Hydrogeological Landscapes (HGL) were developed to help local land managers understand landscape functions, assess hazards, and prioritise management actions. The 25 HGL units have been mapped based upon functional differences in geology, soils, slope, regolith thickness, and climate.
Descriptions of HGLs provide insights into the quality and distribution of water on the surface of the landscape and in the shallow subsurface. Each HGL contains a unique set of management issues requiring locally tailored management solutions in relation to issues such as dryland salinity, land degradation and wetland climate vulnerability.
For each HGL there is a ‘salinity report’ and a ‘soil and land degradation report’ that details local landscape functions, hazards, and management opportunities.
