Input climate data: daily time series of maximum temperature, minimum temperature, incoming solar radiation and precipitation from 1981 to 2012 at 0.05 x 0.05 degrees (~5 x 5 km) grid cells from the gridded data generated by the Bioregional Assessment Programme (Dataset 1).

Streamflow: daily streamflow data from 16 unregulated catchments collated by the Bioregional Assessment Programme (Dataset 2) were used for model calibration (Figure 8). Out of the 16, four contribute to the Gloucester or Karuah river basins, including the Barrington River at Forbesdale (calibration gauge 208006), Gloucester River at Gloucester (208020), Mammy Johnsons River at Pikes Crossing (209002) and Karuah River at Dam site (209018). Of the remaining catchments, five are in the Manning river basin, six are in the Hunter river basin and one is in the Wallis Lake river basin.

Criteria for selecting the calibration catchments include that they:

  • have long-term measurements (>20 years from 1980)
  • are not impacted by coal mining or coal seam gas extraction
  • have no significant flow regulation (e.g. dams)
  • are not nested
  • are close to the Gloucester subregion and have similar catchment sizes and climate regimes.

Boundaries for the 16 catchments were delineated using the Geofabric (Bioregional Assessment Programme, Dataset 1).
