Braidwood 1:100 000 Hydrogeological Landscapes: June 2010 (First Edition) |
Alternative title(s) |
Braidwood Hydrogeological Landscapes (HGL) |
Abstract |
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. |

Lineage |
The hydrogeological landscape (HGL) mapping used the following base data for delineation of map units: Published and pre-publication 1:100 000 geological mapping data (polygon) - Braidwood 1:100 000 map sheet area; Published and pre-publication 1:100 000 and 1:250 000 soil landscape data (polygon); Soil profile data from the DECCW SALIS database (point); Digital Elevation Model (DEM) for Southern Rivers CMA and derivative products taken from the 25 metre DEM; Radioelement imagery derived from the Radiometric Map of Australia, 1st Edition, 2009, and; Field observations and assessment. The published, pre-publication and reconnaissance level mapping were combined and rationalised to create a complete hydrogeological landscape classification (map unit) coverage for the entire Braidwood 1:100 000 map sheet area. |

DQ Topological Consistency |
|
Effective date |
2010-07-01 |
Explanation |
All polygons in the coverage are topologically correct and all polygons have been attributed. Data has been visually checked at applicable scales. |
DQ Absolute External Positional Accuracy |
|
Effective date |
2010-07-01 |
Explanation |
The accuracy of the coverage varies across the mapping area as map polygon boundaries were derived from different sources. HGL boundaries derived from published and draft 1:100 000 scale mapping are generally accurate to 100 m. HGL boundaries derived from published 1:250 000 scale mapping are approximate and generally accurate to 250 m. |
DQ Non Quantitative Attribute Correctness |
|
Effective date |
2010-07-01 |
Explanation |
All polygons are labelled with a hydrogeological landscape unit tag, and attributed with information relevant to salinity management. Attributes were checked as part of routine GIS capture quality assurance procedures, including a visual check of polygon tags against field data. During the fieldwork phase, regular meetings were held to discuss and review methods, processes and consistency in landscape interpretation and documentation. |
