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.

Projection is Albers equal area conic, with central meridian 143 degrees longitude, standard parallels at -21 and -29 degrees latitude and latitude of projection's origin at -25.
