Abstract: Areas of catchments that drain directly to Victorian estuaries - i.e. not via major freshwater tributaries. The layer was derived by Deakin University as part of the project: "Linking catchments to the sea: Understanding how human activities impact on Victorian estuaries" funded by the National Heritage Trust and the Department of Sustainability and Environment.

Purpose: Areas of catchments that drain to directly to Victorian estuaries (rather than via main tributaries), excluding the Gippsland Lakes basin. It complements the Fluv_catchments layer that comprises areas of catchments draining to estuaries via fresh water tributaries. The ESTUARIES layer is an updated version of one that included estuaries and their upstream limits for catchment delineation. In this layer, attributes relating to population, outcropping geology, land use, geomorphology and rainfall are associated with each catchment polygon. In order to assess the relationships between catchment-based activities and estuary condition attributes from this layer were analysed as part of the Deakin University project "Linking catchments to the sea: Understanding how human activities impact on Victorian estuaries". Methods and results from this project are reported in Barton, J.L., Pope, A.J., Quinn, G.P. and Sherwood, J.E. (2008) Identifying threats to the ecological condition of Victorian estuaries (Department of Sustainability and Environment Technical Report, ISBN 978-1-74208-745-0 (online)).

Positional Accuracy: Polygons were created based on modelling of data from multiple sources as described above. The majority of catchment boundaries follow Vicmap 20m DEM cell boundaries. Metadata for the DEM states that it is suitable for use at a 1:25,000 scale. Where coarser DEMs and watercourse were used, there is less positional accuracy of boundaries.
Atribute Accuracy: Attributes for catchment polygons have been derived from a range of sources with differing collection dates and scales. While valid for broad scale comparisons across multiple systems, the accuracy of attributes may not be suitable for other applications. Refer to metadata of source layers for further details.
Logical Consistency: NA
Data Source: Data Set Source: Mean population density estimated from census collection districts (Australian Bureau of Statistics digital boundaries and data) for 2001 and 2006 censuses. Total catchment population derived from mean density and total area. Geological classes were derived from GEOL250 for Victoria and the 'Surface geology of Australia 1:1,000,000 scale, New South Wales' layer from Geosciences Australia Landuse was derived from several regional layers with currencies between 1997 and 2003: Gippsland Land Use 1:25000; Land Use Classification of North Central CMA; Land use of South-West Victoria - Port Phillip Region (Zone 55); Land use of South-West Victoria - Glenelg-Hopkins & Corangamite Region (Zone 54); Land use of Mid-Goulburn-Broken Catchment; 2003 South Australia State Land Use; and, for areas not covered by the above: 2001/02 Land Use of Australia, Version 3. Physical aspects of catchments were derived from Vicmap 20m resolution DEM. Annual rainfall derived from 0.025 degree grid of Mean Annual rainfall Data (Base Climatological Data Sets) from the Bureau of Meteorology (1961-1990).
