10.3 Recharge from landscape
Supporting information
The volume recognised in the water accounting statements (10,764 ML) represents the volume of groundwater estimated to recharge the sedimentary and fractured rock aquifers in the region during the 2012–13 year.
Quantification approach

Method
The volume of groundwater recharge is estimated to be equal to the extraction from groundwater in the region during the 2012–13 year.
Assumptions, limitations, caveats and approximations
It is assumed that aquifer recharge is equal to total groundwater abstracted; however, it is likely that this volume is an under-estimation of actual recharge.
An expansion of the monitoring bore network and improved understanding of aquifer extent, aquifer properties and groundwater processes are required to adequately quantify the flow of groundwater in the region.
