Dataset: Gippsland Project boundary



The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.

This dataset is a shapefile of the project boundary for the Gippsland Bioregional Assessment.

Dataset History

The Gippsland Bioregional Assessment project boundary dataset was created by the Department of Environment and Primary Industry Victoria based on the following description.

Northern boundary: Victorian surface geology is used to identify the northern bounds of the surficial aquifers of the Haunted Hills Gravel and the Sale Group which overlie and conceal the coal bearing formations of the Gippsland Basin (differentiation of Tertiary-Recent geology from older geology along the proposed bioregion boundary). Topographic elevation along this northern boundary rapidly increases, with subsequent changes in hydraulic gradient and likely significant reductions in flow path lengths. The northern boundary delineates the transition from local scale groundwater flow systems (to the north of this boundary) and intermediate to regional scale flow systems (south of this boundary).

Western boundary: is a surface water and groundwater flow divide derived from the 250K Topographic dataset. Surface water on the western side of this boundary drains towards Western Port which appears to have little resource potential or exploration interest. Based on this scientific rationale and conceptualisation, the proposed boundary adheres to the conceptual/numerical groundwater model boundaries.

Southern/coastal boundary: clips the southern boundary to the 250K coastline as the Bioregional Assessments are investigating impacts from onshore Coal and CSG development. The WSS/BA model boundary extends offshore to account for petroleum industry abstractions offshore. It is important to note, the proposed bioregion boundary explicitly includes the Gippsland Lakes and is clipped to the national 1.25M national topography coastline.

Eastern boundary: has a similar rationale as the northern boundary, prospectivity for Coal/CSG development geologically diminishes further east of the Gippsland lakes.
