Groundwater Flow Systems Report (2005)
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.
