摘要
应用一种非结构网格海洋模式(FVCOM)建立了洞头列岛及其临近海域的水动力数值模式,水平方向三角网格的采用使模型对大陆海洋线以及岛礁边界的拟合达到了很高精度。经流速、流向和潮位验证后,精度良好的模型被用于人工渔礁区选址的研究。以大潮底层最大流速和大潮底层平均流速为主要判别指标,结合海域地形和水深分布,选定了底层最大流速小于0.6 m/s、平均流速小于0.4 m/s的海域为适宜人工渔礁建设的礁区范围。
An unstructured grid based numerical ocean model(Finite Volume Coastal Ocean Model,FVCOM) is applied to the study of hydrodynamics in offshore area near Dongtou and its adjacent area.The adoption of horizontal triangle grids makes the model fit to the land and islands boundaries easily and accurately.The computed data of tidal currents velocity,direction and tidal elevation are validated by the data observed before the model is applied to artificial reef set selection study in Dongtou area.Considering the t...
