Numerical Modeling of Coastal Tides and Current Pattern at Northern Peat Coast of Bengkalis Island

---

This research aims to determine the types of tides and current patterns in the north coast of Bengkalis Island. This research uses the Delft3D coastal hydrodynamic simulation model. The data used includes secondary data such as bathymetry data, tides and current speed at the research location. The calibration process is carried out using the Manning value and the reflection parameter alpha. Tides are analyzed using the Least Square method to obtain tidal harmonic constants. The hydrodynamic model is composed of several rectilinear numerical grids. Boundary conditions use tidal harmonic constants. Physical parameters using Copernicus hourly data include atmospheric pressure and wind.
The research results show that the tidal type is mixed, predominantly semidiurnal, with a Formzhal value of 0.377. Changes in water level elevation are not very significant except during spring tide, with a height difference of up to 27mm. The average current speed at high tide is 0.21m/s and at low tide it is -0.232m/s. The tidal current pattern is dominated by the south and southwest directions, while the ebb direction is towards the northeast. The distribution of wind speed is generally dominated between 0 and 20cm/s with a percentage of 66.9%.
