Groundwater recharge from surface water features, particularly rivers, is an important process on the coastal plains, but could not be quantified due to insufficient data and lack of a suitable quantification approach.
the Mount Lofty Ranges, groundwater frequently contributes to the baseflow component of streamflow and recharges deeper aquifers (Harrington 2004). On the Adelaide plains, the streams are assumed to be predominantly losing water, although the volume of stream leakage to groundwater could not be quantified for the 2009–10 water accounting report.
