The nonlinear interation induced tidal period and water level fluctuation obviously . the bottom friction effect is direct ratio to the bottom friction coefficient . the bottom friction effect reduces the set up water level , and minish the set up 非线性效应是造成风暴潮增水水位明显波动的原因，底摩擦效应对潮位的贡献与底摩擦系数成正比，底摩擦效应使增水水位降低，减小了增水的幅度。
These tables list the predicted heights and times of daily high and low waters at the eight locations chi ma wan , ko lau wan , lok on pai , quarry bay , tai o , tai po kau , tsim bei tsui and waglan island . phases of the moon are also given 潮汐表列出本港8个地点芝麻湾、高流湾、乐安排、 ?鱼涌、大澳、大埔? 、尖鼻咀及横澜岛的每日最高及最低潮位和出现时间的预测，潮汐表亦附上月亮盈亏的资料。
On the base of multiple function realization of tidal level forecasting of storm - surge , dyke break flood computation , flood inundation area computation and manpower - material dispatch etc . and using fussy policy - decision method , the flood control policy - decision scheme was determined 并在实现风暴潮潮位预报、溃堤洪水计算、洪水淹没面积和人员物资的调度等多种功能基础上，运用模糊决策方法，生成长兴岛防洪决策方案。

The verification results show that the model can simulate well the tidal levels , current velocities , sediment concentration , bed load transport , diversion ratio in the bifurcation section , topographic change of the north and south channels , as well as sudden siltation caused by typhoons 大量实测资料验证表明，该数学模型可以较好地模拟长江口地区的潮位、流速、流向、含沙量、底沙、分流比、南北槽地形变化和台风暴潮造成的航道骤淤情况。
Second , on the basis of supplementing basic data and investigating the historic tidal level , the design tidal level has been analyzed and calculated . as the result of the comparison between p - iii type frequency curve and gumbel curve , the p - iii curve is recommended 其次，在插补延长基本资料、历史潮位考证的基础上，进行了设计潮位的分析计算，并分别就采用p -型曲线及gumbel曲线两种线型适线进行比较探讨，推荐采用p -型曲线适线成果。
In the study of quantitative forecast models , composition analysis for three different time series are firstly investigated by statistic test methods . the conclusions are as follows : there is no evident tendency for above three series , and evident periodicity exist only in precipitation series 在定量预测模型研究中，先对三个不同系列进行时间系列的组成分析，结果表明：三个系列均无趋势存在，降水量系列有明显周期存在，但年最高潮位系列无周期。
