Quantifying near-surface diffuse discharge from the southwest Great Artesian Basin

点击翻译按钮获取中文摘要

Groundwater from the Great Artesian Basin (GAB) supplies one of Australia's largest mining operations and many pastoral enterprises. The GAB is the only significant water resource through much of arid central Australia and supports unique environmental values in this region. This project will provide vital data on natural, near-surface leakage rates from the GAB that can be used to gain a greater understanding of the amount of water available for sustainable extraction. This will assist in the improved management of the GAB resource and in doing so contribute to greater certainty for the mining and pastoral users of the GAB groundwater and provide greater protection for unique ecosystems associated with natural discharge springs.
