Galilee Drawdown Rasters

## **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 rasters of the 5th, 50th and 95th percentile of drawdown in the model layers as well as grids of the probability of exceeding 0.2, 2 and 5 m drawdown as estimated with the GAL AEM model. The original rasters have been modified slightly so as to produce maps. These maps are an essential part of the visualisation of groundwater model results in Peeters et al. 2017). The process involved in creating these is described in the history.

## **Dataset History** 

The Galilee drawndown rasters were derived from GAL_quantile_interpolation_v2 (c7c4f7d0-ed25-475b-abcc-de7a1cbca3c3) using the ArcGIS platform for the purposes of creating maps.



The rasters were created by converting the original ascii grids to tiffs and then clipping the tiffs to the appropriate extents.



Both the Clematis and BCB rasters were clipped using datasets from the GAL_Model_Aquifer_Extents (5afbf7f1-1ee0-444b-9f77-dbad8d8de95b). The Clematis rasters were clipped using Clematis_warang_top_extent and the BCB rasters were clipped using  Bandanna_top_extent.
