Flinders Ph.D. graduate Tom Anderson led a study of Scott Creek, a high rainfall area, that shows the combination of time and volume of water flow has resulted in salt regression through it being flushed from the water table.

He believes the methodology could have wide application across Australia – especially reading areas where streams and rivers have been affected by high salinity.
