  • This data release contains accurate positional data for groundwater boreholes in terms of horizontal location as well as elevation of the top of casing protectors. Twenty-four boreholes located in the Nulla and McBride basalt provinces have had DGPS survey results compiled and are presented. Using 95% confidence intervals, the horizontal uncertainties are less than 1.2m and vertical uncertainties less than 0.9m. These results are a substantial improvement, particularly on the uncertainty of elevations, and as such allow water levels need to be compared between bores on a comparable datum, to enable a regional hydrogeological understanding. Quantifying the uncertainties in elevation data adds robustness to the analysis of water levels across the region rather than detracting from it.

  • 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.
