The Murray Darling Basin Authority’s Sustainable Rivers Audit (SRA) program has developed a novel method for gathering and making sense of environmental and ecological data. Data gathered at a large number of sites according to agreed protocols are normalised to produce “metrics”, which compare observed values to estimated values under reference conditions appropriate to each variable. Metrics from different locations are spatially aggregated as required, grouped into ecological themes, and integrated by expert systems to produce condition indicators. The condition indicators for each theme are then integrated into an overall condition index, used to describe the state of river ecosystem health. This is used to communicate audit findings to regulatory authorities, and the public.
This paper describes the SRA data processing method, focusing on the role of expert systems. Key points are how the development of expert systems is facilitated by the use of metrics; by the way in which environmental specialists define what each integration exercise must do; and by the choice of membership functions to simplify defuzzification using the centroid method. The paper concludes by outlining work to apply the SRA principles
