Flow Regime: ecohydrological regionalisation of north Australia

What this map shows

Ecohydrological Regionalisation (flow regimes)

The information provided here is derived from TRaCK project 3.3 – Ecohydrological regionalisation for Australia (http://www.track.org.au/research/project/303). This project provided a continent wide classification of Australia’s natural flow regimes based on 830 Australian streams gauges.

Summary information for each gauge can be accessed by clicking on the gauge markers on the map. Included in this information is the gauge name and number and the ecohydrological class to which it belongs plus a selected subset of the hydrometric data for that gauge.

Full access to all hydrometric information for any gauge can be accessed via the excel page.

Flow Regime Classification

The flow regimes present in north Australia are briefly explained using composite hydrographs (eg, below).

[Data download]

Note: All metrics within this data set that relate to magnitude (i.e. actual volume of water) have been standardized by dividing by mean annual daily flow. This ensures comparison between locations are independent of stream size.

If the user needs volumetric information, then the appropriate calculations need to be undertaken (i.e. metric needs to be multiplied by mean annual daily runoff x catchment area).

The user is urged to review the Codes in the data file to properly understand how each metric was calculated.
