It is essential to develop a long-lead streamflow forecast system for providing the prior signal for possible floods. Climatic variabilities such as oceanic-atmospheric global oscillations may possess tele-connectivity with Australian rainfall-runoff. This study identifies an ocean-atmospheric region connected with Australian rivers streamflow. By utilizing its persistence capacity, statistical and machine learning-based forecast models are developed, predicting inter-annual streamflow forecast of Australian river flows. This outcome will be beneficial for future water planning and mitigating flood risk.

Investigating the linkages between Indo-Pacific Ocean SST, Z500 climate variability and Tasmanian seasonal streamflowShams, Md Shamim; Anwar, Faisal ; Lamb, Kenneth (2017)Seasonal floods occur predominantly in Tasmania at any time of the year (STORS, 2006). Improved streamflow predictability can be helpful for better Tasman seasonal flood forecasting and flood management in the rise of ...
