This dataset also serves as the Alluvial Groundwater model extent for the Gloucester subregion.

Dataset History

Selected Alluvium polygons from the Dungog 1:100K Geology (see lineage) were appended to the source Avon Wards River Alluvium data.

Polygons were selected from the Geology layer as follows. First a spatial selection of polygons that intersected with the Gloucester PAE. From these, polygons where 'DomLith' = "alluvium" subselected.

The resultant combined data was exported to a new shapefile in the MGA zone 56 projection.

All processing was done in ArcGIS 10.2
