Summary
ABSTRACT The uncertainty aspects of the process of floods of Lake Eyre are examined. The available records of floods cover the time span of 40 years only. As longer time series of precipitation records are available, one has extended the observed series of inflows to Lake Eyre with the help of a rainfall–runoff model. Further reconstruction of the inflow series has been achieved with the help of proxy data of coral fluorescence intensity. However the limitations of these extensions and reconstructions of inflows are severe. The process of inflows to Lake Eyre could be considered one of the most convincing manifestations of hydrological uncertainty.
LAKE EYRE AND ITS BASIN
Lake Eyre, a large depression in arid Australia, rarely filled with water, attracts the interest of limnologists, hydrologists, geomorphologists and ecologists all over the world. The process of inflows to Lake Eyre has been recently studied by Kotwicki (1986). The following general information draws from the data assembled there.
The Lake Eyre basin (Fig. 1) spreads over 1.14 million km2 of arid central Australia. Almost half of the basin area receives as little rainfall as 150 mm per year or less. The higher rainfalls of the order of 400 mm per year occur in the northern and eastern margins of the basin, influenced by the southern edges of the summer monsoon.
