This project aims to improve knowledge of coastal aquifer processes and management practices in order to increase the security of highly vulnerable freshwater. In particular, it aims to address critical barriers to the regional-scale investigation of coastal aquifers, including island lenses – the most vulnerable freshwater resources on earth. Threats to coastal aquifers are intensifying globally, and key knowledge gaps prevail in our current understanding and representation of transient, regional-scale seawater intrusion. The project plans to use coastal aquifer case studies from Australia and overseas to evaluate seawater intrusion reversibility, intermittent pumping effects, offshore aquifer processes, and management approaches. The project may improve coastal aquifer practices globally by unravelling the driving forces of transient seawater intrusion and developing new seawater intrusion models.

该项目旨在提高对沿海含水层过程和管理实践的了解，以提高高度脆弱的淡水的安全性。特别是，它旨在解决沿海含水层（包括岛屿镜片）的区域规模投资的关键障碍，包括地球上最脆弱的淡水资源。对沿海含水层的威胁正在加剧全球，关键知识差距在我们当前对瞬态，区域尺度海水入侵的理解和表示。该项目计划使用澳大利亚和海外的沿海含水层案例研究来评估海水入侵可逆性，间歇性抽水效果，离岸含水层过程和管理方法。该项目可以通过揭示瞬态海水入侵的驱动力并发展新的海水入侵模型，从而改善沿海含水层的实践。
