Modelled groundwater levels from 2010 to 2070 used to estimate the impact of climate change and future groundwater resource development on groundwater levels in the Cape York area of the GAB. The modelling considered different scenarios of climate and groundwater development: Scenario A (historical climate and current development); Scenario C (future climate and current development) and Scenario D (future climate and future development). The future climate scenarios included the wet extreme (wet), the median (mid) and the dry extreme (dry). This data set contains spatial data that were created from the outputs from climate change scenario models using on the Cape York groundwater flow model. The subfolder "heads" contains various raster grid representations of spatial distributions of hydraulic head for the year 2070 that were output by the respective climate change scenario model, based on projections of future climate. For each climate change scenario there are three outputs: one for each modelled aquifer thickness (100, 150 and 200metres). The folder "differences" contains various raster grid representations of differences between the spatial distributions of hydraulic head that were output by climate change scenario models and by either (a) the respective "A scenario" model or (b) the respective "Base scenario" model (the modelled hydraulic head for the year 2010.) 'No data' value is 1e30 for heads rasters, -9999 for differences rasters Cell size is 5000 m x 5000 m This data and metadata were produced by CSIRO for the Great Artesian Basin Water Resource Assessment.

LINEAGE (Continued from Lineage field due to space constraints) METHOD: Data covering the areas of Upper Darling, Lower Namoi was supplied by the NSW government. Contours in the Macquarie region NSW were interpreted from the Cenozoic isopachs taken from Macaulay, S. & Kellett, J. (2009) Lower Balonne Deep Lead tertiary isopach contours captured from a National Action Plan for Salinity and Water Quality report (Chamberlain, T. & Wilkinson, K., 2004; Kellett et.al. 2004). Isopachs in the southern portion of the GAB were captured from the Cainozoic Structural Features page 22 of Palaeogeographic Atlas of Australia: Cainozoic (Langford & Wilford, 1995) Isopachs over the Poolowanna Trough and Cooper Basin region were taken from Tertiary Stratigraphy and Tectonics, Eromanga Basin (Moussavi-Harami, R. & Alexander, E., 1998) Isopachs in the central Eromanga Basin, Queensland came from Senior 1978. Position and boundary of the Condamine Basin from Klohn, Crippen & Berger, 2011 - feasibility of injecting CSG water into the central Condamine Alluvium - Summary. Report prepared for department of Environment and Resource Management, Queensland, 8p. Isopachs came from the Cainozoic Structural Features page 22 of Palaeogeographic Atlas of Australia: Cainozoic (Langford & Wilford, 1995) Drill-hole data sourced from PIRSA (2007) and GABLOG (Habermehl, 2001) databases, Gibson et al 1974, and well completion reports from GSQ (Queensland Department of Natural Resources and Mines, 2012). Data were used to interpolate a surface using the Topo to Raster tool in the ArcGIS Spatial analyst toolset and the resulting raster was clipped to the Great Artesian Basin Water Resource project boundary. Isopach contours were generated from the raster, using the Contour tool in the 3d analyst toolset in ArcGIS. METHOD

The revised Great Artesian Basin Jurassic-Cretaceous boundary was produced by the Great Artesian Basin Water Resource Assessment (GABWRA) . This boundary is modified from that of Habermehl and Lau 1997 and incorporates the revised boundary from the South Australia Great Artesian Basin (Eromanga Basin) Hydrogeological map 2012. Modifications made to sections of this boundary as part of the GABWRA include major revisions to the Surat and Clarence-Moreton Basins boundary; southern part of the Coonamble Embayment; NW Queensland boundary within the Lawn Hill and Westmoreland 1:250K map sheet areas. The dataset includes boundaries of basement inliers within the GAB Note: Habermehl and Lau 1997 boundary included Triassic GAB formations in Queensland which were not considered by the GABWRA. Data is available in polygon format. REFERENCE: Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.
