Analisis Karakterisitk Gelombang Laut Di Perairan Sumatera Barat
ABSTRACT
The waters of West Sumatra to the west are directly adjacent to the Indian Ocean resulting in the potential for high wave events to occur quite frequently which has an impact on community activities and also the construction of coastal buildings. Therefore it is necessary to study the wave height. The research was carried out in February 2023 with the research location being carried out in the waters of West Sumatra with the coordinate point of the wind station I, namely longitude 99.84O E and latitude 0.98O S and wind station II longitude 98.59O E and latitude 2.48OS. The aim of this study was to analyze the height and period of sea waves in the waters of West Sumatra using wind speed distribution data and to determine the characteristics of sea waves based on the wind season for one year through a processing method, namely the Shore Protection Manual (SPM). From the results of the data processing carried out, it shows that the waves at station I belong to the low wave category. The highest significant waves occur in the dry to wet transition season with a significant wave height value of 0.95 m. Waves at station II are categorized as waves with the medium wave category with the highest significant wave height occurring in the west monsoon with a value of 1.48 m. In the analysis of the waves formed consists of fully developed waves and nonfully developed wave. Nonfully developed wave are divided into Fetch Limited and Duration Limited which are also found on both stations.
