Defining and controlling seawater intrusion in threatened coastal aquifers

该项目旨在增进对沿海含水层程序和管理做法的了解，以加强高度脆弱淡水的安全。特别是，它旨在解决对沿海含水层进行区域规模调查的关键障碍，包括岛屿透镜--地球上最脆弱的淡水资源。对沿海含水层的威胁在全球范围内正在加剧，我们目前对区域规模的瞬时海水入侵的理解和表述中存在着关键的知识空白。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的可逆性、间歇抽水效果、近海含水层过程和管理方法。该项目可能会通过揭示瞬时海水入侵的驱动力和开发新的海水入侵模型来改善全球沿海含水层的做法。

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.
