MBC Groundwater model

## **Abstract** 

The 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.



This data set comprises the  inputs, parameters and outputs of the OGIA groundwater models as used for BA groundwater modelling reported in the product 2.6.2 of Maranoa-Balonne-Condamine subregion. Only one input file (MODFLOW drain package input file) was modified for the BA specific model runs. This input file is provided within the folder named NIC_MBC_Model_Input_files. All other model inputs are the same as is used in the OGIA model runs for Underground water Impact Report 2012. These inputs may be requested from Office of Groundwater Impact Assessment and is not published in the BA repository as per the agreement with OGIA.

The OGIA drain package has been modified to include the boundary conditions caused by 7 mines in the MBC subregion. For this  a python script was written. The script reads the original drain package file (ASCII file) of OGIA model and then write additional drain cells to the file at the locations of the 7 mines - Commodore, newAcland stage 2, Wilkie Creek, Kogan Creek, Cameby Downs, New Acland stage 3 and The Range. The script reads the locations of these mines from input files - .dat  (to the script) with names similar to the mine names. The locations of the mines are specified as rows and columns of the model grid in these input files. These files also have the elevations of the drain cells (bottom/centre of the cells in the Walloon Coal Measures in which the coal mine pit is present). The location and elevation data were obtained from OGIA  and is registered as a separate data set. 

Two copies of the  python script are present in the folder corresponding to the baseline and CRDP drain packages.

## **Dataset History** 

All the model input data files were obtained from OGIA with the condition that these will not be published. The drain package input file and all output files were generated by CSIRO Land and Water by using CSIRO generated scripts and by running the model using these inputs. The drain package has inputs from the original OGIA model drain pakcage and additional data obtained from OGIA and coal mine footprint data. 



The coal mine footprint data sets is registered as a separate data set. The OGIA model is not registered as a separate source data set as it is not publishable as per the agreement.
