摘要:
本文用多元统计分析阐述了连云港附近岸滩表层沉积物的粒度特征,以及沉积物的平均粒径与波浪、潮流最大底切速之间的密切关系,从而得到沉积物运动的判据,它对预测岸滩冲淤亦具有一定的实际意义。

A MOVEMENT DISCRIMINATION OF SURFACE SEDIMENT NEAR BEACH OF THE LIANYUNGANG AREA
Abstract:
This paper discusses mean grain size character of surface sediments near beach of the Lianyungang. Better relationships between mean grain size and maximum bottom shearing force of wave and current is found using a multivariate statistical analysis. As a result, sediment movement can be discriminated. Which is of practical significance for predicting beach erosion and deposit variations.
