ALONGSHORE SEDIMENT TRANSPORT IN THE AREA OF TROPICAL CYCLONE PASSAGE (HICACOS PENINSULA, CUBA)
The paper presents the results of the climatic features of alongshore flows of bottom sediments analysis. The object of research is the Icacos Peninsula coastal zone in the northern part of Cuba. On the peninsula, there are beaches of world importance (Varadero), which have noticeably degraded over the past decades, and there is a general erosion and a decrease in their areas. The main purpose of this work is to analyze the features of the alongshore sediment transport in the Icakos Peninsula area for the period from 1990 to 2019. The components of surface waves are considered as a transport mechanism: pure wind waves and swell. Research method – mathematical modeling. Surface wave parameters were obtained using the modern DHI MIKE 21 SW spectral wave model. To estimate the volumes of transported sediments, a mathematical model is used that calculates the flows of non-cohesive sediments under the influence of wind waves. In contrast to the seas of the temperate climatic zone with a pronounced seasonal variation of hydrometeorological parameters, the climate of the coastal zone of Cuba is determined by constant northeastern trade winds and the passage of irregular tropical cyclones.
