Variability of Extreme Climate Events and Impacts of Future Climate Change on the Streamflow
20 MAY 2022
12.00 PM - 1.30 PM

The aim of this research project is to develop a comprehensive methodology integrating hydrological models, spatial models and climate models under different scenarios based on the Generalised Extreme Value (GEV) model and explore the impacts of future climate change on the streamflow in Australia. This research study will analyse the hydrological response of streamflow of river basins under stationary and non-stationary conditions and calculate the metrological and hydrological drought indices for the baseline and future periods. Lockyer catchment of Southeast Queensland has been taken as a case study area as this region contains a mix of residential and agricultural areas with houses for water supply dams for drinking water. With the expected further increase in climate change, extremes, drought, and floods as well as their devastating impacts could be on the rise in the future in this region. Accordingly, there is a need to develop an integrated framework such as multi-model framework to cope with future extreme events. The proposed framework, which combines the hydrological model, climate model, GEV models under non-stationary assumptions, satellite data, machine learning technique and drought indices is an effective tool that helps decision-makers, state authorities and water planners to investigate adaptation strategies to cope with probable future changes. Further, the framework can be useful in determining the susceptibility of this region to extremes in the future and improving sustainable catchment management. It is expected that the outputs from this research study will serve as a useful resource for climate change effect assessments on water resource management in similar places.
