Groundwater Flow Systems of the Launceston Municipal Area

A NAP (National Action Plan) funded project headed by the NRM North and NRM South to delineate the major Groundwater Flow Systems (GFS) for councils (14 in total) in the NAP part of Tasmania. The digital map forms part of the larger project pertaining to 'Salinity Hazard and Critical Asset Assessment' assigned to each council of the NAP region in Tasmania. Consequently, the Launceston municipality make up one of these councils and a separate report with accompanying paper maps make up this partof the project. The digital map comprises polygons mapped at a variety of scales in different parts of the municipal area (1:25,000, 1:50,000 & 1:63,360) and geo‐referenced to the GDA94 datum. Each polygon is attributed with the relevant GFS as well as Salt store potential which equates to potential salinity hazard. Conceptual diagrams with detailed descriptions of the GFS's are also available and appear in the accompanying report.
