In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.

在干旱和半干旱气候中，水生和陆地生态系统往往依赖地下水泉水。春季水文取决于底层含水层和地表条件之间的复杂关系，导致在理解含水层-泉水-湿地水文方面存在很大的不确定性，而这对于保护春季生态系统和为管理影响地下水的相关活动提供信息至关重要。该项目将采用新的水文地球物理和水化学方法以及计算机建模，调查位于未来开发区的Doongmabulla Springs Complex（DSC）的水源含水层和排放物的命运。项目结果将告知春季对发展压力和气候影响的脆弱性。
