Formatted abstract
Regardless of future emission, there is general scientific agreement that greenhouse gas emission has reached a level where climate change is foreseeable. Observational evidence indicates that over the past five decades, Queensland’s climate on average has become both warmer and drier. The primary question arises on: what is the likely future climate scenario for South East Queensland and what impacts could it has on runoff and water quality in Upper Brisbane and Stanley catchments; two of the important catchments as they are the major source of water supplies to South East Queensland.

This thesis documents a preliminary investigation to determine the likelihood that SimCLIM climate change scenario generator couple with E2 Catchment Modelling Toolkit can be used to investigate climate change impacts on runoff and water quality in the Upper Brisbane and Stanley catchments. By developing and assessing the procedures requires to couple both models and examining the projected future climate scenarios and its impacts on Upper Brisbane and Stanley catchments, this thesis presents the likely ranges of future conditions for Upper Brisbane and Stanley catchments which are based on the upper range of wet and dry climate change scenarios combined with the most extreme assumptions of future greenhouse gas emission.

The findings of this thesis were found to be beneficial in providing crude overview of coupling climate change scenario generator to a hydrological model. SimCLIM was found to be only
useful in providing the percentage change per degree global warming value which then can be used to project future climate scenario by utilising the constant or daily scaling method. It was summarised that coupling SimCLIM and E2 Catchment modelling Toolkit does not have any significant advantage over other software that have been used in previous researches.

The projected future conditions of Upper Brisbane and Stanley catchments presented should only serves as indication that the uncertainties surrounding possible changes to mean annual and monthly rainfall are large. With changes suggesting that significant increases or decreases in precipitation and runoff are possible.
