Indicators of Catchment Condition in the Intensive Land Use Zone of Australia – Predicted 2050 salinity

\n\nIt should be noted that this data is now dated!\n\nThe indicator reflects the probability that a catchment will develop a\nsignificant salinity problem at some future time or continue to expand in an\nexisting one.\n\nIt is an indicator of hydrologic disequilibrium and is relevant across a range\nof scales.\n\nThe 2050 predicted extent of salinity was modelled by various state and\nterritory agencies for the National Land and Water Resources Audit, 2001.\n\nDifferent methods were used to estimate the extent so this national view of\npredicted extent is not consistent and open to errors.\n\nMost catchments in Western Australiaas southwest are predicted to continue\nwith substantial salt areas to 2050.\n\nSome increases are predicted for the southeast coastal catchments.\n\nCatchments in Western Australia that are predicted to have increased salinity\nproblems are the Esperance Coast, Albany Coast, Denmark, Kent, Frankland,\nShannon, Warren, Donnelly, Blackwood, Busselton, Preston, Collie, Harvey,\nMurray, Avon, Swan Coast, Moore Hill River basins.\n\nThe extent of salinity in Tasmania and Queensland is predicted to decline\nslightly, with no new areas identified.\n\nIn South Australia, NSW and Victoria salinity is predicted to worsen,\nincluding more areas of catchments throughout the Murray-Darling Basin, in\nsouthwest Victoria and in the upper southeast of South Australia.\n\nIn Victoria the catchments predicted to have increased salinity are Millicent\nCoast, Glenelg, Portland Coast, Hopkins, Otway Coast, Lake Corangamite,\nBarwon, Moorabool, Werribee, Maribyrnong River basins.\n\nIn NSW the catchment with a predicted major increase in areas of salinisation\nis the Castlereagh.\n\nData are available as:\n\n * continental maps at 5km (0.05 deg) cell resolution for the ILZ;\n * spatial averages over CRES defined catchments (CRES, 2000) in the ILZ;\n * spatial averages over the AWRC river basins in the ILZ.\n\nSee [further metadata](http://data.daff.gov.au/anrdl/metadata_files/pa_iccilr9ab\n__05321axx.xml) for more detail.\n\n
