利用高低潮推算乘潮水位的方法

提出一种仅利用高低潮数据计算乘潮水位的新方法.以潮汐表中我国不同潮汐类型站点的高、低潮数据和逐时潮位数据为基础,采用按规范方法计算的结果对新方法的结果进行验证,从多角度分析计算误差.结果表明,新方法的计算结果误差多在10 cm以内,径流和浅水分潮影响明显区域的最大误差在20 cm左右,结果精度能够满足工程需求.此方法含...

Method of calculating tide riding water level by high and low tide

We propose a new method to calculate the tide riding water level only using the high and low tide data.Based on the tide table s data of the high and low tide data and hourly tide level data from tidal stations of different tide types in China,we use the calculation results by the standard method to verify the results of this method,and analyze the calculation error from multiple aspects.The results show that most of the new method s errors are within 10 cm,and the maximum error is about 20 cm in the area which is obviously impacted by runoff and shallow water tidal component.Thus,the results of the new method can meet the engineering requirements.This method has clear physical meaning,simple formula and can be easily solved by calculator or Excel software.This method can be used to calculate the tide riding water level in the sea area lacking hourly tide level data.
