Namoi groundwater model input shapefiles

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThese shapefiles are used to create the maps in NAM2.6.2. They are mostly derived from the input files for the groundwater model. The shape files infclude:\n\n\n\nag_extraction: These are points that represent the location of groundwater bores used for agricultural extraction. \n\n\n\nboundaries: These are line shape files used for defining the location and extent of lateral boundary conditions of different stratigraphic layers of the groundwater model\n\n\n\ncoal extraction: These are polygon shape files providing the areal extent of the baseline and ACRD coal mines in the Namoi subregion that are including in the groundwater model.\n\n\n\ngrid: Polygon shape file representing the mesh of the groundwater model. It also include points that represent the midpoints of each model cell and the suset that represents the model nodes that outcrop.\n\n\n\nobs: Shape file of observation bores, the data from which is used for constraining the groundwater model.\n\n\n\nRiver: Set of shape files containing the AWRA catchments, AWRA-R nodes, network of rivers and creeks classified into important reaches and non important reaches based on the distance form the CRDP areas, extent of flood and irrigation recharge\n\n## **Purpose** \n\nThe purpose of this dataset is to create pretty pictures. The actual model inputs files are archived separately.\n\n\n\nThese shapefiles are used along with the software ALGOMESH to generate inputs for the models including model initial and boundary conditions.\n\nThease are also used to generate maps in the product 2.6.2\n\n## **Dataset History** \n\nSome of the components of this dataset are source data. These include the locations of groundwater and observation bores, river and creek network.\n\nOther components are derived:\n\n\n\nThe groundwater model mesh and model cell centres are generated in the ALGOMESH software and exported as shape file.\n\n\n\nThe coal mine extents are derived from digitized mine footprints.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) Namoi groundwater model input shapefiles.
