Comparison Among Different Methods for Tidal Prism Calculation& Neap Tide of Jiaozhou Bay in Autumn 2006 as an Expounded Example 不同方式的纳潮量计算比较&以胶州湾2006年秋季小潮为例
On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide. 三年平均而言,冬季悬沙浓度为夏季的2.0倍,大潮悬沙浓度为小潮的2.8倍;
In spring tide, the magnitude of salt flux during the South Channel is more than that in the North Channel, while on the contrary during the neap tide. 在大潮期间,进入南港的盐量较多,在小潮期间,进入北港的盐量较多。
The salinity is mainly influenced by the saltwater intrusion from the outer sea during spring and early middle tide, and by the saltwater intrusion from upstream during neap and later middle tide. 在大潮和中潮前期,盐度主要受下游外海盐水入侵的影响,在中潮后期和小潮期间,盐度主要受大潮期间上游北支倒灌盐水下移的影响。
During the period of neap tide, the case is reversed. 在小潮期则反之。
It is shown from the calculation results that there was a significant relationship between suspended sediment median grain size and concentration during the neap tide in November 2003, but there was not a significant relationship between the two during the spring tide; 结果表明,2003年11月小潮期间,悬沙中值粒径与悬沙浓度存在着显著的指数关系,在大潮期间没有显著关系;
In neap tide, near-bottom shear stress would increase with the rise of tidewater. The maximum value would occur in medium-term tide. 小潮近底剪切应力随潮位升高而增大,较大值一般出现在潮流中期。
Today, globalization has become a worldwide tide, significant wave. Tread of anti-globalization of thought is a neap tide, submarine tide. 如今,全球化已经成为一股世界性大潮、显潮,反全球化思潮还是一股小潮、潜潮。
Through a comparative analysis of index of formulas, we found the sediment carrying capacity in mean tide has a lot of enhancement compare to neap tide, but the increase is not obvious between the spring tide and mean tide period. 而且其挟沙力公式的拟合指数项显示出从小潮至中潮挟沙能力有明显增强,中潮到大潮时挟沙能力有一定增幅。
The processes of surface elevation, current velocity in the compound fluid model and suspended sediment concentration in the suspended sediment transport model are verified by observed data of many stations in flood/ dry season and in spring/ middle/ neap tide. 复合流场模型的水位过程、流速过程,以及悬沙模型的含沙量过程则经过了洪、枯季及大、中、小潮的多个站点的实测过程验证。
Due to the larger net unit residual flux during the neap tide, the oil film was transported farther downstream in the neap tide through a whole tidal period. 由于小潮期间单宽余通量大于大潮,经过完整的潮周期后,油膜向下游输运的距离小潮大于大潮。
