Work by the GllMORE project on the SWslopesof New South Wales has established a new role for airborne geophysics and geological systems interpretation in the battle againstAustralia’sold enemy- salinity.Collaboration between AGSO, CSIRO’s Divisionof Explorationand Mining, and the Bureau of Rural Sciences has developed our understanding of how airborne geophysicscan be used,to map the patterns of salt, material types and water. These patterns lend insight to the movement of salt and water through the landscape.Calibration of the airborne data by drilling enablesus to construct a 3D framework which, in turn, is the basisfor modelling the rate of delivery of salt to rivers. land use options and feasible engineering interventions to arrest salinity can then be tested. This capacity is the foundation of the National Action Plan for Salinity and Water Quality.
