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.
