This dataset contains the Central West CMA HGLs that were not included in the Hydrogeological Landscapes of the Central West Local Land Services Region: Nov 2020 dataset. The CMA boundary was catchment-based, whereas the new LLS boundary is cadastre-based. The original CW CMA HGL assessments were undertaken between 2008 and 2012. 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 old Central West CMA catchment area that falls outside the new CW LLS region. The data package comprises the relevant HGL unit descriptions; digital spatial data; and legacy documents relating to the original CW CMA HGL assessments. Spatial resolution for this product is 1:250 000.
