How salinity has changed
Climate note, 1, IOCI (Indian Ocean Climate Initiative), 1st
2005
Abstract
Dryland salinity is driven by excess water in the landscape resulting from clearing of perennial vegetation. The decrease in winter rainfall and virtual absence of ‘wet winters’ has caused a slowing in the process of salinisation, and in some cases groundwater levels have fallen. Deeper bores are continuing to rise while shallow (< 8m) groundwaters have flattened. In the north-eastern
Wheatbelt, the occurrence of summer storms has created an erratic response.
Stream salinities in many streams have continued to increase because of reduced fresh runoff which, in wet years, dilutes the saline groundwater discharge. However, in catchments where groundwater levels no longer intersect the valleys because of falling levels, runoff has freshened.
