Baseline Delta groundwater data for Gippsland scenarios

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

Baseline groundwater data within this geodatabase was generated by Craig Beverly in the Gippsland Regional Groundwater Model (Beverly et al, 2015).

It contains depth to groundwater in a number of scenarios based on year and the change in simulated depth to watertable predicted using the USGS MODFLOW-2005 finite difference groundwater model for one year relative to another year baseline conditions. These scenarios covered a greater area than the BAP and were reused in this Programme.

Purpose

The purpose of the modelling was to quantify the impacts of potential onshore gas projects. The design of the scenarios was to consider combinations of tight and shale gas and coal seam gas extractions within defined prospective development regions. ... The impacts of each predictive scenario were estimated based on a comparison with a defined baseline condition...

Importantly, it is considered that while the developed groundwater model cannot be used predictively to quantify the water balance or water levels at the regional scale under specific development scenarios, it is appropriate for comparison of different scenarios for volumetric changes to the water balance or water levels against a baseline condition.
