Great Artesian Basin - Cadna-owie Hooray Potentiometric Surface

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

Composite temperature and density corrected potentiometric surface contours for the Cadna-owie-Hooray and equivalents Aquifer and inferred regional groundwater flow directions comprises of two separate data layers; A: Potentiometric surface contours B: Regional groundwater flow direction arrows - Inferred The composite potentiometric surface contours are modified from (Ransley & Smerdon 2013) (figure 7.4 - Modern (Circa 2010) potentiometric surface) and Love et.al. (eds) 2013 (Figure 5.14 Present-day corrected potentiometric surface of the J aquifer for the variable temperature assumption) which was generated from a surface grid that is calculated from temperature and density corrected waterbore head measurements obtained between 2000 and 2010. The regional flow is inferred to occur down hydrualic gradient perpendicular to groundwater head isopotential contours.

Dataset History

SOURCE DATA: Data was obtained from a variety of sources, as listed below: 1. Ransley & Smerdon 2013) (figure 7.4 - Modern (Circa 2010) potentiometric surface) 2. Love et.al. (eds) 2013 (Figure 5.14 Present-day corrected potentiometric surface of the J aquifer for the variable temperature assumption) METHOD: Potentiometric surface contours Contours from data sources 1 & 2 were imported into ArcGIS. Within the SA/NT portion of GAB, contours from data source 1 were deleted and replaced by data source 2. Manual modification of potentiometric contours was carried out along the boundary of the two data sources to edge match the two datasets. Inferred Regional groundwater flow directions Inferred flow direction arrows were produced by manual interpretation in ArcGIS by drawing arrows perpendicular to the potentiometric surface contours. QAQC: Data has undergone a QAQC verification process in order to capture and repair attribute and geometric errors. SOFTWARE: All modifications/edits and geoprocessing were performed using ESRI ArcGIS 10 software.
