Hydrologic Reference Stations
Station selection guidelines
The streamflow gauging stations contained in the Hydrologic Reference Stations allow identification of streamflow variability and trends, and are useful for providing long-term and seasonal prediction of water availability.
The station selection guidelines, developed by Sinclair Knight Merz (SKM 2010), outline the criteria for a streamflow gauging station to be added to the Hydrologic Reference Stations.
The Bureau applied these guidelines across all Australian streamflow gauging stations Turner et al. (2012), and as a result, selected the 222 stations currently contained in the Hydrologic Reference Stations. The Bureau intendeds to review the Hydrologic Reference Stations every one to two years and may add new stations that satisfy the station selection guidelines.
Applying the station selection guidelines is a four-staged process:
- Identify unregulated catchments with minimal land use change.
- Identify gauging stations with high quality streamflow observations and a long period of record (greater than 30 years).
- Ensure the distribution of streamflow reference stations is spatially representative of all hydro-climate regions in Australia.
- Consult with relevant agencies in each jurisdiction to review the application of the guidelines.
The aims and criteria of the station selection guidelines were then divided into four phases. These phases are detailed in the table below. For more information about the application of the guidelines please see Turner et al. (2012).
|Phase||Aim||Criteria applied to achieve aim|
|1||To collate a list of potential hydrologic reference stations||
|2||Undertake stakeholder consultation to identify and understand impacts in upstream catchments that may impact on the quality of the streamflow reference stations||
|3||Quantify land use changes and hydrological quality of streamflow series||
|4||To identify climate region||
