“…We can see that the power available distributions when high tide currents (Figure 6b) at in front of the Singkil river downstream (Figure 4b) where around 80-105 kW/m 2 bigger than the other area in around that of 1-60 kW/m The distributions of the power available when low and high tide currents in the Manado Bay (3D-simulation) at discharge 0.1 Sv respectively showed in Figure 7. Tide currents very influence to the power available which very big at high tide current [25][26][27]. When low tide currents, the distributions were 0.00-20.00 kW/m 2 and 0.00-105.00 kW/m 2 when high tide currents in the Manado Bay.…”

This study is investigating about marine currents provided electrical energy through the numerical model. The objective of this study is to know the power available distributions in the Manado Bay, North Sulawesi, Indonesia. The Manado Bay was width 2200 m with 79 m of depth. In computation, we are made grids in x and y horizontal were 7 m respectively, also for z vertical of four layers. The results shown that the power available distributions in the Manado Bay at 0.1 Sv were 0.00-20.00 kW/m 2 when low tide currents and when high tide currents were 0.00-105 kW/m 2 . The values will enable for marine currents power plant in the Manado Bay to future.

“…The numerical modeling equations used diffusion step [11] with a general semi-implicit discretization of the momentum equations in equations (3) and (4) to get the velocities while the seawater surface elevation used equation (5). The velocities in x, y, and z directions, we can write in the more compact matrix form as in [2][3][4][5].…”

Abstract. 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. IntroductionThe horizontal and vertical motion of seawater occurs caused by the wind stress at the sea surface. If surface seawater is a divergence, water at the bottom will rise to surface and this situation will be happened upwelling; conversely, where it is a convergence and will happened downwelling. For condition where a system of cyclonic wind on surface seawaters where the average movement of the wind-driven layer is to the right of the wind which causing divergence of surface water and upwelling, and the sea-surface is lowered and the thermocline is raised, it is called Ekman pumping. In condition inverse correspond in anticyclone wind is convergence and sinking (downwelling), it causes the seasurface to slope upwards the middle of the gyre [1]. It will produce a sea wave called seawater surface elevation. Transport at the position of Gulf of Manado is convergence.A numerical modeling can predict seawater surface elevation. It conducted by [2][3][4][5] in the Straits of Bunaken and Bangka, North Sulawesi, Indonesia. The simulation seawater surface elevation from shallow water flows with a free surface correction method [6]. The distribution of seawater surface elevation with respect to a reference level (m) by study on modeling shallow water wakes using a hybrid turbulence model [7]. Calculating of seawater surface elevation by using the semi-lagrangian method and they compute the non-linear response of the full model due to a shear stress that comes from the action of the wind at the ocean surface [8]. Simulated seawater surface elevation in the variations of typical seasonal corresponding to the period 1956-1960 from the surface wind stress in the Aral Sea [9]. Also, Implemented fully-implicit time integration schemes in a version of parallel ocean program for calculation of seawater surface elevation by its simulation in the North Atlantic [10].The objective of this study was to get distribution of seawater surface elevation by using numerical modeling in the Gulf of Manado, North Sulawesi, Indonesia.
