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).
