Hydrodynamics in Sagulung waters, Batam City, Riau Islands Province, for the Construction of a Private Port

Abstract

Batam is an archipelagic area in Indonesia. Batam has the advantage of being geographically close to neighboring countries, Singapore and Malaysia. The construction of a private port requires oceanographic studies of shipping lanes to the port. This study aims to provide information on the physical oceanographic conditions in the waters of Sagulung, Batam, Indonesia. The method in this study uses the MIKE 21 HD Flow Model FM. The data on high sea waves in this study for the last five years (2019-2022), collected from the Copernicus Marine Environment Monitoring Service (CMEMS). The results of this study show that the ocean current pattern around the location tends to have low speeds during both each tidal phase and the average conditions. The current speed conditions at the port-planning location during both the spring and neap periods are less than 0.2 m/s. This shows that the study location is a good place for a private port. The construction of private ports is best conducted from May to June and also from August to September because in those months the significance wave value is low.
