The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are 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.
Ecologic Hydrologic Response Variables (HRVs) are the hydrological characteristics of the system that are instrumental in maintaining and shaping ecological services and can potentially change due to coal resource development. These data refer to the ecologic HRVs for the Namoi subregion for the 54 simulation nodes. The nine ecologic HRVs were computed under CRDP and Baseline conditions, respectively and the ACRD is the difference between the Baseline and CRDP.
A full description of each of the variables are given in:
d2da0bc3-2eb8-408b-9d12-13f5c1d6d683 Namoi ecological Hydrological Response Variables (HRVs)
Selected ACRD future HRV normalized data from the source data, extracted and cross-tabulated in MS Access. Then exported as a table to be appended to the node features attribute table.
