Contaminant Transport in Marine Sediment

污染物在海洋沉积物中的迁移。海湾和河口的沉积物经常受到污染。沉积物中的无机污染物可以通过传质过程释放回水体。传质速率在很大程度上受波浪驱动的渗流通过海床的控制。因此，对这一通量的量化是模拟沿海水体水质的一个关键因素。该项目的目标是：(1)建立波浪引起的沉积物渗漏通量和污染物运移的模型；(2)建立渗漏通量和污染物运移之间的联系。拟议研究的结果将加强对污染物在海洋沉积物中迁移机制的了解。

Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated. The inorganic contaminants in sediments can be released back into the water body through mass transfer processes. The mass transfer rate is largely controlled by the wave-driven seepage flux across the seabed. Quantification of this flux is thus a key factor in modelling water quality of coastal water bodies. This project aims to: (1) develop models forwave-induced seepage flux within sediments and contaminant transport; and (2) establish the link between seepage flux and contaminant transport. Outcomes of the proposed research will enhance the understanding of the mechanism of contaminant transport in marine sediment.
