In this study, transport and possible accumulation of microplastic marine litter in enclosed coastal waters are modeled numerically. The model is applied to the Fethiye Inner Bay, located in Fethiye-Göcek Specially Protected Area. In modeling studies, three dimensional coastal hydrodynamics, transport and water quality numerical model HYDROTAM-3D was used. The current climate was prepared by modeling long-term circulation patterns due to wind, wave and density stratifications. Following the hydrodynamic studies, the advection and diffusion of 3 mm size polystyrene particles by the coastal currents in the surface waters of Fethiye Inner Bay were simulated. The coastal regions where the microplastic pollution will be concentrated and transported were determined by the modeling scenarios. It has been found that microplastic accumulation is expected in the southwest and east coastal waters of the Fethiye Inner Bay. The results of the model will contribute to the databases for sustainable protection of the marine environments.
在这项研究中，对封闭沿海水域中的海洋微塑料垃圾的迁移和可能的积累进行了数值模拟。该模型应用于费特希耶-戈切特别保护区内的费特希耶内湾。在建模研究中，使用了三维沿海水动力、输运和水质数值模型 HYDROTAM-3D。通过模拟风、浪和密度分层等因素引起的长期环流模式，为当前气候进行了建模。在水动力研究之后，模拟了表面水中费特希耶内湾沿岸流对 3 毫米大小聚苯乙烯颗粒的输运和扩散。通过建模方案确定了微塑料污染集中和迁移的沿海区域。研究发现，费特希耶内湾的西南和东部沿海水域预计会有微塑料积累。该模型的结果将为海洋环境的可持续保护数据库做出贡献。
