Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments

沿海沉积物中污染物在波浪作用下的运输和转化的多孔弹性单畴模型。澳大利亚许多海湾和河口的沉积物由于河流、地下水或/和海洋排放口排放的废物而受到污染物污染。以往的研究大多采用多领域的方法，忽略了波浪驱动的对流和海岸沉积物中土壤行为的影响。在本研究中，我们将采用单域方法耦合沉积物-水界面附近的污染物输运过程，并将波浪驱动的对流流与海洋沉积物中的污染物联系起来。研究结果将更好地预测污染物在污染沉积物中的转化行为。

Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport near the sediment-water interface by a single domain approach, and link wave-dirven advective flow and contaminant in marine sediments. The research outcomes will provide a better prediction of the transformation behaviour of pollutants in contaminated sediments.
