This project aims to determine and quantify key mechanisms governing chemical transport and transformation in a tidally dominated subterranean estuary. The project will be the first attempt worldwide to measure simultaneously the temporal and spatial variability of coupled physical and geochemical processes in the intertidal zone of a subterranean estuary. The project will generate much-needed understanding of the role of subterranean estuaries in controlling fluxes of land-derived chemicals to the ocean via submarine groundwater discharge. The outcomes will have important implications for assessing and minimising the impact of groundwater contamination on the coastal zone. It will provide better understanding of the pathway of land-derived nutrients and contaminants entering coastal waters, leading to improvement of strategies for sustainable coastal resources management and development, and integration of upland and lowland catchments management.

该项目旨在确定和量化控制潮汐主导的地下河口化学迁移和转化的关键机制。该项目将是世界范围内首次同时测量地下潮间带物理和地球化学耦合过程的时间和空间变化的尝试。该项目将深入了解地下河口在控制陆地化学物质通过海底地下水排放进入海洋方面的作用。最大限度地减少地下水污染对沿海地区的影响将有助于更好地了解来自陆地的营养物和污染物进入沿海水域的途径，从而改进可持续沿海资源管理和开发以及高地和低地集水区的一体化战略。管理。
