dataset: IEC2021_SCORES

The IEC is made up of five subindices - Physical Form, Hydrology, Water Quality, Flora, and Fish. The overall score for each estuary is based on individual scores for the five sub-indices. Sub-indices are made up of one or more measures that, in turn, are underpinned by one or more metrics that provide information on threats or condition (DELWP 2021). Assigning each IEC metric to represent measures of either threat or condition aids interpretation of results and conceptual understanding of observed estuary condition to guide management options.
