Back to Salinity Management
This study presents the distribution and characteristics of Groundwater Flow Systems (GFS) causing salinity in the West Gippsland region. As part of developing this document, a workshop involving key technical, agency and community representatives was held on 24-25 February 2005. A total of 12 Groundwater Flow Systems were defined for the West Gippsland region using a combination of information on geology, hydrogeology, soils, slope and local knowledge.
