The Groundwater Flow Systems Framework is a powerful support tool, developed to guide investment decisions for salinity management. A powerful support tool - Groundwater Flow Systems Framework - has been developed to guide investment decisions for salinity management. This full report and its companion summary report (PK030627), describe how the Framework can aid regional natural resource management groups in identifying appropriate salinity management options. They outline how results for well understood catchments can be extrapolated to other catchments where a similar groundwater flow system operates. Published by the Murray Darling Basin Commission
