The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets provided by the Bureau of Meteorology. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.
This dataset includes a shapefile containing the mean annual runoff, using the 'Budyko-framework' implementation of Choudhury, for NSW.
The mean annual runoff dataset was created as per the Donohue et al (2010) paper. The data represent the runoff expected from the steady-state 'Budyko curve' long-term mean annual water-energy limit approach using BAWAP precipitation and the Penman potential ET described in the source dataset.
