CLM - Bore assignments NSW

Abstract

The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from the NSW Office of Water - National Groundwater Information System 20140701 dataset. You can find a link to the parent dataset in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.

This dataset contains the aquifer assignment results for the NSW part of the Clarence-Moreton Basin. The data were organized by hydrostratigraphic units. Assigning a bore to a specific aquifer is underpinned by the screened interval data and the aquifer boundaries. In many cases, it is impossible to assign the screened interval of a bore to a single aquifer as bores are either screened across different aquifers or there is insufficient information on stratigraphy and screened intervals. Bores were assigned to aquifers by comparing their screen intervals and depth with aquifer boundary data. The required information was extracted from the NGIS database.

Dataset History

The following steps were followed during the aquifer assignment:

1. Assess the boundaries of aquifers.

2. Determine the screen intervals of bores.

3. Determine the screen interval of bores for the Queensland bores.

4. Filter bores for a specific area using a shape file or coordinates.

5. Cross-check the final datasets against expert knowledge and spatial context of aquifers.
