摘要

Australia is synonymous with a challenging climate, as diverse as it can be extreme. The past decade alone has been punctuated by episodes of crippling drought, devastating bushfires, tropical cyclones and flooding rains that have caused unprecedented damage, major economic impact and tragic loss of life. In a country where almost 90% of the population lives in urban centers (Brown, 2009), the impacts of such climatic variability have been acutely felt in almost every major capital city. Desalination plants have been constructed as a new and essential component of water supply infrastructure in Sydney, Adelaide, Perth, Melbourne and Brisbane. While Perth, in Western Australia, continues to experience dry conditions and has recently commissioned a second desalination plant, other cities have since experienced above-average rainfall that has seen traditional water storages recover. In Brisbane, in the country's north-east, this occurred with devastating affect when Wivenhoe Dam, the city's major water storage and flood protection, spilled in January 2011, inundating much of the city.
