The dataset was derived by the Bioregional Assessment Programme from multiple datasets. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.
Hydrological Response Variables (HRVs) are the hydrological characteristics of the system that potentially change due to coal resource development. These data refer to the HRVs related to the AWRA L and AWRA R models for the Hunter subregion for the 65 simulation nodes (63 within Hunter basin and 2 within Macquarie-Tuggerah Lake basin). The nine hydrological response variables (AF, P99, FD, IQR, ZFD, P01, LFD, LFS, LLFS) were computed by the AWRA L and AWRA R models under CRDP and baseline conditions, respectively and the ACRD is the difference between the Baseline and CRDP.
Abbreviation meaning
AF - the annual streamflow volume (GL/year)
P01 - the daily streamflow rate at the first percentile (ML/day)
P01 - the daily streamflow rate at the first percentile (ML/day)
IQR - the inter-quartile range in daily streamflow (ML/day). That is, the difference between the daily streamflow rate at the 75th percentile and at the 25th percentile.
LFD - the number of low streamflow days per year. The threshold for low streamflow days is the 10th percentile from the simulated 90-year period (2013 to 2102)
LFS - the number of low streamflow spells per year (perennial streams only). A spell is defined as a period of contiguous days of streamflow below the 10th percentile threshold
LLFS - the length (days) of the longest low streamflow spell each year
P99 - the daily streamflow rate at the 99th percentile (ML/day)
FD - flood days, the number of days with streamflow greater than the 90th percentile from the simulated 90-year period (2013 to 2102)
ZFD - Zero flow days
This is the dataset used for the Hunter 2.6.1 product to evaluate additional coal mine and coal resource development impacts on hydrological response variables at 65 simulation nodes.
The HUN AWRA model outputs were used to determine the impacts on the HRVs to produce these data. The nine HRVs (AF, P99, FD, IQR, ZFD, P01, LFD, LFS, LLFS) were computed under CRDP and baseline conditions, respectively. The difference between CRDP and baseline is used for predicting ACRD impacts on hydrological response variables at 65 simulation nodes.
