The model developed by PhD candidate Fiona Paton, with supervisors Professor Graeme Dandy and Professor Holger Maier, should help water supply managers plan for future water security despite the uncertainty surrounding the impacts of climate change.
“Urban water supply is closely linked with climate variables, so climate change is expected to have a major impact on urban water security,” said Ms Paton. “Rainfall is obviously particularly important in determining water supply, but there is considerable uncertainty about how rainfall patterns will be affected by climate change.”
The researchers have developed a method to incorporate rainfall projections under a range of possible climate change scenarios into an urban water supply model. The model makes use of multiple probability-based daily rainfall sequences combined with historical rainfall data.
“Water supply managers are struggling to revise future water plans as they seek to take into account the likely impacts of climate change on future water security,” said Ms Paton.
“This is made more difficult by lack of agreement surrounding various global climate models and emissions scenarios, as well as the need to balance various conflicting objectives of water supply system planning.”
“We hope this model will help water managers estimate some of the climate change effects on supply security.”
In the paper ‘Sensitivity of Urban Water Security based on various global circulation models and emission scenarios’, the researchers applied their new approach to Adelaide’s Southern water supply system to the year 2100 in a case study including alternative water sources. This research won best paper award at the recent Engineers Australia’s ‘Practical Responses to Climate Change’ conference.
The future Adelaide supply system includes reservoirs fed from catchments, water pumped from the River Murray, household rainwater tanks, stormwater reuse schemes and the desalination plant.
The researchers, who are all part of the eWater CRC, said that recent moves towards diversification of water sources and demand management were commendable but there was a need for a more rigorous scientific approach as climate change further threatens supplies.Media Contact:

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
