Abstract

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 rasters of spatial distributions of hydraulic head for the year 2070 that were output based on projections of future climate and projections of future groundwater extraction (Scenario D). For each climate change scenario there are three outputs: one for each modelled aquifer thickness (100, 150 and 200 metres). The subfolder "differences" contains rasters of differences between the spatial distributions of hydraulic head that were output by future use 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 5000m x 5000m For more information, please refer to Welsh WD, Moore CR, Turnadge CJ, Smith AJ and Barr TM (2012) "Modelling of climate and groundwater development. A technical report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment ". CSIRO Water for a Healthy Country Flagship, Australia. 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.
