System understanding phaseThe upsurge of limnological and water quality research from about 1970 resulted largely from a major increase in Federal Government funding. Research moved towards providing a basic understanding of the physical, chemical and biological processes controlling Australian aquatic systems rather than the mere collection of descriptive data.This developing interest in understanding ecosystems has been accelerated by a change in attitude by management agencies around Australia, which are now endeavouring to ensure that healthy ecosystems are maintained wherever possible in the nation's streams, lakes and reservoirs. Valuable work has also been done on the transportation and effects of heavy metals and nutrients in streams; the life histories of aquatic biota; and the usefulness of macro-vertebrates as biological indicators of water quality changes. Research has also been conducted into the water quality effects of land use activities such as forestry operations and broad-scale clearing. The stratification of water in reservoirs, which is important in determining water quality and in reservoir operation, has also been studied intensively since 1960.
