Great Artesian Basin groundwater flow model scenario outputs: GABtran model: Climate change

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 "Cdry.grd"", "Cmid.grd" and "Cwet.grd" show predicted hydraulic head for the year 2070 based on projections of future climate and the continuation of current rates of groundwater extraction


The files "Cdry-Base.grd", "Cmid-Base.grd" and ""Cwet-Base.grd" represent predicted differences between the hydraulic heads produced by Scenario C at 2070, and the modelled spatial distributions of hydraulic head for the year 2010 (Base scenario).


The files "Cdry-A.grd", "Cmid-A.grd" and "Cwet-A.grd" represent predicted differences between hydraulic heads for 2070 produced by Scenario C and the current climate and development scenario (Scenario A).

Statement

This data set is derived from outputs from 'climate change' scenario models based upon the GABtran groundwater flow model. These scenarios were developed based upon recharge scaling factors described by Crosbie et al. (2011; "Diffuse recharge across Australia under a 2050 climate: Modelling results", CSIRO report to the National Water Commission). These factors were used to scale modern (i.e. 2010) recharge over the period 2011-2070 in accordance with three climate change scenarios (i.e. dry, median, wet).
