Topographic Drainage Divisions
and River Regions
Geofabric
Topographic Drainage Divisions and River Regions derived from the Australian Hydrological Geospatial Fabric
National Topographic Drainage Divisions and River Regions are currently derived from Geofabric version 2. Providing a set of surface water reporting units based on drainage-enforced digital elevation models, they are used to depict where water flows and drains across the landscape.
Topographic Drainage Divisions and River Regions updates boundaries based on current research, data and technology. It references previous work of the Australian Water Resources Management Committee as shown in Australia's River Basins 1997. The divisions and regions exist within the Geofabric's Hydrology Reporting Regions with data available for download.
