Salinity

Salinity refers to the movement and concentration of salt, in landscapes. Both soil and natural waters can become saline. Hence, salinity can be described as either soil salinity or water salinity.

Throughout Australia, there are large areas of naturally saline soils. Australia's arid climate and internal drainage system have produced a huge number and great variety of salt lakes. These lakes provide a history of salt in the landscape.

A number of our main rivers drain to internal lakes such as Lake Eyre in South Australia, where over time salts have been concentrated. These naturally saline lakes are called salinas. Areas such as these are regarded as Primary Salinity.
