Hydrogeological landscapes (HGL) have been developed to characterise and manage the quality and distribution of water on the surface and in the shallow sub-surface of the landscape. The HGL unit descriptions provide a framework which spatially defines salinity management areas and recommends how best to manage and prioritise these landscapes.
In this project undertaken for the Hawkesbury-Nepean Catchment Management Authority, 24 different HGLs have been defined, each with unique salinity situations (salinity management areas) which require tailored management solutions involving specific management actions.
