摘要:

通过对高、低潮位数据插值和NS_TIDE模型应用,分析西江感潮河段(马口—大横琴)的潮汐特征。对比三种插值方法发现,相对于三次样条插值法和线性插值法,Hermite插值法对逐时潮位的模拟效果最佳。潮位验证结果显示NS_TIDE模型总体误差较低,异常值主要是源自台风和洪水的影响。西江感潮河段平均水位和分潮振幅存在洪、枯季差异,上游受径流的影响大于潮汐,下游则相反;径流量和潮差增大,促进上游河段平均水位增高,对分潮振幅和迟角的影响在不同河段表现不同,主要与其所处空间位置和分潮自身频率有关。

Abstract:

By interpolation of high and low tide data and application of NS_TIDE model, the tidal characteristics of the tidal reach of Xijiang River (Makou-Dahengqin) were analyzed. Compared with cubic spline interpolation and linear interpolation, it is found that Hermite interpolation is the best method to simulate the hourly tide level. The verification results of tide level show that the overall error of NS_TIDE model is low, and the outliers mainly come from the influence of typhoon and flood. The mean water level and the amplitude of tidal component in the tidal reach of Xijiang River are different in wet and dry season. The influence of runoff in the upper reaches is greater than that of the tides, and the opposite is true in the lower reaches. With the increase of runoff and tidal difference, the mean water level of the upper reaches increases, and the influence on the amplitude and the phase of tidal component is different in different section, which is related to the spatial location and the frequency of the tidal component.

Key words: high and low water interpolation, harmonic analysis, river discharge, ocean tides
