The North Esk Hydrogeological Landscape (HGL) is characterised by low plains and terrace landforms adjacent to the North Esk River. This HGL is located in south and west Launceston and traces the path of the North Esk River. This is an area of moderate rainfall (680mm). It forms a low-lying area that is strongly influenced by Quaternary to Recent processes of the North Esk River with increasing influence from the estuarine Tamar River toward the confluence in the north.
Typical lithologies for this HGL are Late Cenozoic terrace deposits and Quaternary to Recent poorly-consolidated clayey silt, silt, sand and some gravel. The landscape consists of alluvial channels, low plains and terrace landforms (typically <10m, but up to 20m), and associated marshes.View Report
