The Impact of Groundwater Use on Australia

Product Information

The Impact of Groundwater Use on Australia's Rivers is the outcome of a year-long Land & Water Australia Senior Research Fellowship by Dr Richard Evans.

This report presents the technical understanding of the effects of groundwater pumping on stream flow in Australia, identifies associated technical challengers, and then develops management approaches to address the issue.

The relationship between groundwater pumping and stream flow is complex, with a range of time lags depending on local and regional factors. Between the start of pumping and the impact on the stream, the lag can be days, years or centuries.

The technical and management challengers to address the impact of groundwater pumping on stream flow are significant and a major effort by all water managers and users is required to address these challengers.
