Extent of Study Area GIP

Abstract

The dataset was compiled by the Bioregional Assessment Programme from multiple sources referenced within the dataset and/or metadata. The processes undertaken to compile this dataset are described in the History field in this metadata statement.The Gippsland Basin Bioregional Assessment groundwater model uses this extent to derive its data sets and to plot the outputs from the model. The shapefile is used to cut any inputs that are on a larger scale and to fit them into the groundwater model. The extent includes both onshore and offshore Gippsland Basin extents to incorporate offshore oil and gas industry extractions and the influence of these on onshore aquifers. This extent is the same as that used in the Victorian Onshore Natural Gas Water Science Studies undertaken to determine the potential impact of future exploration and extraction of oil and gas (conventional and non-conventional) on water resources in the Gippsland Basin.

Purpose

This shapefile is used to cut and present other datasets to the groundwater model extent.

Dataset History

This shapefile delineates the extent of the groundwater model for the Gippsland Basin Bioregional Assessment and is based on the same extent used for the Victorian onshore natural gas water science studies undertaken in 2015. This study required the development of a groundwater model for the Gippsland Basin (both on and offshore) to investigate and understand the potential impacts of future onshore gas developments and to understand the possible impacts of a potential onshore natural gas industry on groundwater and surface waters within the Gippsland region. The groundwater model (Beverley et al., 2015) was constructed in MODFLOW-2005 and adopted a uniform spatial resolution of 400m with a spatial extent of 6,698,000 ha, of which 3,629,000 ha exists onshore and 3,069,000 ha offshore. This model is available online under the Victorian onshore natural gas website.
