How is salinity measured?

The different methods of measuring salinity are:

  • surface water salinity using a salinity or electrical conductivity meter
  • watertable depth and groundwater salinity using groundwater monitoring bores (test wells and piezometers)
  • soil salinity mapping using a salinity meter or electromagnetic induction instruments
  • discharge outbreak mapping using aerial photographs or remote sensing to provide a picture of the symptoms of salinity.

Salinity in a landscape is measured to help:

  • indicate how much salt is in the soil or water
  • build a picture of salinity in waterways and catchments
  • assess the effects of changes in land management
  • identify where saline groundwater is likely to come to the surface.
