Gloucester River Types v01


This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

For the purposes of identifying the relevance of generic flow response models the streams were broken into five broad groups of flow regimes; the two mentioned earlier "permanent" and "ephemeral" regimes, and three further groups, "perennial and lowly intermittent", "intermittent" and "highly intermittent". Perennial being streams that typically flow all year round, but during drought will cease to flow during the dryer parts of the year. Lowly intermittent being streams where they can flow all year round but they typically have a seasonal cease to flow period. Intermittent being stream where they always cease to flow during the dry seasons of the year. And highly intermittent where the streams are virtually ephemeral but have extended tails to the events.

The five flow regime groupings are estimated from Ecohydrology classification work published by Land and Water Australia (Pusey et al. 2009). Two studies carried out as part of the "Ecohydrology regionalisation of Australia" project where used to estimates where the different flow regimes occur. The study, "Ecohydrology Classification of Australia's Flow Regimes" identified 12 flow regime classes, which did not only capture the frequency or intermittence of flow, but also the seasonality of specific flows (eg "stable winter baseflow", or "unpredictable summer highly intermittent" class). The study was based on measured streamflow sequences for a select number of gauging station where the flows are essentially natural, and while it considered techniques for predicting the 12 flow classes in points other than the selected sites a spatial layer of flow regime classes was not produced.

Dataset History

A spatial layer is derived from an Ecohydrology classification product, which is used to identify river hydrology classification base of the degree on intermittency flow of the rivers (see section 1.3.2 How Ecohydrology Classification is used). The riverine features are identified using the River Style® mapping (see section 1.3.3 How River Styles® is used).
