【摘要】：河口擋潮閘閘下低潮水位資料周期性缺失可能導(dǎo)致閘下潮汐調(diào)和分析結(jié)果出現(xiàn)偏差,從而直接影響到閘下水位過程的預(yù)報精度。針對這一問題,提出了一種閘下低潮缺失水位的修正方法,利用潮汐過程曲線的對稱性對低潮缺失水位資料進行初步修正,然后根據(jù)調(diào)和分析自報結(jié)果對修正數(shù)據(jù)進行迭代更新,直至潮汐調(diào)和常數(shù)不再變化。驗證結(jié)果表明,該方法可有效提高閘下水位過程的自報精度,其成果在2014年寧波高背浦閘閘下測站的潮汐預(yù)報中得到了良好應(yīng)用。
[Abstract]:The periodic lack of low tide water level data under the gate may lead to the deviation of the harmonic analysis results of the tide under the gate, which directly affects the prediction accuracy of the water level process under the gate. In order to solve this problem, a correction method of low tide missing water level under sluice is proposed. The data of low tide missing water level are preliminarily modified by using the symmetry of tidal process curve, and then the modified data are updated iteratively according to the self-reported results of harmonic analysis until the tidal harmonic constant does not change. The verification results show that this method can effectively improve the self-reporting accuracy of the lower gate water level process, and its results have been well applied in the tide prediction of Ningbo Gaobupu sluice station in 2014.
