Evaporation data are summarised from separate lysimeter installations involving forest, crops and pastures along the 35°S parallel in south-eastern Australia. In each study, lysimeter representativeness was established from its response as evaporation rate or soil water change in comparison with corresponding values measured independently for external conditions. Specific objectives for obtaining evaporation data with each installation are described and achievements in meeting objectives are outlined. Distinctive features of each undertaking as by-products of the analysis of evaporation data are discussed.
