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).
This data set contains spatial data that were created from the outputs from the "A scenario" model and the "Base scenario" model, both of which were based on the GABtran groundwater flow model. The raster grid "A.grd" represents the spatial distribution of predicted hydraulic head for the year 2070 produced by the "A scenario" model. The raster grid "Base.grd" represents the modelled hydraulic head for the year 2010. The raster grid "A-Base.grd" represents the difference in predicted head from 2010 to 2070.
