Connectivity of the Ballarat Water District with regional river systems

Systems analysis reveals challenges of climate change on linked towns and irrigation districts connected to Murray Darling Basin

Presentation by Dr Peter Coombes and Dr Michael Barry at the Climate Adaption 2018 on Thursday 10 May in Room P3, 13:30 15:00, at Crown Promenade South Bank Melbourne.

This paper presents systems analysis of climate change and population growth scenarios, and management options for the Ballarat region of Victoria which is dependent on groundwater and bulk water allocations from the Moorabool, Campaspe, Goulburn, Loddon and Yarrowee River catchments, and includes towns and irrigation districts. Detailed local inputs, such as demographics, land uses and human behaviour, and linked water supply, sewage, stormwater, economic and environmental considerations, were utilised to build systems analysis based on local scale behavioural inputs (bottom up) rather than traditional analysis of water resources based on regional scale assumptions and averages. This approach was able to reproduce historical water cycle behaviours and revealed the economic trade-offs created by climate change, high population growth and management options.

Is zero afflux the question or answer to better flooding outcomes?

Presentation by Peter J Coombes and Andrew Allan at HWRS 2022: Is zero afflux the real challenge or solution for better flood management? It is vitally important to establish science and legally based rules for fair administration of the objectives and exploration of options that respond to flood risks. Otherwise, there will be a substantial administrative burden for marginal benefit. Our professionals and agencies need to be prepared for a different and challenging future, and our methods need to be fit for purpose from a whole of society perspective.
