Improving reservoir management to overcome climate effects of changing water levels - National Industry PhD Program

This project addresses the impact of water level fluctuations and flooding on reservoir water quality. By quantifying the ecological and water quality impacts of vegetation regrowth during droughts and subsequent inundation, the research will provide insights into managing reservoirs under climate change conditions, ensuring reliable drinking water and supporting ecosystem processes.

We know little of how water level fluctuations and flooding impact reservoir water quality. These are impacted by climate change such as by floods and droughts (which are both becoming more extreme) and reservoir management can mediate some of these effects with suitable knowledge. This project will address this knowledge gap and quantify the ecological and water quality impacts from reservoir level fluctuation on vegetation that regrows during droughts and is subsequently inundated with flooding. Whilst many of these lakes drain and fill over multi-year cycles, it is largely unknown the effects this may have on water quality. Flooding events may trigger poor subsequent water quality impacting drinking water. Conversely, it is possible that some plant species that re-grow may be beneficial for water quality and support important ecosystem processes. Improved management through knowledge gained in this project will help better manage our important water reservoirs.

In this project you will work closely with Industry (WaterNSW) and spend a considerable amount of time working within their organisation.
