【 摘 要 】

This paper presents the seawater surface elevation in Gulf of Manado with numerical approach. The RANS shallow water flow equation is used to obtain a numerical equation of seawater surface elevation with a semi-implicit approximation approach in which the pressure distribution in the vertical layer of seawater is assumed hydrostatic. The results found that the high seawater level is not more than 1.81 m upper seawater level and 1.30 m under seawater level respectively. The results can be used as a recommendation to predict the condition of sea waves in the Gulf of Manado.
