查询词典 tidal

Considering complicated conditions of the coastal dynamic environment, sediment dynamics, and together with the immature sediment itself, the predicted results will be somewhat limited if only with numerical model. So, in order to obtain microcosmic quantitative assessment and macroscopically understanding, numerical model is combined with field observations in the thesis.

Then, the tidal current, SSC distribution, and the erosion and accumulation of the seabed were simulated with the numerical model of ECOMSED.

Studies showed that there were two typical combinations of the facies in the filling sedimentary sequence of the epicontinental basin, wherein one was the depositional diastem developed between the facies, which was a discontinuous combination of the depositional facies with continuous time sequence, namely the exposed sediments, the tidal flat swamp and the peat swamp, and the shallow marine sediments appeared from bottom to top; and the other was the continuous sequence with gradually evolved sedimentary environment, in which it was a continuous process that the tidal flat swamp turned gradually into the peat swamp.

研究表明：陆表海盆地充填沉积序列中有两种较为典型的相组合，一是相与相间发育沉积间断面，为不连续沉积相组合，但在时间序列上是连续的，即自下而上依次为暴露沉积、潮坪沼泽及泥炭沼泽、浅海沉积；第二种序列是连续相序，盆地的环境演化是渐变的，潮坪沼泽化逐渐泥炭沼泽化是一个连续过程。

A quick and correct forecast of tidal current when oil spill occurs is a key step in the forecast of oil spill. Based on the harmonic constant of tidal component of M2, S2, O1 and K1 in Lingshan Island, Laoshantou and Chaolian Island, and by using harmonic method, the thesis first conducts a current forecast in a single point, and then builds up a current field forecast in Jiaozhou Bay and its adjacent seas. The computed results match well with the actual situation. The method reduces greatly the time of real time current forecast by not using numerical stimulation, so it fit to the two requirements of quickness and correctness in oil spill forecast system.

迅速准确地预测出溢油发生时的潮流情况是溢油环境预测的根本保证，因此文中根据灵山岛、崂山头和朝连岛三处M2、S2，、O1和K1四个主要分潮的调和常数资料，采用调和的方法进行单点的潮流预报，进而建立了胶州湾及邻近海域的预报潮流场；该方法的潮流预报结果与实际情况吻合良好，且因避开了数值计算过程而大大减少了流场实时预报的机时，符合溢油应急预报系统所要求的准确与快速。

The numerical results show that the ocean models in diurnal band are more stable than those in semidiurnal band, and the correction of the change in tidal height plays a significant role in determining accurately the phase lag of the tidal gravity.

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.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.
