Alternative title(s)

South Creek HGL - 2020

Abstract

This dataset was developed to support the South Creek Stormwater Project (SCSP). Primarily a desktop study, existing Western Sydney HGLs covering the South Creek area have been reviewed and adjusted to reflect available soil mapping. LF7 landform modelling for the catchment has been used to define HGL management zones to which salinity hazard ratings are assigned. These ratings are at a landform element scale, an improvement on the original HGL ratings which were applied to the whole HGL unit.

For this dataset, additional information can be found in the relevant HGL unit descriptions provided in the original Western Sydney HGL data package.

Spatial resolution for this product is 1:50,000.

This is intended to be an interim product. A future update will incorporate more recent refinements to the soil landscape boundaries and provide basic descriptions for the updated HGL units in South Creek. It is also intended to add a small area of the Western Sydney Aerotropolis zone that falls outside the South Creek catchment.

The HGL concept provides a structure for understanding how differences in salinity are expressed across the landscape. A HGL spatially differentiates areas with similar salt stores and pathways for salt mobilisation. The process of delineating a HGL relies on the integration of a number of causative factors: geology, soils, slope, regolith thickness, and climate; an understanding of the different modes of salinity development; and the impacts of salinity within landscapes (land salinity, salt load and salt concentration in streams due to salt contributions from base flow and runoff). Information sources such as soil landscape maps, site characterisation, salinity occurrence maps, hydrogeological data, surface water and groundwater data are incorporated into standardised unit descriptions.

Hydrogeological Landscapes (HGL) and associated salinity impacts and hazards are available as a custom layer in eSPADE, which includes links to individual HGL unit descriptions.

Lineage

The hydrogeological landscape (HGL) mapping used the following base data for delineation of map units: Existing Western Sydney HGL mapping; Published 1:250 000 geological mapping data (polygon); Published 1:100 000 and 1:250 000 soil landscape data (polygon); Soil profile data from the DPE SALIS database (point); Digital Elevation Model (DEM) for South Creek catchment and derivative products taken from the 5 and 30 metre DEM.

DQ Topological Consistency

Effective date

2022-03-16

Explanation

All polygons in the coverage are topologically correct and all polygons have been attributed. Data has been visually checked at applicable scales.

DQ Absolute External Positional Accuracy

Effective date

2022-03-16

Explanation

The accuracy of the coverage varies across the mapping area as map polygon boundaries were derived from different sources. HGL boundaries derived from published and draft 1:100 000 scale mapping are generally accurate to 100 m. HGL boundaries derived from published 1:250 000 scale mapping are approximate and generally accurate to 250 m.

DQ Non Quantitative Attribute Correctness

Effective date

2022-03-16

Explanation

All polygons are labelled with a hydrogeological landscape unit tag, and attributed with information relevant to salinity management. Attributes were checked as part of routine GIS capture quality assurance procedures, including a visual check of polygon tags against field data.
