This is the master metadata record for the Victorian Aquifer Framework (VAF) 3D Surfaces dataset. For information on each aquifer surface, please refer to the separate metadata record. DEPI originally engaged GHD to develop seamless 3D aquifer surfaces for the Victorian Aquifer Framework (VAF). The seamless mapping of aquifers across the state provides the fundamental framework for groundwater resource management, underpins development of a revised management structure for Victoria (the Secure Allocation Future Entitlement project funded by the National Water Commission) and contributes to the data needs of the Bureau of Meteorology National Groundwater Information System (NGIS). The original dataset was produced by GHD in 2012 using (in part) data provided by Southern Rural Water Corporation and Goulburn-Murray Water Corporation. It has been subsequently amended by Hocking et al and SKM in 2013.

This dataset relates to the Victorian Aquifer Framework (VAF) 3D Surface for the Upper Tertiary Quaternary Aquitard. It represents the mapped extent of the aquitard. Please refer to the master metadata record VAF 'Victorian Aquifer Framework (VAF) 3D Surfaces' for detailed information.

This dataset relates to the Victorian Aquifer Framework (VAF) 3D Surface for the Lower Mid Tertiary Aquifer. It represents the mapped extent of the aquifer. Please refer to the master metadata record VAF 'Victorian Aquifer Framework (VAF) 3D Surfaces' for detailed information.

Statewide data showing Upper House boundaries and names. These are the Legislative Council Electoral boundaries referred to as the Upper House Boundaries. These boundaries are the result of the 2012-2013 State Redivision conducted under requirements of the Electoral Boundaries Commission Act 1982. These boundaries will apply at the Victorian State Election in 2014.

This dataset provides bore controlled residual gravity bedrock depth. It contains the Victorian geological basement surface and the distribution of the basal aquifer derived using gravity data and controlled by all basement boreholes extracted from the Groundwater Management System (GMS) and Geological Exploration and Development Information System (GEDIS) databases. Depth is presented as depth below ground surface. This technique was applied state-wide to the Upland Valleys, Murray Basin and Western Volcanic Plains. More reliable seismic and borehole data was used to map bedrock in the Gippsland and Otway Basin. The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.

This dataset comprises all basement boreholes reaching bedrock passing through basalt covered areas used for bore control of Free Air (FA) Gravity data. These boreholes have been used to give better control for interpolating to FA gravity data. The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.
