HUN DEM derived catchment boundaries v01

## **Abstract** \n\nThe 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. \n\n\n\nNested contributing catchments for selected stream gauges in the Hunter subregion. Generated from the Geoscience Austraila 9 second flow direction grid. Catchments exist as both a geodatabase grid and a shapefile version.\n\n## **Dataset History** \n\nSelected gauge locations were used as pour points to generate contributing catchment areas from the GA 9 second flow direction raster. The catchment delineation was achieved using the ArcGIS 10.1 Spatial Analyst WATERSHED tool from the Hydrology toolbox. Resultant watershed raster was also converted to a shapefile (no generalisation).\n\n## **Dataset Citation** \n\nCSIRO (XXXX) HUN DEM derived catchment boundaries v01.
