Delineation of geology and groundwater resources in a frontier region: Western Davenport, Northern Territory

The Western Davenport region has been identified as an area of interest for future agricultural development. However, realisation of this potential depends on access to a reliable supply of groundwater, underpinned by rigorous geological and groundwater information. A three-dimensional stratigraphic model has been created for the Western Davenport area of the Southern Stuart Corridor project under the Exploring for the Future program. Our interpretation integrates airborne electromagnetic data with historical drillhole and outcrop data to improve geological and hydrogeological understanding. Results show that stratigraphies of the Wiso and Georgina basins are equivalent and laterally continuous in this area. This enables a more complete hydrostratigraphy to be defined and underpins improved hydrogeological conceptualisation. New hydrochemical data support the conceptual model that the aquifers of the Wiso and Georgina basins are interconnected at a regional scale. The initial assessment of water quality indicates that groundwater may support further agricultural development. Analysis of new water chemistry data has improved understanding of groundwater processes and potential areas of recharge. This work will inform management decisions to enhance the economic and social opportunities in the Western Davenport area, while protecting the environmental and cultural value of water resources.

Statement

This study was completed under the Exploring for the Future initiative, as part of the Groundwater component. Interpretation integrated airborne electromagnetic data with historical drillhole and outcrop data to improve geological and hydrogeological understanding in the Western Davenport area. Water bore drilling, groundwater samples and water level measurements were collected during fieldwork in 2018 and 2019. Hydrochemistry datasets are available through the Geoscience Australia portal ( https://portal.ga.gov.au/) and are published in GA hydrochemistry database ( https://pid.geoscience.gov.au/dataset/ga/100521). Hydrochemistry data was supplements with data from the Northern Territory chemistry database to characterise total dissolved solids across the Western Davenport area. An integrated report presenting findings from the project are published in GA Record https://pid.geoscience.gov.au/dataset/ga/133989.
