Bathurst Urban Hydrogeological Landscapes: June 2011 (First Edition)

Alternative title(s)

Bathurst Urban HGLs

Abstract

The Hydrogeological Landscape (HGL) concept provides a structure for the understanding of how salinity manifests itself in the landscape and how differences in salinity are expressed across the landscape. A HGL spatially defines areas of similar salt stores and pathways for salt mobilisation. The process of HGL determination relies on the integration of a number of factors: geology, soils, slope, regolith depth, and climate; an understanding of the differences in salinity development; and the impacts (land salinity/salt load/water electrical conductivity) in landscapes. Information sources such as soils maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard templates for each HGL. The focus of this package is the Bathurst urban area managed by the Bathurst Regional Council (BRC). This metadata relates to the maps and digital spatial data developed for the project, including derivative maps to assist in land management decision making. This includes information on salinity management from the perspectives of land use design, scales and types of management, landscape function, management strategies, actions and outcomes, as well as land use to be avoided.

Spatial resolution for this product is 1:10 000.

Purpose

This data package was generated for the Bathurst Regional Council (BRC). It provides a framework to assist in the understanding of landscapes, the variability across the landscape, appropriate management activities and an understanding of salinity impacts in heritage areas. It will allow for more informed decisions leading to better planning and urban development strategic outcomes.

Lineage

The hydrogeological landscape (HGL) mapping used the following base data for delineation of map units: published 1:250 000 geological mapping data (polygon); published 1:250 000 soil landscape data (polygon); published 1:100 000 regolith-landform mapping data (polygon); hydrogeological landscape systems data for the Central West CMA area (polygon); Digital Elevation Model (DEM) for the Central West CMA area and derivative products taken from the 25 metre DEM; geophysical (radiometrics) imagery; and field observations and assessment. The published and reconnaissance level mapping were combined and rationalised to create a complete hydrogeological landscape classification (map unit) coverage for the entire Bathurst Urban Study Area.

Effective date

2011-07-01

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. Greater accuracy is achieved through field observations and assessment.

Effective date

2011-07-01

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. During the fieldwork phase, regular meetings were held to discuss and review methods, processes and consistency in landscape interpretation and documentation.
