Beach groundwater dynamics: measurement and modelling

滩涂地下水是一个高度复杂的动态系统，与潮汐、波浪和冲刷相互作用。这种相互作用影响海岸含水层的海滩沉积物运动和污染物运输/转化。该项目旨在测量和模拟地下水在三种不同类型的海滩上的行为：沙子，砾石和砾石-沙子混合海滩。这项研究将在一定的时间尺度上提供对海滩地下水动态的理解和量化。结果将有助于评估整个海滩表面的质量和动量交换的程度和强度，以及由此产生的对海滩稳定性的影响和沿海含水层中污染物的命运。

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.
