Project: Murray–Darling Basin Sustainable Yields 2 (MDBSY2)
This report documents river system modelling to inform understanding of climate change impacts on the water resources of the Murray–Darling Basin (MDB). To do that, it documents the model development process, results of that modelling and detailed analysis of combinations of model scenarios that consider historical and plausible future climate conditions. Through the hydroclimate scenarios, model parameters, and the different planning contexts of without development (WoD), June 2009 and Basin Plan full implementation (BPFI), the model results are presented to help understand the resultant impacts from tributary rivers to downstream systems.
This report characterises climate impacts on:
- inflows across the Basin
- water balances within illustrative river valleys in the northern and southern Basin to show impacts on different water resource flow components
- flows through the MDB in both northern and southern Basins
- end of system flows
- availability of water for different uses
- storage behaviours under future climates
- changes in low flow periods.
This report is therefore the culmination of a body of modelling work to provide a whole of Basin insights around the possible impacts of future hydroclimates on river system outcomes for the MDB.
