摘要
基于干湿网格的三维河口-陆架-海洋(ECOM3D)模式,并结合物质平流—扩散方程,模拟了海州湾近岸海域潮流场和污染物输运浓度场。分析了在不同风向情况下海州湾近岸海域拉格朗日潮余流的分布特征,并且分析了污染物在不同风向下时空分布特征。分析结果表明:在WSW向风作用下,污染物有利于向外海扩散;在E向风和ESE向风作用下,污染物向近岸堆积。
Based on a three dimensional estuary coast-ocean model (ECOM3D) which has a variable boundary and combined with matter adveetion-diffusion equation as well, the tidal current field and the contaminant transporting concentration field in the nearshore area of the HaizhouBay have been simulated. Meanwhile, analyses have been made of the distributions of Lagrange tide residuals and the temporal and spatial distributions of contaminants under different wind directions in the nearshore area of the Haizhou.Day. The results have indicated that under the actions of WSW winds the contaminants are favored to diffuse seaward, whereas under the actions of E and ESE winds they are accumulated coastward.
