HUN Groundwater modelling mesh v01

Abstract

The dataset was derived by the Bioregional Assessment Programme without the use of source datasets. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

Finite element mesh for the groundwater model of the BA Hunter subregion. A regional-scale numerical groundwater model was built using the Multiphysics Object-Oriented Simulation Environment (MOOSE) modelling platform to evaluate the hydrological changes due to additional coal resource development on groundwater resources in the Hunter subregion. MOOSE uses the finite-element technique and the size in plan view was chosen to be 500 m in the vicinity of the mines, and up to 15 km elsewhere. Triangular elements are used. The finer mesh clearly identifies the areas of mining within the Hunter subregion. There is a higher density of elements along the river network. The mesh was created using python VTK libraries (see www.vtk.org) and converted to shapefile format for map display purposes. Also included in the dataset are shapefiles for the Mt Arthur, Tasman and Whybrow mines.
