Methods

Summary

To probabilistically simulate dewatering of the upper Permian coal measures in the Galilee subregion due to potential large coal mining operations identified in the coal resource development pathway (CRDP), an analytic element groundwater model (referred to as GW AEM) has been developed to estimate drawdown within the upper Permian coal measures and its propagation into the overlying Rewan Group, Clematis Group and Cenozoic cover.

The methods section provides a high-level overview of the conceptualisation, the modelling approach, the interaction with the surface water model and the uncertainty analysis in relation to the other companion products for this subregion and the submethodologies.
