Abstract

Applying an artificial monolayer to a large water storage offers the most economic and environmentally benign
option for reducing evaporative loss. In July this year, the Urban Water Security Research Alliance commenced a
project to evaluate the sensitivity of scintillation and eddy covariance technologies in monitoring evaporative loss.
Seasonal changes in water quality and the limnology of surface and subsurface water samples in the absence of an
applied artificial monolayer will also be documented. Provided the instrumentation is sufficiently sensitive, the
project will also evaluate the effectiveness of a selected artificial monolayer in reducing evaporative loss, and its
ecological impact. Recent studies on South East Queensland (SEQ) water storages have established the existence of
natural microlayers, which also affect the properties of the air-water interface. If the ecological impact of an
artificial monolayer is equivalent to pre-existing microlayers, but more effective in reducing evaporation, the
technology may be appropriate for use on urban water storages.
