Improving water benefits
The Coorong and Murray Mouth region is one of the best habitats for waterbirds in Australia. However, following a decade of low to no River Murray inflows, the region is now degraded, with significant declines in fish and bird numbers.
The CLLAMMecology project has developed a two-step approach to help plan future management interventions to rehabilitate this region.
The first step of this approach is to evaluate future climate and management intervention scenarios using a hydrodynamic model to predict future water level and salinity regimes, the two key ecosystem drivers in this region.
These water level and salinity predictions can be made for the length of the Coorong (~110 km) at decadal or longer time-scales as a function of River Murray discharge over the Lower Lakes barrages, connection to the sea via the Murray Mouth, and Upper South East Drainage discharge.
This hydrodynamic model is practical to use because it can be directly incorporated into existing models forecasting River Murray discharge over the Lower Lakes barrages.
The second step of the approach is to evaluate ecological responses to changes in water level and salinity. Several tools have been developed, including models that evaluate the change in the distribution of key fish and bird species, of key habitats (such as mudflats), or of whole ecosystems.
An overview of the outputs from the project and their potential applications are presented in the final summary report. These tools are now available to help plan management intervention in the region.
