The causes of increasing salinity

Bettanay, E. (1979) The causes of increasing salinity. The West Australian, 10 April 1979. p. 60 [Publication] [Special Collections]


Article discusses the history and geography of the cause of increasing salinity, with the focus on Western Australia.
The landscape has been eroded to a generally low relief, undisturbed by mountains or the action of glaciers.
The watershed in the south of Western Australia, which marks the limit of drainage to the Southern and Indian Oceans, is a broad upland no higher than 600 metres.
The watershed passes through dry areas with high evaporation which produces no permanent rivers inland.
Valleys are often blocked with debris such as sand, silt and gypsum, where streams when running, cannot remove.
Understanding the land forms of Western Australia helps with the understanding of the cause of increasing salinity.
Note included, Eric Bettanay is a senior principal scientist with the land resources management division of CSIRO in Perth.
A version of this article first appeared in the Journal of Agriculture.

This article contains two images, one of a diagram showing how salinity builds up in areas , and one photograph of Unknown testing water at the Gwelup plant in Perth.
