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.
Standard Hydrologic Response Variables (HRVs) are the hydrological characteristics of the system that are important for studying the impact of streamflow on the ecological variables which can potentially change due to coal resource development. These data refer to the standard HRVs for the Namoi subregion for the 54 simulation nodes. The nine standard HRVs were computed under CRDP and Baseline conditions, respectively and the ACRD is the difference between the Baseline and CRDP.
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.
