Hydrogeological Landscapes of the Capertee and Coxs River Valleys: August 2019 (Second Edition)

This dataset supersedes 'Capertee-Lithgow Valleys Hydrogeological Landscapes: June 2010 (First Edition)'. It consolidates the original four volumes into one report. Hydrogeological landscape (HGL) boundaries and descriptions have been reviewed and modified as necessary.

A reformatted version of the main report was added to the data package in January 2020.

The focus of this dataset is the Capertee and Coxs River Valleys in NSW. It contains digital spatial data developed to assist in land management decision making. The dataset contains hazard ratings for land salinity, stream salt load and stream EC as well as overall salinity hazard for each HGL unit. The associated report and descriptions provide information on salinity management for each HGL unit.

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.

Spatial resolution for this product is 1:100 000.

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.
