Sydney Basin Aquifers (SBAs)

Sydney Basin Aquifers (SBAs)

The Sydney basin aquifers (SBAs) constitute a number of separate aquifers but within the same geological units, covering a surface of approximately 17,000 km2 (Cendón et al., 2009). Groundwater in the region supports irrigation and has been identified as emergency water supply for the Sydney area. This will be used as a pilot to assess other controls (i.e.: orography, rain shadows, etc.) and their effects on potential paleogroundwater climatic signals.
