On 14th March 1989 an extreme rainfall event caused record historical floodings in Lake Torrens and in the Pirie-Torrens corridor. The results of a joint Flinders University/Army expedition to monitor these events in which the water level and major ion content of the floodwaters in Lake Torrens were measured over the duration of the flood (March-December 1989), and the volume flow and major ion content of the flood in the Pirie-Torrens corridor which discharged into Spencer Gulf at Port Augusta and peaked on 17th March 1989 were recorded. The bathymetry of Lake Torrens was also determined from hydrological and existing dry land surveys, and subsequently compared with transects obtained from ..View full abstract
Support from the Flinders University Research Budget and the Centre for Research into Groundwater Processes, through emergency research funding without which the Lake Torrens expedition would not have been possible, is gratefully acknowledged. The Engineering & Water Supply Department, South Australia is also thanked for the loan of the two water level recorders, and it is a great pleasure to acknowledge the participation of the Army personnel from the South Australian establishment with whom a great working relationship was established which included the provision of the second boat used on the expedition. Several students also participated in the sampling programme, including Scott Chambers and Rosemary Byron-Scott, whose efforts were important in fulfilling the goals of the expedition. Helpful comments by two Reviewers are also gratefully acknowledged.
