Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwater dynamics over a range of time scales. The outcome will help to assess the extent and intensity of mass and momentum exchanges across the beach face, and the resulting effects on beach stability and the fate of contaminants in coastal aquifers.

海滩地下水是一个与潮汐、波浪和冲刷相互作用的高度复杂的动态系统。这种相互作用影响着海滩沉积物的移动和沿海含水层中污染物的迁移/转化。该项目旨在测量三种不同类型海滩的地下水行为并建立模型：沙滩、砾石和砾石-沙滩混合海滩。这项研究将提供急需的理解和量化的海滩地下水动态在一系列的时间尺度。其结果将有助于评估整个海滩表面质量和动量交换的程度和强度，以及由此对海滩稳定性和沿海含水层污染物命运的影响。
