本文利用MIKE21FM数值模拟软件模拟了2000年和2014年莱州湾海域的水动力变化。结果表明由于海洋工程的建设,莱州湾内地形和浅滩发生变化,导致2014年湾内整体潮流流速较2000年减小,流向发生一定偏转;在NE向定常风驱动下对比2000年和2014年模拟海流结果可知变化幅度在1~3cm/s内,莱州湾整体表层海水运动受岸线变化影响较小;纳潮量减少0.1788 km~3,为2000年的3.2%;半水交换时间由27.5 d增加到29 d,工程建设对莱州湾水交换影响相对较小。
In this paper, using MIKE21FM numerical simulation software to simulate the 2000 and 2014 Laizhou Bay waters hydrodynamic changes. The results show that due to the construction of marine engineering, the change of the terrain and shoals in the Laizhou Bay led to the decrease of the overall tidal flow velocity in the Gulf in 2000 as compared with that of 2000, and a certain deflection of the flow direction. Compared with the simulated ocean current results of 2000 and 2014 It can be seen that within the range of 1 ~ 3cm / s, the overall surface seawater movement in Laizhou Bay is less affected by the change of shoreline; the natam decreases by 0.1788 km ~ 3, which is 3.2% in 2000; the exchange time of semi-water increases from 27.5 d to 29 d, the impact of the construction on Laizhou Bay water exchange is relatively small.
