CLIMATE CHANGE IMPACT ON ROUS WATER SUPPLY

摘要

Climate change poses significant risks to the security of water resources in many parts of Australia. This study investigated the implications for secure yields of a regional water supplier in NSW. The aim of the study was to estimate future secure yields, using the Integrated Quantity and Quality Model (IQQM) and a range of climate change scenarios, to identify the most appropriate time horizon for making new investments in infrastructure. The assessment concluded that, when taking into consideration impacts of global warming, the need for a new source will be most likely after 2018, consequently planning needs to commence in 2008.
