Murray-Darling Basin Sustainable Yields Modelling Catchments


CSIRO, through the Water for a Healthy Country National Research Flagship, was contracted by the National Water Commission to assess the current and future water availability in 18 regions across the Murray-Darling Basin (MDB) considering climate change and other risks to water resources. The 18 reporting regions identified for the project are the ... more

Boundaries Catchment Boundaries Boundaries Catchment Boundaries


These boundaries are compiled from available sources and selected according to their perceived authority and then by accuracy. The boundaries have gone through many revisions with the best data available at the time. Spatial and attribute accuracies are unknown given that is the status of many of the input datasets, however, it was assumed to be within the tolerance of the 5x5 km cells used for modelling in the MDBSY project. Sacramento catchments were generated from the 25m Digital Elevation Model (DEM) watersheds obtained from NSW Department of Natural Resources (DNR) (2007) as ESRI Shapefiles and then converted to an ArcGIS Coverage and cleaned. Subsequent catchments were merged keeping the boundaries of those previously processed. This was an iterative process to obtain catchments that matched the state river models, and incorporated the naming convention adopted in the MDBSY project for river system modelling. Given the known inconsistencies in datasets used, it is intended that this coverage forms the basis for deriving the boundaries again from a single, better quality DEM covering the whole MDB. The attribute 'rep_cat' (was 'reporting catchments' but subsequently renamed to 'reporting regions') is used to derive reporting regions by dissolving polygons on this attribute. NSW DNR Sacramento catchments from 25m DEM watersheds old DNR gauged (pre Pineena) catchments ca. 1995. NSW LIC 25m DEM and generated contours from Geoscience Australia 9'v2 DEM (and for some catchments 9’v3 was used) and generated contours dynamic set of Australia-wide gauges. 1v7 SKM Victorian gauged catchments added. The 'Fenner School of Environment and Society' at Australian National University, generated some specific gauges in the Upper Darling. Please note that the Snowy sub-catchments have been altered from those used in the Murray-Darling Basin Sustainable Yields project to reflect the operations of the Snowy Scheme. The sub-catchments have been matched to the outputs of the Snowy Model in terms of their respective inputs to the Murray and Murrumbidgee reporting regions. Fundamentally this is by the Snowy-Murray Development (diverts water to the Murray River) and Snowy-Tumut Development (diverts water to the Murrumbidgee River), in line with the catchment based sharing of inflows rules, as set out in the Snowy Water Licence. In the attribute table new polygons have been named Snowy Murray and Snowy Tumut catchments. References for these catchments have been coded to the Murray and Murrumbidgee reporting regions respectively. Credit: The Murray-Darling Basin Sustainable Yields project was undertaken by CSIRO under the Australian Government's Raising National Water Standards Program, administered by the National Water Commission. CSIRO acknowledges the contributions of datasets from ACTEW Corporation, Australian National University (Fenner School of Environment & Society), Department of Environment and Resource Management (Queensland), Department for Water (South Australia), Geoscience Australia, Department of Sustainability and Environment (Victoria), Department of Environment, Climate Change and Water (New South Wales) and Snowy Hydro Limited, which were used in the derivation of the catchment boundaries and reporting regions datasets.
