Braidwood 1:100 000 Hydrogeological Landscapes: June 2010 (First Edition)

The Hydrogeological Landscape (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 soils maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard templates for each HGL.

The focus of this package is the Braidwood 1:100 000 map sheet area. It comprises five volumes - Volume 1: project background, regional setting, methodologies, interpretations, conclusions, glossary and references; Volume 2: HGL templates, and information associated with the use of the HGL templates; Volume 3: maps and digital spatial data developed for the project, including derivative maps to assist in land management decision making; Volume 4: background information relevant to land management for salinity in the Braidwood area. This includes information on salinity management from the perspectives of land use design, scales and types of management, landscape function, management strategies, actions and outcomes, as well as land use to be avoided; and Volume 5: findings and interpretations for a soil EC case study in the Windellama area. The soil laboratory measurements, electromagnetic survey and soil characterisations undertaken for the case study serve as a cross check to the information collected as part of the wider Braidwood HGL project.

Spatial resolution for this product is 1:100 000.
