Namoi groundwater drawdown grids

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 dataset contains the grids of assessment units with the percentiles of drawdown for baseline, coal resource development pathway and additional coal resources development. Grids for every 5th percentile between the 5th and 95th percentile.

Dataset History

The results of drawdown from NAM_GW_Uncertainty_Analysis at the model nodes for baseline, crdp and acrd are interpolated to grids.

The custom made R script 'Rscripts/interpolateToGrid_i.R', which is executed on the high performance computers with the batch file interpolateNamoi.slurm. The script calculates the percentiles (every 5th between 5th and 95th) and interpolates them to the assessment units. The results are stored in ascii grid files Namoi_$maxtyp$$scen$_quantile$perc$.asc with $maxtyp$ tmax or dmax, $scen$ acrd, base and crdp and $perc$ the percentile.
