A composite index was used in the overall assessment of catchment condition in Australia, during the National Land and Water Resources Audit . The index was based on 14 indicators which were used to form three sub-indexes:
Coastal waterways with highly disturbed catchments may have to contend with the following problems:
More information and maps showing the overall catchment condition index, the sub-indices and indicators can be found at the Catchment Condition Online Maps website . Appendix I (pp. 311-312) in Volume 2 of the Australian Catchment, River and Estuary Assessment, 2002 contains a map of Australia's River Basins and Drainage Divisions in which each river basin has been assigned a number. These catchment numbers can be matched to a large number of coastal waterways in pages 316-363 of the same document. The catchment condition index for a large number of river basins are available in Appendix B (pp 65-76) of the Assessment of Catchment Condition in Australia's Intensive Land Use Zone: A biophysical assessment at the national scale .
