A particle-tracking model based on high-resolution ocean flow data was used to investigate particle residence times and spatial distribution of settling sediment for two geo-morphologically different Swedish coastal areas. The study was a part of a safety assessment for the location of a future nuclear-waste repository, and information about the particle-transport patterns can contribute to predictions of the fate of a possible leakage. It is also, to our knowledge, the first time particle-transport differences between two coastal areas have been quantified in this manner. In Forsmark, a funnel-shaped bay shielded by a number of islands, the average residence time for clay particles was 5 times longer than in the modeled part of Simpevarp, which is open to the Baltic Sea. In Forsmark, <10 % of the released particles left the domain compared to 60-80 % in Simpevarp. These site-specific differences will increase over time with the differences in land uplift between the areas.
基于高分辨率海洋流数据的粒子追踪模型被用于研究两个具有不同地貌特征的瑞典沿海地区沉降泥沙的粒子停留时间和空间分布。该研究是未来核废料处置库选址安全评估的一部分，有关粒子输运模式的信息有助于预测可能泄漏的后果。据我们所知，这也是首次以这种方式量化两个沿海地区之间的粒子输运差异。在福斯马克（Forsmark），一个被多个岛屿屏蔽的漏斗形海湾，粘土颗粒的平均停留时间比模拟的斯莫皮瓦尔普（Simpevarp）部分长 5 倍，斯莫皮瓦尔普部分向波罗的海敞开。在福斯马克，与斯莫皮瓦尔普的 60-80%相比，<10%的释放粒子离开该区域。随着这些区域之间陆地抬升的差异，这些特定于地点的差异将随着时间的推移而增加。
