Catchment condition index

A composite index was used in the overall assessment of catchment condition in Australia, during the National Land and Water Resources Audit1. The index was based on 14 indicators which were used to form three sub-indexes:

Coastal issues arising from catchment degradation

Coastal waterways with highly disturbed catchments may have to contend with the following problems:

 

Existing information and data

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 2. 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 1.
