水下地形冲淤变化对比分析的方法

Analytic Comparison between Seabed Topographic Changes Due to Accretion and Erosion

本文以某港区定期测量的水深图为依据,通过多种方法对比分析了水下地形的冲淤变化,归纳总结出了根据水深图进行冲淤变化分析所常用的方法,实际应用价值大。

Yet underwater terrain changes due to sediment accretion and corrosion at the site of a port has been analyzed by the method of comparison between bathymetric charts mapped at different times. From the analyses a number of methods commonly used for finding out the scouring-erosion variation patterns have been summarized. The methods may be of significant importance in the practical application.
