收集了近年来鳌江口附近海域多个工程不同阶段5个潮位站的3-5年潮位实测数据和部分海流实测资料，通过对鳌江口附近海域的不同年份的水位资料进行潮汐调和常数分析，鳌江近海海域主要为半日潮区，其中 M2分潮的振幅在170~193 cm；迟角在260°~280°之间，这些站的2007年、2010年、2011年调和常数分析结果相比，主要的半日分潮 M2、S2、N2，全日分潮 K1、O1及浅水分潮 M4、MS4、及 M6等分潮振幅、迟角的最大变化分别在1.8~4.4 cm 和3°~7°之间。在初步掌握了鳌江口潮汐潮流特征的基础上，采用无结构的三角形网格和有限体积法的 FVCOM 海洋数值模型，进行模拟结果验证，计算结果与实测数据符合良好。构建重点年份建设工程合拢产生新的岸线水深的潮汐潮流场，刻画鳌江口建设工程的叠加影响。

This paper have collected the measured tides and some tidal currents measured data in different stages of many projects in past three to five years near the Aojiang River. The harmonic method is used to analyze tide and tidal currents data observed at five stations in the sea adjacent to Aojiang River. The results show that the tide is mainly regular semidiurnal in the sea adjacent to Wenzhou Aojiang. The tidal amplitudes of M2 constituent are between 170 ~193 cm and the lags are between 260~280°. According to the comparison of analytical results of harmonic constants of these stations in 2007, 2010, 2011. The maximum change of tidal amplitudes and phase-lags range for the main semidiurnal tides (M2、 S2、 N2) , the diurnal tide (K1、 O1) and the shallow water tide (M4、 MS4、 M6) are 1.8~4.4 cm and 3°~7°, respectively. After analyzing the tide and tidal current characteristic of Aojiang River, this paper used an unstructured grid and finite-volume coastal ocean model (FVCOM) to test the result of simulation. The simulated results agree well with the measured data. The new shoreline and depth produced by the construction projects are closed in major years, the tide and tidal current field for the new shoreline and depth are constructed. This characterizes the superimposed influences of construction engineering in Aojiang estuary.
