Abstract

A prototype decision support system has been developed to assess the environmental outcomes of proposed flow regimes for the regulated, lowland floodplain rivers of the Murray-Darling Basin in Australia. The DSS assesses the environmental outcomes of proposed flow regimes primarily by providing integrated assessments of river health at different spatial scales based on the outputs from riverine habitat condition and riverine nuisance species models. These models rely on data from river hydrology simulation models — both within and external to the DSS. The current version of the software includes three models of riverine habitat condition: native fish, floodplain vegetation, and waterbird breeding. The only riverine nuisance species model currently included is a model to predict the severity of blue-green algal blooms. In this paper a brief description of the DSS framework and the nature of the underlying models is provided. The paper focuses on describing the methods used to integrate the individual model outputs into overall river health assessments.
