| Abstract | 本文发展了一套适用于模拟我国南海北部小尺度沙波运移的数值模型,该模型由超高分辨率三维海洋环境数值模块和泥沙运移模块组成,综合考虑了地形、潮汐、温盐和风应力等因素对海底流场和沙波运移的影响,可模拟时间间隔一年以上的沙波运移.研究发现,沙脊两侧沙波运移方向相反是潮汐、地形与温盐三方面因素综合作用的结果,其中温盐分布所导致的密度流是沙波运移中不可忽略的因素之一.与实测结果比较证明,本文模拟结果优于2DV模型和Q3D模型,并且可模拟沙脊两侧沙波运移方向翻转的现象. |
| Other Abstract | This paper developed a numerical model applicable to the simulation of small-scale sandwaves migration in northern South China Sea. The model is composed of ultra-high resolution 3D ocean environment module and sediment transport module, considering the impact of terrain, tides, temperature, salinity and wind stresses on the bottom flow field and the sandwaves migration. The study found that sandwaves migrations with opposite direction on the two sides of the sand ridge resulted from the joint effects of terrain, tide, temperature and salinity. Among them, the density current induced by temperature and salinity distribution is one of the factors that cannot be ignored in the sand wave migration. Comparing with measurement results, the simulation results are better than the previous 2DV model and the Q3D model; the model can simulate the phenomenon of sandwaves migration direction flip on both sides of the sand ridge. |
