Potential hydraulic interconnection at the base of the Great Artesian Basin

Polygons representing a qualitative estimate of the potential for hydraulic interconnection between the base of the Great Artesian Basin and top of underlying basement units. This dataset is derived from the 'Hydrogeological basement units in contact with the base of the Great Artesian Basin' dataset (Geoscience Australia, catalogue #75910, 2013) and 'Base Great Artesian Basin hydrogeological units in contact with basement' dataset (Geoscience Australia, catalogue #75911, 2013). It is used to identify potential hydraulic interconnection between the Great Artesian Basin and basement units.Data is available as polygons in Shapefile formatThis GIS data set was produced for the Great Artesian Basin Water Resource Assessment and used in Figure 3.6 of Smerdon BD, Ransley TR, Radke BM and Kellett JR (2012) Water resource assessment for the Great Artesian Basin.
