摘要: A number of previous studies have identified changes in the climate occurring on decadal to multi-decadal time-scales. Recent also revealed variability modulation magnitude El Nino–Southern Oscillation (ENSO) impacts rainfall and stream flow Australia other areas. This study investigates drought risk by analysing performance a water storage reservoir New South Wales, Australia, during different epochs defined using Inter-decadal Pacific (IPO) index. The is analysed under three adaptive management techniques these are compared with current ‘reactive’ practices. results indicate that IPO both frequency ENSO events has effect reducing elevating confirm techniques, based forecasts, can improve security become significantly more important dry epochs. These marked implications for improving reservoirs.
