Abstract

The results of analysis of climatic peculiarities of the alongshore fluxes of bottom sediments are presented. The object of research is the coastal zone of the Hicacos Peninsula in the northern part of Cuba. The main goal of this work is to analyze the peculiarities of alongshore transport of bottom sediments in the region of the Hicacos Peninsula in the period from 1990 to 2019. Components of surface waves are considered as a transport mechanism: pure wind waves and swell. The research method is mathematical modeling. The parameters of surface waves were estimated using the modern DHI MIKE 21 SW spectral wave model. A mathematical model, which calculates the fluxes of noncohesive material under the influence of wind waves, is used to estimate the volumes of transported bottom sediments. It was estimated that the annual mean (climatic) values of the fluxes from east to west are 45 000 m³/year, while those from west to east are about 11 000 m³/year. The contribution of individual tropical cyclones to the annual fluxes can be very significant; they are measured in tens of percent.

热带气旋传播区域的沙沉积物近岸通量（古巴希卡科斯半岛的例子）

摘要

给出了底部沉积物近岸通量的气候特征分析结果。研究的对象是古巴北部希卡科斯半岛的沿海地区。这项工作的主要目的是分析1990年至2019年期间Hicacos半岛地区底部沉积物沿岸传输的特殊性。表面波的组成被认为是一种传输机制：纯风波和涌浪。研究方法是数学建模。使用现代DHI MIKE 21 SW光谱波模型估算表面波的参数。使用数学模型来计算在风波的作用下非粘性材料的通量，以估算所运输的底部沉积物的体积。³ /年，而从西到东的那些大约是11000 m ³ /年。各个热带气旋对年通量的贡献可能非常大；它们以百分之十的百分比来度量。
