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 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). The raster grids "Ddry.grd", "Dmid.grd" and "Dwet.grd" show predicted hydraulic head for the year 2070 based on projections of future climate and future development. The grids "Ddry-Base.grd", "Dmid-Base.grd" and "Dwet-Base.grd" represent predicted differences between the hydraulic heads produced by Scenario D at 2070, and the modelled spatial distributions of hydraulic head for the year 2010 (Base scenario). The grid "Dmid-Cmid.grd" represents the difference between the 2070 spatial distributions of hydraulic head that were produced by Scenario D (mid) and Scenario C (mid) 'No data' value is 1e30 Cell size is 5000m x 5000m This data and metadata were produced by CSIRO for the Great Artesian Basin Water Resource Assessment.

This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 75830. METHODS (continued from Lineage field): Contours were hand drawn from point water level data. Groundwater water levels along rivers with high EVI values were assumed to be 10m below ground. This information was used to interpret groundwater level contours where borehole water level data was absent. In areas of sparse data coverage the 3 second DEM was used to constrain contours below ground level. SA water levels were corrected for density effects due to salinity (in excess of 100,000 mg/L TDS in some bores in the Eyre Basin) but all others were uncorrected because salinity data were not available. Density corrections for the watertable are not deemed to be an issue outside of the SA portion of the GAB. Remote sensing studies of Enhanced Vegetation Index (EVI) were also used in the interpretation to provide water level information along certain rivers (refer to data set "Watercourses used to calculate riparian evapotranspiration loss from the GAB") where there were no boreholes. The hand drawn transparencies interpreted by Jim Kellet were scanned into a 2bit tiff file format. Scanned images were then rectified within ArcGIS and vectorised into linework using the ArcScan toolset to produce the polygon dataset Linework and were attributed with a contour value within the field "height", as well as a DESCRIPTION of the line TYPE in the field "descript". The grid surface was created using the Topo to Raster tool in the Spatial Analyst toolset from the values within the "height" field and clipped to the Revised Great Artesian Basin boundary and GEODATA TOPO 250K coastline. Note: data used to compile this map was a combination of the most recent available water level measurements (as at 2011), water level measurements at the time of drilling or the first water cut reported in drillers logs.

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
