About the guidelines
The purpose of this document is to outline decision rules that can be used to create unique national site codes for AusRivAS test and reference sites.
These rules are derived from a site coding system originally used in the Australian Capital Territory and surrounding region by Environment ACT and the Cooperative Research Centre for Freshwater Ecology [Nichols, Sloane, Coysh, Williams, and Norris 2000; Keen 2001]. They are also similar to a national site coding system developed by Waterwatch Australia [Waterwatch Australia 2002:68]. These rules are designed to facilitate the coding of river health assessment sites, particularly across jurisdictions at local, region, state, and national scales. They are designed to be compatible with the current regional and state-wide AusRivAS models and existing AusRivAS software. This site coding system provides a nationally consistent framework and allows AusRivAS sites to be identified using a unique alpha-numeric code that is simple, easy to understand, and consistent across varying jurisdictions, government agencies, and private sector organisations. The code also contains location "clues" that provide an approximate spatial reference for the site.
These decision rules are not meant to replace existing site coding techniques used by individual state and territory agencies for the Monitoring River Health Initiative and other purposes (although they could be used for this purpose). This site coding system is, however, recommended for all new AusRivAS sites.
