Updated description of Hydrogeological Landscapes of New South Wales and the Australian Capital Territory from
Hydrogeological Landscape (HGL) boundaries and descriptions have been derived for a number of project areas across NSW. The HGL concept provides a structure for the understanding of how salinity manifests itself in the landscape and how differences in salinity are expressed across the landscape. A HGL spatially defines areas of similar salt stores and pathways for salt mobilisation. The process of HGL determination relies on the integration of a number of factors: geology, soils, slope, regolith depth, and climate; an understanding of the differences in salinity development; and the impacts (land salinity/salt load/water electrical conductivity) in landscapes. Information sources such as soil maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard descriptions for each HGL unit. Derivative maps showing _overall salinity hazard_ and individual hazard due to salinity expressed as _land salinity, salt export (load)_ and _stream EC_ are available for most mapped areas, and are also viewable as custom layers in [eSPADE](http://www.environment.nsw.gov.au/espade2webapp). Overall salinity hazard uses a five class system (very low, low, moderate, high, very high). This helps the user identify and prioritise where salinity management actions may need to be targeted. Hazard due to salt land, salt export and stream EC uses a three class system (low, moderate, high). Knowing which of these are of greater significance in a HGL unit helps the user decide on the types of management actions that may be applied. __Data and reports are publicly available for the following HGL study areas:__ * Braidwood 1:100 000 Hydrogeological Landscapes: June 2010 (First Edition) _http://datasets.seed.nsw.gov.au/dataset/braidwood-1-100-000-hydrogeological-landscapes-june-2010-first-edition3dd02_ * Capertee-Lithgow Valleys Hydrogeological Landscapes: June 2010 (First Edition) _http://datasets.seed.nsw.gov.au/dataset/capertee-lithgow-valleys-hydrogeological-landscapes-june-2010-first-edition85e31_ * Goulburn Hydrogeological Landscapes: June 2011 (First Edition) _http://datasets.seed.nsw.gov.au/dataset/goulburn-hydrogeological-landscapes-june-2011-first-edition43e5f_ * Hydrogeological Landscapes for the Central West Catchment Management Authority Western Study Area: May 2013 (Second Edition) _http://datasets.seed.nsw.gov.au/dataset/hydrogeological-landscapes-for-the-central-west-catchment-management-authority-western-study-ar89be3_ * Hydrogeological Landscapes for the Eastern Murray Catchment: May 2015 (Second Edition) _http://datasets.seed.nsw.gov.au/dataset/hydrogeological-landscapes-for-the-eastern-murray-catchment-may-2015-second-edition46f7b_ * Sydney Metropolitan Western Study Area Hydrogeological Landscapes: March 2011 (First Edition) _http://datasets.seed.nsw.gov.au/dataset/sydney-metropolitan-western-study-area-hydrogeological-landscapes-march-2011-first-edition6fe4a_ * Western Sydney Hydrogeological Landscapes: May 2011 (First Edition) _http://datasets.seed.nsw.gov.au/dataset/western-sydney-hydrogeological-landscapes-may-2011-first-editionf20fe_ Spatial resolution varies between 1:50 000 and 1:250 000, depending on the resolution of the source data used to define the HGL boundaries.
