TIDAL CURRENT PATTERN MODELING USING THE MIKE 21 IN JAKARTA-CIREBON WATERS

Abstract

Tides are the process of rising and falling sea levels caused by the gravitational force of celestial bodies, especially the sun and moon, on sea water masses on earth. Tidal current data provides a picture of hydrodynamics in coastal areas and can be used for coastal development planning and for disaster mitigation in coastal areas. The aim of this research is to determine the modeling of tidal currents using the Flow Model Mike 21 method. The research was carried out in March - April 2023, located along the waters of Jakarta - Cirebon, while data collection and processing was carried out at Pushidrosal TNI-AL, Jakarta. The results of data processing and analysis resulted in modeling of tidal current patterns along the Jakarta - Cirebon waters, where the tides are of a mixed type with a single daily inclination, the average current speed is 0.307 m/s with the maximum speed occurring around the Cirebon waters at 0.592 m/s and The minimum speed occurs around Jakarta waters at 0.023 m/s.
