Regional patterns of salt lake morphology in the lower Yarra Yarra drainage system of Western Australia

The Morawa sub-division in the west of the region was morphologically different from the remainder of the lower lacustrine system in that it had a predominance of small, elliptical playas and lacked a major playa. It was postulated that lake segmentation processes have been enhanced in this part of the system through a combination of local climate variation, the near-parallel orientation of the thalweg of the drainage system axis relative to prevailing winds, with possible topographical relief and geological influences.
