Natural flow visualization in Lake Eyre, South Australia



Lake Eyre is maintained by the largest inland drainage system in Australia. Major floodings of the lake are rare occurrences. The largest historic flooding occurred in 1974, which gave an opportunity to make basic measurements of the lake bathymetry and hydrology [Bye, 1978; Bye and Will, 1985]. In January 1984, another major flooding occurred, and a preliminary aerial reconnaissance of the lake on March 27 and 28, 1984, laid bare a new facet of the fascinating character of the lake: that it can be regarded as a vast natural flow visualization tank.
