基于Matlab的江苏沿海潮位水文频率分析

Hydrological frequency analysis of the tide level along the coast of Jiangsu based on Matlab

本研究针对江苏省沿海潮位的特点,利用Matlab软件强大的工具箱和图形处理技术,编制皮尔逊Ⅲ型频率曲线分析计算的M文件,同时给出水文频率分析在人机交互界面上的运行效果。通过编程计算,得出不同频率情况下各沿海潮位站对应的潮位计算结果,并将其与原成果进行了比较和分析,进一步论证了设计潮位所采用成果的合理性和可行性。

According to the characteristics of the tide level along the coast of Jiangsu Province,the M files are compiled for analyzing the Pearson type Ⅲ frequency curve by Madab optimization toolbox and graphics processing technology.The operation effect of hydrological frequency analysis on human computer interaction interface is presented.By programming calculation,the tide calculation results of the coastal tide stations under different frequency are given.The rationality and feasibility of the design tide results are demonstrated through the comparison and analysis of the factors with the original tide level.
