A better understanding of groundwater flow systems will help us manage salinity in the Murray-Darling Basin. A 1:1,000,000 map of the main groundwater flow systems relevant to dryland salinity in the Murray-Darling Basin has been produced. The hydrogeological characteristics and salt stores vary across these groundwater flow systems affecting the risk of salinity in the near-future and the capacity to modify this risk. In collaboration with the regions, similar coverages of some upland parts of the Murray-Darling Basin will be produced at 1:250 000, more relevant to land management decisions. Click on the map for a large scale map of groundwater flows in the Murray-Darling Basin. Warning: This is a large file (520Kb) and will take some time to load.

The type of groundwater flow system is one of the main determinants of the choice of salinity management whether it be biological recharge reduction, engineering options for managing shallow water tables, or saline agriculture..."
