HUN AWRA-R nested calibration catchments v01

Abstract

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.

The dataset contains individual nested catchment shapefiles, a merged version of all catchments a geodatabase of those catchment shapefiles,a point shapefile containing the pour points used to delineate the catchments and an excel spreadsheet with areas of catchments and the percentage of each catchment covered by mine footprints for three scenarios (Baseline, CRDP and ACRD). These include nested catchments for the 65 surface water modelling simulation nodes in the Hunter subregion. These data are inputs to the surface water model for the Hunter.

Dataset History

The total upstream catchment for each simulation node was generated in ArcGIS -> Spatial Analyst -> Hydrology -> Watershed tool to create a shapefile of nested catchment polygons. The source inputs were used as pour point and flow direction parameters respectively. Pour points were snapped to the nearest point on a flowline.
