This dataset supersedes much of the area covered by previous CW CMA and Western CW catchment HGL assessments. It is bounded by the Central West LLS regional boundary rather than the old CW CMA boundary. For CW CMA areas that fall outside the CW LLS boundary, please refer to the Residual Hydrogeological Landscapes of the Central West CMA Catchment: Nov 2020 dataset. 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 dataset is the Central West LLS region. It comprises introductory information on HGLs; HGL unit descriptions; digital maps and spatial data. Spatial resolution for this product is 1:250 000.
