In 2010, ORC developed a groundwater model to inform water management in the Lower Tarras, Bendigo, Lindis Alluvial Ribbon and Ardgour Aquifers (Houlbrooke, 2010). The model was used to set allocation limits that provided for both water reliability for water users and protection for the aquifers and connected surface water bodies to ensure allocation did not result in adverse environmental outcomes.

With newly acquired information gathered since 2010, and significant land use changes in the area, it is timely to review the legacy groundwater model and update our understanding of the aquifers systems. Through model development and appropriate predictive scenario modelling the successful applicant can help us understand water reliability and aquifer vulnerability to support resource management and allocation decisions.
