was caused by a slow-moving tropical low, situated north-east of Mt Isa. The system persisted for approximately one week with little deviation or movement, producing consistent heavy rainfall over the affected areas. Major flooding occurred across the Townsville region as a result.
Some Townsville suburbs, particularly Rosslea, Hermit Park, and Idalia, experienced major inundation. This resulted in a significant impact upon infrastructure such as the road, power, rail and water supply networks.
Multiple agencies assisted with the recovery, including the State Emergency Service (SES), Queensland Government, Townsville City Council, Australian Defence Force, Queensland Rail and Ergon Energy.
The focus for this presentation will be on the impact that the flooding event had upon local infrastructure in the Townsville area and work that went into assessing and evaluating damage and undertaking repairs.
In late October 2019, the Queensland Heritage Council reached a decision to enter the Mount Crosby Pumping Station Complex in the Queensland Heritage Register as a place of state-level significance.
The Queensland Heritage Register is a list of places that have cultural heritage significance to Queensland. Places listed on the register are considered important as they contribute to our understanding of Queensland’s history and heritage.
The Mount Crosby Pumping Station Complex extends across both the east and west banks of the Brisbane River, and is evidence of historic water management at the landscape level since the 1800s.
This presentation will showcase the significant engineering heritage landscape managed by Seqwater at Mt Crosby and beyond as part of the Brisbane water supply story, and the challenges and opportunities to protect and conserve working heritage sites.
The speakers will talk about:
Brisbane’s water supply story, including the Mt Crosby heritage landscape and beyond with a focus on some engineering challenges and lessons learnt
Challenges and opportunities in the management, protection and conservation of working heritage sites
Mt Crosby Flood Resilience Program: Planning large-scale works within significant heritage landscapes
Mt Crosby Eastbank WTP bank stabilisation project: Case study of risk mitigation in action
