MBC Groundwater model layer boundaries

## **Abstract** \n\nThis dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. \n\n\n\nThis layer defines the extent of the OGIA groundwater model flow boundary for each of the model domain layers.\n\n\n\nThe layer number for each shapefile corresponds to the model domain layer of the QWC regional groundwater flow model for the Surat and southern Bowen Basin, produced for the Underground Water Impact Report on the Surat Cumulative Management area (refer History).\n\n## **Purpose** \n\nThe dataset was developed to describe the geological extent of the formations representing each of the layers in the regional MODFLOW groundwater flow model of the Surat Basin. The purpose of these layers is to define the model extents for the respective formations as represented in a number of Bioregional Assessment products for the MBC subregion.\n\n## **Dataset History** \n\nThis dataset defines the geological extent of the OGIA groundwater model flow boundary for each of the groundwater model layers that were as devised for the model.\n\n\n\nLayer 1: Central Condamine Alluvium Groundwater model\n\nLayer 2: Rolling Downs Group including the Griman Creek, Surat Siltstone, and Wallumbilla Formation\n\nLayer 3: Bungil Formation and Mooga Sandstone\n\nLayer 4: Orallo Formation\n\nLayer 5: Gubberamunda Sandstone in the Surat Basin and Hooray Sandstone Equivalents within the Eromanga and Carpentaria Basins\n\nLayer 7,8: Springbok Sandstone and represents layers seven (7) and eight (8) in the model\n\nLayer 10: Walloon Coal Measures of the Surat Basin and the Injune Creek Group of the Eromanga Basin\n\nLayer 12: Aquifer formation within the Hutton Sandstone and Marburg Sandstone\n\nLayer 13: Evergreen Formation\n\nLayer 14: Precipice Sandstone in the Surat Basin and Eromanga Basins\n\nLayer 15: Moolayember Formation\n\nLayer 16: Clematis Sandstone\n\nLayer 17: Rewan Group\n\nLayer 18: Bandanna Formation within the Surat and southern Bowen Basin region\n\n## **Dataset Citation** \n\nQueensland Office of Groundwater Impact Assessment (2012) MBC Groundwater model layer boundaries.
